mysql 里面有go的用法吗

mysql不像 SQL Server，写一段SQL，要go了才执行，默认 分号就执行了。

在网上找了一大堆例子，最后简化一下把，一下会从安装mysql开始，与大家分享一下如何用go链接服务器上的mysql

我用的是ubuntu系统

1，安装mysql：sudo apt-get install mysql-server （记住root的密码假设密码为root123）

2，进入mysql：mysql -uroot -p 然后输入密码

3，创建一个数据库：create database people

4，给数据库people添加用户：GRANT ALL PRIVILEGES ON people.* TO peo@localhost IDENTIFIED BY "peo123"

5,调整数据库配置以便于远程访问：GRANT ALL PRIVILEGES ON people.* TO peo@“%” IDENTIFIED BY "peo123"然后推出mysql执行：sudo nano /etc/mysql/my.cnf

修改bind-address=127.0.0.1 到bind-address= 机器的IP（就是安装mysql的机器的ip）

6，重启mysql：sudo /etc/init.d/mysql restart

7,建表：首先进入mysql：mysql -u peo -p

进入数据库下：use people

创建表：create table hello(age int, name varchar(10))

插入一条数据：insert into hello(age, name) values(19, "hello world")

至此数据库方面的工作已经做好，接下来是go语言了

8，首先下载mysql的驱动包（应该是这样叫）执行 go get github.com/go-sql-driver/mysql代码会下载到你的gopath下（执行export可以查看gopath）

接着就是下面的代码了

package main

import "database/sql"

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

import "encoding/json"

import "fmt"

type User struct {

Age int `json:"age"`

Name string `json:"name"`

}

func main() {

fmt.Println("start")

db, err := sql.Open("mysql", "peo:peo123@tcp(192.168.0.58:3306)/people?charset=utf8")

if err != nil {

panic(err)

}

rows, err := db.Query("select age,name from hello")

if err != nil {

panic(err)

}

defer rows.Close()

for rows.Next() {

user := &User{}

err = rows.Scan(&user.Age, &user.Name)

if err != nil {

painc(err)

}

b, _ := json.Marshal(user)

fmt.Println(string(b))

}

println("end")

}

至此结束

直接将数据库表名字段作为字符类型传到存储过程中，存储过程拼接sql语句，再用exec执行。例如：CREATE PROCEDURE [proc_test](@tablename varchar(100))WITH EXECUTE AS CALLERASdeclare @sql varchar(1000)set @sql='select * from '+@tablenameexec(@sql)GO再直接执行 exec proc_test '学生表'

在MYSQL里面执行SQL脚本的命令是source，比如你调用当前目录demo.sql的命令是：

mysql>source demo.sql

注意，mysql>是系统自动出现的提示符。在mysql>下输入?可以显示所有你可以使用的命令，利用软件本身的帮助功能，你可以学习许多知识。

mysql>?
