MySQL driver(驱动) liblbmysql for Go1

浏览:905次出处信息

Go语言1.0出来之后,原来可用的MySQL驱动在新版本上基本不可用了,于是这几天自己写了个简单的MySQL的驱动,暂不支持prepare,没有implement sql/driver.　或许有能用的上的朋友,所以分享出来.　先介绍用法,后面提供下载链接.
先直接上例子

package main

import (
"log"
"liblbmysql"
)

func main() {
settings := make(map[string]interface{})

settings["host"] = "localhost"
settings["port"] = 3306
settings["uname"] = "ivan"
settings["pass"] = "******"
settings["dbname"] = "test"
settings["charset"] = "utf8"

conn, err := liblbmysql.Connect(settings)
if err != nil {
log.Fatal("Connect to MySQL error: %v", err)
}

var qr *liblbmysql.QueryResult

qr, err = conn.ExecuteFetch("select * from ivan")
if err != nil {
log.Printf("query error: %v", err)
} else {
for {
m := qr.FetchMap()
if m != nil {
log.Printf("row map: %v\n", m)
} else {
break
}
}
}
qr.Free()
conn.Close()
}

库名: package liblbmysql, 因此将　liblbmysql.a 保存到对应的pkg目录下,然后　import(“liblbmysql”)即可引入该mysql驱动
连接MySQL配置参数:　类型:map[string]interface{}, 可配置的参数有host, port, unix_socket, uname, pass, dbname, charset 分别对应MySQL数据库的ip, 端口, unix socoket, 用户名,密码,初始化数据库,连接字符集.

相关方法\结果集\字段\记录等的类型定义:

type QueryResult struct {
Fields []Field
RowsAffected uint64
InsertId uint64
Rows [][]interface{}
…
}

type Field struct {
Name string
Type int64
…
}

func Connect(info map[string]interface{}) (conn *Connection, err error)

func (this *Connection) Begin() (err error)

func (this *Connection) Commit() (err error)

func (this *Connection) Rollback() (err error)

func (this *Connection) ExecuteFetch(query string) (qr *QueryResult, err error)

func (qr *QueryResult) FetchRow() []interface{}

func (qr *QueryResult) FetchRows() [][]interface{}

func (qr *QueryResult) FetchMap() map[string]interface{}

func (qr *QueryResult) Free()
