Xorm is a simple and powerful ORM for Go.
Struct <-> Table Mapping Support
Chainable APIs
Transaction Support
Both ORM and raw SQL operation Support
Sync database schema Support
Query Cache speed up
Database Reverse support, See Xorm Tool README
Simple cascade loading support
Optimistic Locking support
SQL Builder support via github.com/go-xorm/builder
Automatical Read/Write seperatelly
Drivers for Go's sql package which currently support database/sql includes:
MyMysql: github.com/ziutek/mymysql/godrv
Postgres: github.com/lib/pq
Tidb: github.com/pingcap/tidb
SQLite: github.com/mattn/go-sqlite3
Oracle: github.com/mattn/go-oci8 (experiment)

go get github.com/go-xorm/xorm
engine, err := xorm.NewEngine(driverName, dataSourceName)
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))
dataSourceNameSlice := []string{masterDataSourceName, slave1DataSourceName, slave2DataSourceName}
engineGroup, err := xorm.NewEngineGroup(driverName, dataSourceNameSlice)
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{}
.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
affected, err := engine.Exec("update user set age = ? where name = ?", age, name)
Insert
one or multiple records to databaseaffected, 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 databasehas, 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.Where("id = ?", id).Cols("name").Get(&name)
// SELECT name FROM user WHERE id = ?
var id int64
has, err := engine.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.Where("id = ?", id).Get(&valuesMap)
// SELECT * FROM user WHERE id = ?
var valuesSlice = make([]interface{}, len(cols))
has, err := engine.Where("id = ?", id).Cols(cols...).Get(&valuesSlice)
// SELECT col1, col2, col3 FROM user WHERE id = ?
Exist
check if one record exist on tablehas, 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 extendsvar 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 Rowserr := 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.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 conditionaffected, err := engine.Where(...).Delete(&user)
// DELETE FROM user Where ...
affected, err := engine.ID(2).Delete(&user)
// DELETE FROM user Where id = ?
Count
count recordscounts, err := engine.Count(&user)
// SELECT count(*) AS total FROM user
Sum
sum functionsagesFloat64, 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
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 (?, ?, ?)
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
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()
