+# SQL builder
+
+[![Build Status](https://drone.gitea.com/api/badges/xorm/builder/status.svg)](https://drone.gitea.com/xorm/builder) [![](http://gocover.io/_badge/xorm.io/builder)](http://gocover.io/xorm.io/builder)
+[![](https://goreportcard.com/badge/xorm.io/builder)](https://goreportcard.com/report/xorm.io/builder)
+
+Package builder is a lightweight and fast SQL builder for Go and XORM.
+
+Make sure you have installed Go 1.8+ and then:
+
+    go get xorm.io/builder
+
+# Insert
+
+```Go
+sql, args, err := builder.Insert(Eq{"c": 1, "d": 2}).Into("table1").ToSQL()
+
+// INSERT INTO table1 SELECT * FROM table2
+sql, err := builder.Insert().Into("table1").Select().From("table2").ToBoundSQL()
+
+// INSERT INTO table1 (a, b) SELECT b, c FROM table2
+sql, err = builder.Insert("a, b").Into("table1").Select("b, c").From("table2").ToBoundSQL()
+```
+
+# Select
+
+```Go
+// Simple Query
+sql, args, err := Select("c, d").From("table1").Where(Eq{"a": 1}).ToSQL()
+// With join
+sql, args, err = Select("c, d").From("table1").LeftJoin("table2", Eq{"table1.id": 1}.And(Lt{"table2.id": 3})).
+		RightJoin("table3", "table2.id = table3.tid").Where(Eq{"a": 1}).ToSQL()
+// From sub query
+sql, args, err := Select("sub.id").From(Select("c").From("table1").Where(Eq{"a": 1}), "sub").Where(Eq{"b": 1}).ToSQL()
+// From union query
+sql, args, err = Select("sub.id").From(
+	Select("id").From("table1").Where(Eq{"a": 1}).Union("all", Select("id").From("table1").Where(Eq{"a": 2})),"sub").
+	Where(Eq{"b": 1}).ToSQL()
+// With order by
+sql, args, err = Select("a", "b", "c").From("table1").Where(Eq{"f1": "v1", "f2": "v2"}).
+		OrderBy("a ASC").ToSQL()
+// With limit.
+// Be careful! You should set up specific dialect for builder before performing a query with LIMIT
+sql, args, err = Dialect(MYSQL).Select("a", "b", "c").From("table1").OrderBy("a ASC").
+		Limit(5, 10).ToSQL()
+```
+
+# Update
+
+```Go
+sql, args, err := Update(Eq{"a": 2}).From("table1").Where(Eq{"a": 1}).ToSQL()
+```
+
+# Delete
+
+```Go
+sql, args, err := Delete(Eq{"a": 1}).From("table1").ToSQL()
+```
+
+# Union
+
+```Go
+sql, args, err := Select("*").From("a").Where(Eq{"status": "1"}).
+		Union("all", Select("*").From("a").Where(Eq{"status": "2"})).
+		Union("distinct", Select("*").From("a").Where(Eq{"status": "3"})).
+		Union("", Select("*").From("a").Where(Eq{"status": "4"})).
+		ToSQL()
+```
+
+# Conditions
+
+* `Eq` is a redefine of a map, you can give one or more conditions to `Eq`
+
+```Go
+import . "xorm.io/builder"
+
+sql, args, _ := ToSQL(Eq{"a":1})
+// a=? [1]
+sql, args, _ := ToSQL(Eq{"b":"c"}.And(Eq{"c": 0}))
+// b=? AND c=? ["c", 0]
+sql, args, _ := ToSQL(Eq{"b":"c", "c":0})
+// b=? AND c=? ["c", 0]
+sql, args, _ := ToSQL(Eq{"b":"c"}.Or(Eq{"b":"d"}))
+// b=? OR b=? ["c", "d"]
+sql, args, _ := ToSQL(Eq{"b": []string{"c", "d"}})
+// b IN (?,?) ["c", "d"]
+sql, args, _ := ToSQL(Eq{"b": 1, "c":[]int{2, 3}})
+// b=? AND c IN (?,?) [1, 2, 3]
+```
+
+* `Neq` is the same to `Eq`
+
+```Go
+import . "xorm.io/builder"
+
+sql, args, _ := ToSQL(Neq{"a":1})
+// a<>? [1]
+sql, args, _ := ToSQL(Neq{"b":"c"}.And(Neq{"c": 0}))
+// b<>? AND c<>? ["c", 0]
+sql, args, _ := ToSQL(Neq{"b":"c", "c":0})
+// b<>? AND c<>? ["c", 0]
+sql, args, _ := ToSQL(Neq{"b":"c"}.Or(Neq{"b":"d"}))
+// b<>? OR b<>? ["c", "d"]
+sql, args, _ := ToSQL(Neq{"b": []string{"c", "d"}})
+// b NOT IN (?,?) ["c", "d"]
+sql, args, _ := ToSQL(Neq{"b": 1, "c":[]int{2, 3}})
+// b<>? AND c NOT IN (?,?) [1, 2, 3]
+```
+
+* `Gt`, `Gte`, `Lt`, `Lte`
+
+```Go
+import . "xorm.io/builder"
+
+sql, args, _ := ToSQL(Gt{"a", 1}.And(Gte{"b", 2}))
+// a>? AND b>=? [1, 2]
+sql, args, _ := ToSQL(Lt{"a", 1}.Or(Lte{"b", 2}))
+// a<? OR b<=? [1, 2]
+```
+
+* `Like`
+
+```Go
+import . "xorm.io/builder"
+
+sql, args, _ := ToSQL(Like{"a", "c"})
+// a LIKE ? [%c%]
+```
+
+* `Expr` you can customerize your sql with `Expr`
+
+```Go
+import . "xorm.io/builder"
+
+sql, args, _ := ToSQL(Expr("a = ? ", 1))
+// a = ? [1]
+sql, args, _ := ToSQL(Eq{"a": Expr("select id from table where c = ?", 1)})
+// a=(select id from table where c = ?) [1]
+```
+
+* `In` and `NotIn`
+
+```Go
+import . "xorm.io/builder"
+
+sql, args, _ := ToSQL(In("a", 1, 2, 3))
+// a IN (?,?,?) [1,2,3]
+sql, args, _ := ToSQL(In("a", []int{1, 2, 3}))
+// a IN (?,?,?) [1,2,3]
+sql, args, _ := ToSQL(In("a", Expr("select id from b where c = ?", 1))))
+// a IN (select id from b where c = ?) [1]
+```
+
+* `IsNull` and `NotNull`
+
+```Go
+import . "xorm.io/builder"
+
+sql, args, _ := ToSQL(IsNull{"a"})
+// a IS NULL []
+sql, args, _ := ToSQL(NotNull{"b"})
+	// b IS NOT NULL []
+```
+
+* `And(conds ...Cond)`, And can connect one or more condtions via And
+
+```Go
+import . "xorm.io/builder"
+
+sql, args, _ := ToSQL(And(Eq{"a":1}, Like{"b", "c"}, Neq{"d", 2}))
+// a=? AND b LIKE ? AND d<>? [1, %c%, 2]
+```
+
+* `Or(conds ...Cond)`, Or can connect one or more conditions via Or
+
+```Go
+import . "xorm.io/builder"
+
+sql, args, _ := ToSQL(Or(Eq{"a":1}, Like{"b", "c"}, Neq{"d", 2}))
+// a=? OR b LIKE ? OR d<>? [1, %c%, 2]
+sql, args, _ := ToSQL(Or(Eq{"a":1}, And(Like{"b", "c"}, Neq{"d", 2})))
+// a=? OR (b LIKE ? AND d<>?) [1, %c%, 2]
+```
+
+* `Between`
+
+```Go
+import . "xorm.io/builder"
+
+sql, args, _ := ToSQL(Between{"a", 1, 2})
+// a BETWEEN 1 AND 2
+```
+
+* Define yourself conditions
+
+Since `Cond` is an interface.
+
+```Go
+type Cond interface {
+	WriteTo(Writer) error
+	And(...Cond) Cond
+	Or(...Cond) Cond
+	IsValid() bool
+}
+```
+
+You can define yourself conditions and compose with other `Cond`.

+
+Package builder is a simple and powerful sql builder for Go.
+
+Make sure you have installed Go 1.1+ and then:
+
+    go get xorm.io/builder
+
+WARNNING: Currently, only query conditions are supported. Below is the supported conditions.
+
+1. Eq is a redefine of a map, you can give one or more conditions to Eq
+
+    import . "xorm.io/builder"
+
+    sql, args, _ := ToSQL(Eq{"a":1})
+    // a=? [1]
+    sql, args, _ := ToSQL(Eq{"b":"c"}.And(Eq{"c": 0}))
+    // b=? AND c=? ["c", 0]
+    sql, args, _ := ToSQL(Eq{"b":"c", "c":0})
+    // b=? AND c=? ["c", 0]
+    sql, args, _ := ToSQL(Eq{"b":"c"}.Or(Eq{"b":"d"}))
+    // b=? OR b=? ["c", "d"]
+    sql, args, _ := ToSQL(Eq{"b": []string{"c", "d"}})
+    // b IN (?,?) ["c", "d"]
+    sql, args, _ := ToSQL(Eq{"b": 1, "c":[]int{2, 3}})
+    // b=? AND c IN (?,?) [1, 2, 3]
+
+2. Neq is the same to Eq
+
+    import . "xorm.io/builder"
+
+    sql, args, _ := ToSQL(Neq{"a":1})
+    // a<>? [1]
+    sql, args, _ := ToSQL(Neq{"b":"c"}.And(Neq{"c": 0}))
+    // b<>? AND c<>? ["c", 0]
+    sql, args, _ := ToSQL(Neq{"b":"c", "c":0})
+    // b<>? AND c<>? ["c", 0]
+    sql, args, _ := ToSQL(Neq{"b":"c"}.Or(Neq{"b":"d"}))
+    // b<>? OR b<>? ["c", "d"]
+    sql, args, _ := ToSQL(Neq{"b": []string{"c", "d"}})
+    // b NOT IN (?,?) ["c", "d"]
+    sql, args, _ := ToSQL(Neq{"b": 1, "c":[]int{2, 3}})
+    // b<>? AND c NOT IN (?,?) [1, 2, 3]
+
+3. Gt, Gte, Lt, Lte
+
+    import . "xorm.io/builder"
+
+    sql, args, _ := ToSQL(Gt{"a", 1}.And(Gte{"b", 2}))
+    // a>? AND b>=? [1, 2]
+    sql, args, _ := ToSQL(Lt{"a", 1}.Or(Lte{"b", 2}))
+    // a<? OR b<=? [1, 2]
+
+4. Like
+
+    import . "xorm.io/builder"
+
+    sql, args, _ := ToSQL(Like{"a", "c"})
+    // a LIKE ? [%c%]
+
+5. Expr you can customerize your sql with Expr
+
+    import . "xorm.io/builder"
+
+    sql, args, _ := ToSQL(Expr("a = ? ", 1))
+    // a = ? [1]
+    sql, args, _ := ToSQL(Eq{"a": Expr("select id from table where c = ?", 1)})
+    // a=(select id from table where c = ?) [1]
+
+6. In and NotIn
+
+    import . "xorm.io/builder"
+
+    sql, args, _ := ToSQL(In("a", 1, 2, 3))
+    // a IN (?,?,?) [1,2,3]
+    sql, args, _ := ToSQL(In("a", []int{1, 2, 3}))
+    // a IN (?,?,?) [1,2,3]
+    sql, args, _ := ToSQL(In("a", Expr("select id from b where c = ?", 1))))
+    // a IN (select id from b where c = ?) [1]
+
+7. IsNull and NotNull
+
+    import . "xorm.io/builder"
+
+    sql, args, _ := ToSQL(IsNull{"a"})
+    // a IS NULL []
+    sql, args, _ := ToSQL(NotNull{"b"})
+     // b IS NOT NULL []
+
+8. And(conds ...Cond), And can connect one or more condtions via AND
+
+    import . "xorm.io/builder"
+
+    sql, args, _ := ToSQL(And(Eq{"a":1}, Like{"b", "c"}, Neq{"d", 2}))
+    // a=? AND b LIKE ? AND d<>? [1, %c%, 2]
+
+9. Or(conds ...Cond), Or can connect one or more conditions via Or
+
+    import . "xorm.io/builder"
+
+    sql, args, _ := ToSQL(Or(Eq{"a":1}, Like{"b", "c"}, Neq{"d", 2}))
+    // a=? OR b LIKE ? OR d<>? [1, %c%, 2]
+    sql, args, _ := ToSQL(Or(Eq{"a":1}, And(Like{"b", "c"}, Neq{"d", 2})))
+    // a=? OR (b LIKE ? AND d<>?) [1, %c%, 2]
+
+10. Between
+
+    import . "xorm.io/builder"
+
+    sql, args, _ := ToSQL(Between("a", 1, 2))
+    // a BETWEEN 1 AND 2
+
+11. define yourself conditions
+Since Cond is a interface, you can define yourself conditions and compare with them

+## Contributing to xorm
+
+`xorm` has a backlog of [pull requests](https://help.github.com/articles/using-pull-requests), but contributions are still very
+much welcome. You can help with patch review, submitting bug reports,
+or adding new functionality. There is no formal style guide, but
+please conform to the style of existing code and general Go formatting
+conventions when submitting patches.
+
+* [fork a repo](https://help.github.com/articles/fork-a-repo)
+* [creating a pull request ](https://help.github.com/articles/creating-a-pull-request)
+
+### Language
+
+Since `xorm` is a world-wide open source project, please describe your issues or code changes in English as soon as possible.
+
+### Sign your codes with comments
+```
+// !<you github id>! your comments
+
+e.g.,
+
+// !lunny! this is comments made by lunny
+```
+
+### Patch review
+
+Help review existing open [pull requests](https://help.github.com/articles/using-pull-requests) by commenting on the code or
+proposed functionality.
+
+### Bug reports
+
+We appreciate any bug reports, but especially ones with self-contained
+(doesn't depend on code outside of xorm), minimal (can't be simplified
+further) test cases. It's especially helpful if you can submit a pull
+request with just the failing test case(you can find some example test file like [session_get_test.go](https://github.com/go-xorm/xorm/blob/master/session_get_test.go)).
+
+If you implements a new database interface, you maybe need to add a test_<databasename>.sh file.
+For example, [mysql_test.go](https://github.com/go-xorm/xorm/blob/master/test_mysql.sh)
+
+### New functionality
+
+There are a number of pending patches for new functionality, so
+additional feature patches will take a while to merge. Still, patches
+are generally reviewed based on usefulness and complexity in addition
+to time-in-queue, so if you have a knockout idea, take a shot. Feel
+free to open an issue discussion your proposed patch beforehand.

+## Installation
+

+
+## Documents
+
+* [Manual](http://xorm.io/docs)
+
+* [GoDoc](http://godoc.org/github.com/go-xorm/xorm)
+
+## Quick Start
+
+* Create Engine
+
+```Go
+engine, err := xorm.NewEngine(driverName, dataSourceName)
+```
+
+* Define a struct and Sync2 table struct to database
+
+```Go
+type User struct {
+    Id int64
+    Name string
+    Salt string
+    Age int
+    Passwd string `xorm:"varchar(200)"`
+    Created time.Time `xorm:"created"`
+    Updated time.Time `xorm:"updated"`
+}
+
+err := engine.Sync2(new(User))
+```
+
+* Create Engine Group
+
+```Go
+dataSourceNameSlice := []string{masterDataSourceName, slave1DataSourceName, slave2DataSourceName}
+engineGroup, err := xorm.NewEngineGroup(driverName, dataSourceNameSlice)
+```
+
+```Go
+masterEngine, err := xorm.NewEngine(driverName, masterDataSourceName)
+slave1Engine, err := xorm.NewEngine(driverName, slave1DataSourceName)
+slave2Engine, err := xorm.NewEngine(driverName, slave2DataSourceName)
+engineGroup, err := xorm.NewEngineGroup(masterEngine, []*Engine{slave1Engine, slave2Engine})
+```
+
+Then all place where `engine` you can just use `engineGroup`.
+
+* `Query` runs a SQL string, the returned results is `[]map[string][]byte`, `QueryString` returns `[]map[string]string`, `QueryInterface` returns `[]map[string]interface{}`.
+
+```Go
+results, err := engine.Query("select * from user")
+results, err := engine.Where("a = 1").Query()
+
+results, err := engine.QueryString("select * from user")
+results, err := engine.Where("a = 1").QueryString()
+
+results, err := engine.QueryInterface("select * from user")
+results, err := engine.Where("a = 1").QueryInterface()
+```
+
+* `Exec` runs a SQL string, it returns `affected` and `error`
+
+```Go
+affected, err := engine.Exec("update user set age = ? where name = ?", age, name)
+```
+
+* `Insert` one or multiple records to database
+
+```Go
+affected, err := engine.Insert(&user)
+// INSERT INTO struct () values ()
+
+affected, err := engine.Insert(&user1, &user2)
+// INSERT INTO struct1 () values ()
+// INSERT INTO struct2 () values ()
+
+affected, err := engine.Insert(&users)
+// INSERT INTO struct () values (),(),()
+
+affected, err := engine.Insert(&user1, &users)
+// INSERT INTO struct1 () values ()
+// INSERT INTO struct2 () values (),(),()
+```
+
+* `Get` query one record from database
+
+```Go
+has, err := engine.Get(&user)
+// SELECT * FROM user LIMIT 1
+
+has, err := engine.Where("name = ?", name).Desc("id").Get(&user)
+// SELECT * FROM user WHERE name = ? ORDER BY id DESC LIMIT 1
+
+var name string
+has, err := engine.Table(&user).Where("id = ?", id).Cols("name").Get(&name)
+// SELECT name FROM user WHERE id = ?
+
+var id int64
+has, err := engine.Table(&user).Where("name = ?", name).Cols("id").Get(&id)
+has, err := engine.SQL("select id from user").Get(&id)
+// SELECT id FROM user WHERE name = ?
+
+var valuesMap = make(map[string]string)
+has, err := engine.Table(&user).Where("id = ?", id).Get(&valuesMap)
+// SELECT * FROM user WHERE id = ?
+
+var valuesSlice = make([]interface{}, len(cols))
+has, err := engine.Table(&user).Where("id = ?", id).Cols(cols...).Get(&valuesSlice)
+// SELECT col1, col2, col3 FROM user WHERE id = ?
+```
+
+* `Exist` check if one record exist on table
+
+```Go
+has, err := testEngine.Exist(new(RecordExist))
+// SELECT * FROM record_exist LIMIT 1
+
+has, err = testEngine.Exist(&RecordExist{
+		Name: "test1",
+	})
+// SELECT * FROM record_exist WHERE name = ? LIMIT 1
+
+has, err = testEngine.Where("name = ?", "test1").Exist(&RecordExist{})
+// SELECT * FROM record_exist WHERE name = ? LIMIT 1
+
+has, err = testEngine.SQL("select * from record_exist where name = ?", "test1").Exist()
+// select * from record_exist where name = ?
+
+has, err = testEngine.Table("record_exist").Exist()
+// SELECT * FROM record_exist LIMIT 1
+
+has, err = testEngine.Table("record_exist").Where("name = ?", "test1").Exist()
+// SELECT * FROM record_exist WHERE name = ? LIMIT 1
+```
+
+* `Find` query multiple records from database, also you can use join and extends
+
+```Go
+var users []User
+err := engine.Where("name = ?", name).And("age > 10").Limit(10, 0).Find(&users)
+// SELECT * FROM user WHERE name = ? AND age > 10 limit 10 offset 0
+
+type Detail struct {
+    Id int64
+    UserId int64 `xorm:"index"`
+}
+
+type UserDetail struct {
+    User `xorm:"extends"`
+    Detail `xorm:"extends"`
+}
+
+var users []UserDetail
+err := engine.Table("user").Select("user.*, detail.*").
+    Join("INNER", "detail", "detail.user_id = user.id").
+    Where("user.name = ?", name).Limit(10, 0).
+    Find(&users)
+// SELECT user.*, detail.* FROM user INNER JOIN detail WHERE user.name = ? limit 10 offset 0
+```
+
+* `Iterate` and `Rows` query multiple records and record by record handle, there are two methods Iterate and Rows
+
+```Go
+err := engine.Iterate(&User{Name:name}, func(idx int, bean interface{}) error {
+    user := bean.(*User)
+    return nil
+})
+// SELECT * FROM user
+
+err := engine.BufferSize(100).Iterate(&User{Name:name}, func(idx int, bean interface{}) error {
+    user := bean.(*User)
+    return nil
+})
+// SELECT * FROM user Limit 0, 100
+// SELECT * FROM user Limit 101, 100
+
+rows, err := engine.Rows(&User{Name:name})
+// SELECT * FROM user
+defer rows.Close()
+bean := new(Struct)
+for rows.Next() {
+    err = rows.Scan(bean)
+}
+```
+
+* `Update` update one or more records, default will update non-empty and non-zero fields except when you use Cols, AllCols and so on.
+
+```Go
+affected, err := engine.ID(1).Update(&user)
+// UPDATE user SET ... Where id = ?
+
+affected, err := engine.Update(&user, &User{Name:name})
+// UPDATE user SET ... Where name = ?
+
+var ids = []int64{1, 2, 3}
+affected, err := engine.In("id", ids).Update(&user)
+// UPDATE user SET ... Where id IN (?, ?, ?)
+
+// force update indicated columns by Cols
+affected, err := engine.ID(1).Cols("age").Update(&User{Name:name, Age: 12})
+// UPDATE user SET age = ?, updated=? Where id = ?
+
+// force NOT update indicated columns by Omit
+affected, err := engine.ID(1).Omit("name").Update(&User{Name:name, Age: 12})
+// UPDATE user SET age = ?, updated=? Where id = ?
+
+affected, err := engine.ID(1).AllCols().Update(&user)
+// UPDATE user SET name=?,age=?,salt=?,passwd=?,updated=? Where id = ?
+```
+
+* `Delete` delete one or more records, Delete MUST have condition
+
+```Go
+affected, err := engine.Where(...).Delete(&user)
+// DELETE FROM user Where ...
+
+affected, err := engine.ID(2).Delete(&user)
+// DELETE FROM user Where id = ?
+```
+
+* `Count` count records
+
+```Go
+counts, err := engine.Count(&user)
+// SELECT count(*) AS total FROM user
+```
+
+* `Sum` sum functions
+
+```Go
+agesFloat64, err := engine.Sum(&user, "age")
+// SELECT sum(age) AS total FROM user
+
+agesInt64, err := engine.SumInt(&user, "age")
+// SELECT sum(age) AS total FROM user
+
+sumFloat64Slice, err := engine.Sums(&user, "age", "score")
+// SELECT sum(age), sum(score) FROM user
+
+sumInt64Slice, err := engine.SumsInt(&user, "age", "score")
+// SELECT sum(age), sum(score) FROM user
+```
+
+* Query conditions builder
+
+```Go
+err := engine.Where(builder.NotIn("a", 1, 2).And(builder.In("b", "c", "d", "e"))).Find(&users)
+// SELECT id, name ... FROM user WHERE a NOT IN (?, ?) AND b IN (?, ?, ?)
+```
+
+* Multiple operations in one go routine, no transation here but resue session memory
+
+```Go
+session := engine.NewSession()
+defer session.Close()
+
+user1 := Userinfo{Username: "xiaoxiao", Departname: "dev", Alias: "lunny", Created: time.Now()}
+if _, err := session.Insert(&user1); err != nil {
+    return err
+}
+
+user2 := Userinfo{Username: "yyy"}
+if _, err := session.Where("id = ?", 2).Update(&user2); err != nil {
+    return err
+}
+
+if _, err := session.Exec("delete from userinfo where username = ?", user2.Username); err != nil {
+    return err
+}
+
+return nil
+```
+
+* Transation should on one go routine. There is transaction and resue session memory
+
+```Go
+session := engine.NewSession()
+defer session.Close()
+
+// add Begin() before any action
+if err := session.Begin(); err != nil {
+    // if returned then will rollback automatically
+    return err
+}
+
+user1 := Userinfo{Username: "xiaoxiao", Departname: "dev", Alias: "lunny", Created: time.Now()}
+if _, err := session.Insert(&user1); err != nil {
+    return err
+}
+
+user2 := Userinfo{Username: "yyy"}
+if _, err := session.Where("id = ?", 2).Update(&user2); err != nil {
+    return err
+}
+
+if _, err := session.Exec("delete from userinfo where username = ?", user2.Username); err != nil {
+    return err
+}
+
+// add Commit() after all actions
+return session.Commit()
+```
+
+* Or you can use `Transaction` to replace above codes.
+
+```Go
+res, err := engine.Transaction(func(session *xorm.Session) (interface{}, error) {
+    user1 := Userinfo{Username: "xiaoxiao", Departname: "dev", Alias: "lunny", Created: time.Now()}
+    if _, err := session.Insert(&user1); err != nil {
+        return nil, err
+    }
+
+    user2 := Userinfo{Username: "yyy"}
+    if _, err := session.Where("id = ?", 2).Update(&user2); err != nil {
+        return nil, err
+    }
+
+    if _, err := session.Exec("delete from userinfo where username = ?", user2.Username); err != nil {
+        return nil, err
+    }
+    return nil, nil
+})
+```
+
+* Context Cache, if enabled, current query result will be cached on session and be used by next same statement on the same session.
+
+```Go
+	sess := engine.NewSession()
+	defer sess.Close()
+
+	var context = xorm.NewMemoryContextCache()
+
+	var c2 ContextGetStruct
+	has, err := sess.ID(1).ContextCache(context).Get(&c2)
+	assert.NoError(t, err)
+	assert.True(t, has)
+	assert.EqualValues(t, 1, c2.Id)
+	assert.EqualValues(t, "1", c2.Name)
+	sql, args := sess.LastSQL()
+	assert.True(t, len(sql) > 0)
+	assert.True(t, len(args) > 0)
+
+	var c3 ContextGetStruct
+	has, err = sess.ID(1).ContextCache(context).Get(&c3)
+	assert.NoError(t, err)
+	assert.True(t, has)
+	assert.EqualValues(t, 1, c3.Id)
+	assert.EqualValues(t, "1", c3.Name)
+	sql, args = sess.LastSQL()
+	assert.True(t, len(sql) == 0)
+	assert.True(t, len(args) == 0)
+```

+
+# 快速开始
+
+* 第一步创建引擎，driverName, dataSourceName和database/sql接口相同
+
+```Go
+engine, err := xorm.NewEngine(driverName, dataSourceName)
+```
+
+* 定义一个和表同步的结构体，并且自动同步结构体到数据库
+
+```Go
+type User struct {
+    Id int64
+    Name string
+    Salt string
+    Age int
+    Passwd string `xorm:"varchar(200)"`
+    Created time.Time `xorm:"created"`
+    Updated time.Time `xorm:"updated"`
+}
+
+err := engine.Sync2(new(User))
+```
+
+* 创建Engine组
+
+```Go
+dataSourceNameSlice := []string{masterDataSourceName, slave1DataSourceName, slave2DataSourceName}
+engineGroup, err := xorm.NewEngineGroup(driverName, dataSourceNameSlice)
+```
+
+```Go
+masterEngine, err := xorm.NewEngine(driverName, masterDataSourceName)
+slave1Engine, err := xorm.NewEngine(driverName, slave1DataSourceName)
+slave2Engine, err := xorm.NewEngine(driverName, slave2DataSourceName)
+engineGroup, err := xorm.NewEngineGroup(masterEngine, []*Engine{slave1Engine, slave2Engine})
+```
+
+所有使用 `engine` 都可以简单的用 `engineGroup` 来替换。
+
+* `Query` 最原始的也支持SQL语句查询，返回的结果类型为 []map[string][]byte。`QueryString` 返回 []map[string]string, `QueryInterface` 返回 `[]map[string]interface{}`.
+
+```Go
+results, err := engine.Query("select * from user")
+results, err := engine.Where("a = 1").Query()
+
+results, err := engine.QueryString("select * from user")
+results, err := engine.Where("a = 1").QueryString()
+
+results, err := engine.QueryInterface("select * from user")
+results, err := engine.Where("a = 1").QueryInterface()
+```
+
+* `Exec` 执行一个SQL语句
+
+```Go
+affected, err := engine.Exec("update user set age = ? where name = ?", age, name)
+```
+
+* `Insert` 插入一条或者多条记录
+
+```Go
+affected, err := engine.Insert(&user)
+// INSERT INTO struct () values ()
+
+affected, err := engine.Insert(&user1, &user2)
+// INSERT INTO struct1 () values ()
+// INSERT INTO struct2 () values ()
+
+affected, err := engine.Insert(&users)
+// INSERT INTO struct () values (),(),()
+
+affected, err := engine.Insert(&user1, &users)
+// INSERT INTO struct1 () values ()
+// INSERT INTO struct2 () values (),(),()
+```
+
+* `Get` 查询单条记录
+
+```Go
+has, err := engine.Get(&user)
+// SELECT * FROM user LIMIT 1
+
+has, err := engine.Where("name = ?", name).Desc("id").Get(&user)
+// SELECT * FROM user WHERE name = ? ORDER BY id DESC LIMIT 1
+
+var name string
+has, err := engine.Table(&user).Where("id = ?", id).Cols("name").Get(&name)
+// SELECT name FROM user WHERE id = ?
+
+var id int64
+has, err := engine.Table(&user).Where("name = ?", name).Cols("id").Get(&id)
+has, err := engine.SQL("select id from user").Get(&id)
+// SELECT id FROM user WHERE name = ?
+
+var valuesMap = make(map[string]string)
+has, err := engine.Table(&user).Where("id = ?", id).Get(&valuesMap)
+// SELECT * FROM user WHERE id = ?
+
+var valuesSlice = make([]interface{}, len(cols))
+has, err := engine.Table(&user).Where("id = ?", id).Cols(cols...).Get(&valuesSlice)
+// SELECT col1, col2, col3 FROM user WHERE id = ?
+```
+
+* `Exist` 检测记录是否存在
+
+```Go
+has, err := testEngine.Exist(new(RecordExist))
+// SELECT * FROM record_exist LIMIT 1
+
+has, err = testEngine.Exist(&RecordExist{
+		Name: "test1",
+	})
+// SELECT * FROM record_exist WHERE name = ? LIMIT 1
+
+has, err = testEngine.Where("name = ?", "test1").Exist(&RecordExist{})
+// SELECT * FROM record_exist WHERE name = ? LIMIT 1
+
+has, err = testEngine.SQL("select * from record_exist where name = ?", "test1").Exist()
+// select * from record_exist where name = ?
+
+has, err = testEngine.Table("record_exist").Exist()
+// SELECT * FROM record_exist LIMIT 1
+
+has, err = testEngine.Table("record_exist").Where("name = ?", "test1").Exist()
+// SELECT * FROM record_exist WHERE name = ? LIMIT 1
+```
+
+* `Find` 查询多条记录，当然可以使用Join和extends来组合使用
+
+```Go
+var users []User
+err := engine.Where("name = ?", name).And("age > 10").Limit(10, 0).Find(&users)
+// SELECT * FROM user WHERE name = ? AND age > 10 limit 10 offset 0
+
+type Detail struct {
+    Id int64
+    UserId int64 `xorm:"index"`
+}
+
+type UserDetail struct {
+    User `xorm:"extends"`
+    Detail `xorm:"extends"`
+}
+
+var users []UserDetail
+err := engine.Table("user").Select("user.*, detail.*")
+    Join("INNER", "detail", "detail.user_id = user.id").
+    Where("user.name = ?", name).Limit(10, 0).
+    Find(&users)
+// SELECT user.*, detail.* FROM user INNER JOIN detail WHERE user.name = ? limit 10 offset 0
+```
+
+* `Iterate` 和 `Rows` 根据条件遍历数据库，可以有两种方式: Iterate and Rows
+
+```Go
+err := engine.Iterate(&User{Name:name}, func(idx int, bean interface{}) error {
+    user := bean.(*User)
+    return nil
+})
+// SELECT * FROM user
+
+err := engine.BufferSize(100).Iterate(&User{Name:name}, func(idx int, bean interface{}) error {
+    user := bean.(*User)
+    return nil
+})
+// SELECT * FROM user Limit 0, 100
+// SELECT * FROM user Limit 101, 100
+
+rows, err := engine.Rows(&User{Name:name})
+// SELECT * FROM user
+defer rows.Close()
+bean := new(Struct)
+for rows.Next() {
+    err = rows.Scan(bean)
+}
+```
+
+* `Update` 更新数据，除非使用Cols,AllCols函数指明，默认只更新非空和非0的字段
+
+```Go
+affected, err := engine.ID(1).Update(&user)
+// UPDATE user SET ... Where id = ?
+
+affected, err := engine.Update(&user, &User{Name:name})
+// UPDATE user SET ... Where name = ?
+
+var ids = []int64{1, 2, 3}
+affected, err := engine.In(ids).Update(&user)
+// UPDATE user SET ... Where id IN (?, ?, ?)
+
+// force update indicated columns by Cols
+affected, err := engine.ID(1).Cols("age").Update(&User{Name:name, Age: 12})
+// UPDATE user SET age = ?, updated=? Where id = ?
+
+// force NOT update indicated columns by Omit
+affected, err := engine.ID(1).Omit("name").Update(&User{Name:name, Age: 12})
+// UPDATE user SET age = ?, updated=? Where id = ?
+
+affected, err := engine.ID(1).AllCols().Update(&user)
+// UPDATE user SET name=?,age=?,salt=?,passwd=?,updated=? Where id = ?
+```
+
+* `Delete` 删除记录，需要注意，删除必须至少有一个条件，否则会报错。要清空数据库可以用EmptyTable
+
+```Go
+affected, err := engine.Where(...).Delete(&user)
+// DELETE FROM user Where ...
+
+affected, err := engine.ID(2).Delete(&user)
+// DELETE FROM user Where id = ?
+```
+
+* `Count` 获取记录条数
+
+```Go
+counts, err := engine.Count(&user)
+// SELECT count(*) AS total FROM user
+```
+
+* `Sum` 求和函数
+
+```Go
+agesFloat64, err := engine.Sum(&user, "age")
+// SELECT sum(age) AS total FROM user
+
+agesInt64, err := engine.SumInt(&user, "age")
+// SELECT sum(age) AS total FROM user
+
+sumFloat64Slice, err := engine.Sums(&user, "age", "score")
+// SELECT sum(age), sum(score) FROM user
+
+sumInt64Slice, err := engine.SumsInt(&user, "age", "score")
+// SELECT sum(age), sum(score) FROM user
+```
+
+* 条件编辑器
+
+```Go
+err := engine.Where(builder.NotIn("a", 1, 2).And(builder.In("b", "c", "d", "e"))).Find(&users)
+// SELECT id, name ... FROM user WHERE a NOT IN (?, ?) AND b IN (?, ?, ?)
+```
+
+* 在一个Go程中多次操作数据库，但没有事务
+
+```Go
+session := engine.NewSession()
+defer session.Close()
+
+user1 := Userinfo{Username: "xiaoxiao", Departname: "dev", Alias: "lunny", Created: time.Now()}
+if _, err := session.Insert(&user1); err != nil {
+    return err
+}
+
+user2 := Userinfo{Username: "yyy"}
+if _, err := session.Where("id = ?", 2).Update(&user2); err != nil {
+    return err
+}
+
+if _, err := session.Exec("delete from userinfo where username = ?", user2.Username); err != nil {
+    return err
+}
+
+return nil
+```
+
+* 在一个Go程中有事务
+
+```Go
+session := engine.NewSession()
+defer session.Close()

+
+* 事务的简写方法
+
+```Go
+res, err := engine.Transaction(func(session *xorm.Session) (interface{}, error) {
+    user1 := Userinfo{Username: "xiaoxiao", Departname: "dev", Alias: "lunny", Created: time.Now()}
+    if _, err := session.Insert(&user1); err != nil {
+        return nil, err
+    }
+
+    user2 := Userinfo{Username: "yyy"}
+    if _, err := session.Where("id = ?", 2).Update(&user2); err != nil {
+        return nil, err
+    }
+
+    if _, err := session.Exec("delete from userinfo where username = ?", user2.Username); err != nil {
+        return nil, err
+    }
+    return nil, nil
+})
+```
+
+* 上下文缓存，如果启用，那么针对单个对象的查询将会被缓存到系统中，可以被下一个查询使用。
+
+```Go
+	sess := engine.NewSession()
+	defer sess.Close()
+
+	var context = xorm.NewMemoryContextCache()
+
+	var c2 ContextGetStruct
+	has, err := sess.ID(1).ContextCache(context).Get(&c2)
+	assert.NoError(t, err)
+	assert.True(t, has)
+	assert.EqualValues(t, 1, c2.Id)
+	assert.EqualValues(t, "1", c2.Name)
+	sql, args := sess.LastSQL()
+	assert.True(t, len(sql) > 0)
+	assert.True(t, len(args) > 0)
+

+
+Package xorm is a simple and powerful ORM for Go.
+
+Installation
+
+Make sure you have installed Go 1.6+ and then:
+
+    go get github.com/go-xorm/xorm
+
+Create Engine
+
+Firstly, we should new an engine for a database
+
+    engine, err := xorm.NewEngine(driverName, dataSourceName)
+
+Method NewEngine's parameters is the same as sql.Open. It depends
+drivers' implementation.
+Generally, one engine for an application is enough. You can set it as package variable.
+
+Raw Methods
+
+XORM also support raw SQL execution:
+
+1. query a SQL string, the returned results is []map[string][]byte
+
+    results, err := engine.Query("select * from user")
+
+2. execute a SQL string, the returned results
+
+    affected, err := engine.Exec("update user set .... where ...")
+
+ORM Methods
+
+There are 8 major ORM methods and many helpful methods to use to operate database.
+
+1. Insert one or multiple records to database
+
+    affected, err := engine.Insert(&struct)
+    // INSERT INTO struct () values ()
+    affected, err := engine.Insert(&struct1, &struct2)
+    // INSERT INTO struct1 () values ()
+    // INSERT INTO struct2 () values ()
+    affected, err := engine.Insert(&sliceOfStruct)
+    // INSERT INTO struct () values (),(),()
+    affected, err := engine.Insert(&struct1, &sliceOfStruct2)
+    // INSERT INTO struct1 () values ()
+    // INSERT INTO struct2 () values (),(),()
+
+2. Query one record or one variable from database
+
+    has, err := engine.Get(&user)
+    // SELECT * FROM user LIMIT 1
+
+    var id int64
+    has, err := engine.Table("user").Where("name = ?", name).Get(&id)
+    // SELECT id FROM user WHERE name = ? LIMIT 1
+
+3. Query multiple records from database
+
+    var sliceOfStructs []Struct
+    err := engine.Find(&sliceOfStructs)
+    // SELECT * FROM user
+
+    var mapOfStructs = make(map[int64]Struct)
+    err := engine.Find(&mapOfStructs)
+    // SELECT * FROM user
+
+    var int64s []int64
+    err := engine.Table("user").Cols("id").Find(&int64s)
+    // SELECT id FROM user
+
+4. Query multiple records and record by record handle, there two methods, one is Iterate,
+another is Rows
+
+    err := engine.Iterate(...)
+    // SELECT * FROM user
+
+    rows, err := engine.Rows(...)
+    // SELECT * FROM user
+    defer rows.Close()
+    bean := new(Struct)
+    for rows.Next() {
+        err = rows.Scan(bean)
+    }
+
+5. Update one or more records
+
+    affected, err := engine.ID(...).Update(&user)
+    // UPDATE user SET ...
+
+6. Delete one or more records, Delete MUST has condition
+
+    affected, err := engine.Where(...).Delete(&user)
+    // DELETE FROM user Where ...
+
+7. Count records
+
+    counts, err := engine.Count(&user)
+    // SELECT count(*) AS total FROM user
+
+    counts, err := engine.SQL("select count(*) FROM user").Count()
+    // select count(*) FROM user
+
+8. Sum records
+
+    sumFloat64, err := engine.Sum(&user, "id")
+    // SELECT sum(id) from user
+
+    sumFloat64s, err := engine.Sums(&user, "id1", "id2")
+    // SELECT sum(id1), sum(id2) from user
+
+    sumInt64s, err := engine.SumsInt(&user, "id1", "id2")
+    // SELECT sum(id1), sum(id2) from user
+
+Conditions
+
+The above 8 methods could use with condition methods chainable.
+Attention: the above 8 methods should be the last chainable method.
+
+1. ID, In
+
+    engine.ID(1).Get(&user) // for single primary key
+    // SELECT * FROM user WHERE id = 1
+    engine.ID(core.PK{1, 2}).Get(&user) // for composite primary keys
+    // SELECT * FROM user WHERE id1 = 1 AND id2 = 2
+    engine.In("id", 1, 2, 3).Find(&users)
+    // SELECT * FROM user WHERE id IN (1, 2, 3)
+    engine.In("id", []int{1, 2, 3}).Find(&users)
+    // SELECT * FROM user WHERE id IN (1, 2, 3)
+
+2. Where, And, Or
+
+    engine.Where().And().Or().Find()
+    // SELECT * FROM user WHERE (.. AND ..) OR ...
+
+3. OrderBy, Asc, Desc
+
+    engine.Asc().Desc().Find()
+    // SELECT * FROM user ORDER BY .. ASC, .. DESC
+    engine.OrderBy().Find()
+    // SELECT * FROM user ORDER BY ..
+
+4. Limit, Top
+
+    engine.Limit().Find()
+    // SELECT * FROM user LIMIT .. OFFSET ..
+    engine.Top(5).Find()
+    // SELECT TOP 5 * FROM user // for mssql
+    // SELECT * FROM user LIMIT .. OFFSET 0 //for other databases
+
+5. SQL, let you custom SQL
+
+    var users []User
+    engine.SQL("select * from user").Find(&users)
+
+6. Cols, Omit, Distinct
+
+    var users []*User
+    engine.Cols("col1, col2").Find(&users)
+    // SELECT col1, col2 FROM user
+    engine.Cols("col1", "col2").Where().Update(user)
+    // UPDATE user set col1 = ?, col2 = ? Where ...
+    engine.Omit("col1").Find(&users)
+    // SELECT col2, col3 FROM user
+    engine.Omit("col1").Insert(&user)
+    // INSERT INTO table (non-col1) VALUES ()
+    engine.Distinct("col1").Find(&users)
+    // SELECT DISTINCT col1 FROM user
+
+7. Join, GroupBy, Having
+
+    engine.GroupBy("name").Having("name='xlw'").Find(&users)
+    //SELECT * FROM user GROUP BY name HAVING name='xlw'
+    engine.Join("LEFT", "userdetail", "user.id=userdetail.id").Find(&users)
+    //SELECT * FROM user LEFT JOIN userdetail ON user.id=userdetail.id
