# sqlext

sqlext use to extend [gorm](https://github.com/jinzhu/gorm) and [gocql](https://github.com/gocql/gocql)

- gorm not support batch insert，`BatchInsert` is a universal batch insert API.

- gocql not support bind querying data to struct，`MapToStruct` fill struct fields with map value

## example

- BatchInsert  

```go

type GroupMember struct {

	ID        int64

	GroupID   int64

	Type      int8

	Extra     []byte

	JoinTime  time.Time

}

var mydb *gorm.DB

var members = []GroupMember{}

sqlext.BatchInsert(mydb.DB(),members)

//generated SQL: INSERT INTO group_member (id, group_id, type, extra, join_time) VALUES (?,?,?,?,?), (?,?,?,?,?) ...

```

- MapToStruct

```go

// MapToStruct

func GetUsersByIDs(userIDs []int64) (users []User, err error) {

	iter := Cassandra.Query("SELECT * FROM user WHERE id IN ?", userIDs).Iter()

	for {

		row := make(map[string]interface{})

		if !iter.MapScan(row) {

			break

		}

		user := User{}

		err = sqlext.MapToStruct(row, &user)

		if err != nil {

			return nil, err

		}

		users = append(users, user)

	}

	return users, nil

}

```
