+
+### 1. Retrieving instance
+```go
+db := g.DB()

+```
+### 2. Chaining Operations
+
+`Where + string`
+```go
+// SELECT * FROM user WHERE uid>1 LIMIT 0,10
+r, err := db.Table("user").Where("uid > ?", 1).Limit(0, 10).Select()
+
+// SELECT uid,name FROM user WHERE uid>1 LIMIT 0,10

+// SELECT * FROM user WHERE (uid=1) OR (name='john')
+r, err := db.Table("user").Where("uid=?", 1).Or("name=?", "john").One()
+```
+`Where + map`
+```go
+// SELECT * FROM user WHERE uid=1 AND name='john'
+r, err := db.Table("user").Where(g.Map{"uid" : 1, "name" : "john"}).One()
+// SELECT * FROM user WHERE uid=1 AND age>18
+r, err := db.Table("user").Where(g.Map{"uid" : 1, "age>" : 18}).One()
+```
+`Where + struct/*struct`
+```go
+type User struct {
+    Id       int    `json:"uid"`
+    UserName string `gconv:"name"`
+}
+// SELECT * FROM user WHERE uid =1 AND name='john'
+r, err := db.Table("user").Where(User{ Id : 1, UserName : "john"}).One()
+// SELECT * FROM user WHERE uid =1
+r, err := db.Table("user").Where(&User{ Id : 1}).One()
+```
+### 3. Update & Delete
+```go
+// UPDATE user SET name='john guo' WHERE name='john'
+r, err := db.Table("user").Data(gdb.Map{"name" : "john guo"}).Where("name=?", "john").Update()
+r, err := db.Table("user").Data("name='john guo'").Where("name=?", "john").Update()
+// UPDATE user SET status=1 ORDER BY login_time asc LIMIT 10
+r, err := db.Table("user").Data("status", 1).OrderBy("login_time asc").Limit(10).Update
+
+// DELETE FROM user WHERE uid=10
+r, err := db.Table("user").Where("uid=?", 10).Delete()
+// DELETE FROM user ORDER BY login_time asc LIMIT 10
+r, err := db.Table("user").OrderBy("login_time asc").Limit(10).Delete()
+```
+### 4. Insert & Replace & Save
+```go
+r, err := db.Table("user").Data(g.Map{"name": "john"}).Insert()
+r, err := db.Table("user").Data(g.Map{"uid": 10000, "name": "john"}).Replace()
+r, err := db.Table("user").Data(g.Map{"uid": 10001, "name": "john"}).Save()
+```
+### 5. Transaction
+```go
+if tx, err := db.Begin(); err == nil {
+    r, err := tx.Save("user", g.Map{
+        "uid"  :  1,
+        "name" : "john",
+    })
+    tx.Commit()
+}
+```
+### 6. Error Handling
+```go
+func GetOrderInfo(id int) (order *Order, err error) {
+    err = g.DB().Table("order").Where("id", id).Struct(&order)
+    if err != nil && err == sql.ErrNoRows {
+        err = nil
+    }
+    return
+}
+```
