Go语言连接MySQL和SQL Server

1 连接MySQL

先获取第三方包

go get -u github.com/go-sql-driver/mysql

代码如下

package main

import (
	"database/sql"
	"fmt"

	_ "github.com/go-sql-driver/mysql"
)

const (
	userName = "rsq"
	password = "123456"
	ip = "192.168.1.100"
	port = "3306"
	dbName = "test"
)
func connInsert(BillMonth string, BusinessCodeName string, RealTotalCost float64) {

	// 构建连接："用户名:密码@tcp(IP:端口)/数据库?charset=utf8"
	dbInfo := strings.Join([]string{userName, ":", password, "@tcp(",ip, ":", port, ")/", dbName, "?charset=utf8"}, "")

	// 打开数据库,前者是驱动名，所以要导入： _ "github.com/go-sql-driver/mysql"
	db, err := sql.Open("mysql", dbInfo)
	if err != nil {
		fmt.Println("Open database Error:", err)
	}

	// 插入操作
	insert, err := db.Exec("INSERT INTO student (Name,Age,Score) VALUES (?, ?, ?)", "tom", 18, 88.5)
	if err != nil {
		fmt.Println("Insert data err=", err)
	}
	id, err := insert.LastInsertId()
	fmt.Printf("成功插入, id是%v\n", id)

}

2 连接SQL Server

获取第三方包

go get github.com/mattn/go-adodb

# 安装以下包，不然报错 cannot find package "golang.org/x/sys/unix"
mkdir -p $GOPATH/src/golang.org/x
cd $GOPATH/src/golang.org/x
git clone https://github.com/golang/sys.git
git clone https://github.com/golang/net.git

# windows下直接去github获取zip包，解压放到 $GOPATH/src/golang.org/x/目录 即可

代码如下

package main

import (
	"database/sql"
	"fmt"

	_ "github.com/mattn/go-adodb"
)

func TestSqlServer(BillMonth string, BusinessCodeName string, RealTotalCost float64) {
	var conf []string
	var db *sql.DB
	var err error
	conf = append(conf, "Provider=SQLOLEDB")
	conf = append(conf, "Data Source=192.168.1.100")  // sqlserver IP 和 服务器名称
	conf = append(conf, "Initial Catalog=test") // 数据库名
	conf = append(conf, "user id=rsq") // 登陆用户名
	conf = append(conf, "password=123456")  // 登陆密码
	//fmt.Println(strings.Join(conf, ";"))
	
	// 连接数据库
	db, err = sql.Open("adodb", strings.Join(conf, ";"))
	if err != nil {
		fmt.Println("sql open:", err)
		return
	}

	// 插入数据
	insert, err := db.Exec("INSERT INTO student (Name,Age,Score) VALUES (?, ?, ?)", "tom", 18, 88.5)
	if err != nil {
		fmt.Println("Insert data err=", err)
	}
	fmt.Println("成功插入数据!")

}
