在golang中操作mysql数据库的实现代码

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

CREATE TABLE IF NOT EXISTS `test`.`user` (
 `user_id` INT(11) UNSIGNED NOT NULL AUTO_INCREMENT COMMENT '用户编号',
 `user_name` VARCHAR(45) NOT NULL COMMENT '用户名称',
 `user_age` TINYINT(3) UNSIGNED NOT NULL DEFAULT 0 COMMENT '用户年龄',
 `user_sex` TINYINT(3) UNSIGNED NOT NULL DEFAULT 0 COMMENT '用户性别',
 PRIMARY KEY (`user_id`))
 ENGINE = InnoDB
 AUTO_INCREMENT = 1
 DEFAULT CHARACTER SET = utf8
 COLLATE = utf8_general_ci
 COMMENT = '用户表'

package main
import (
 "fmt"
 "database/sql"
 //导入mysql的驱动
 _ "github.com/go-sql-driver/mysql" 
)
func main(){
 //使用database/sql包中的Open连接数据库
 db,err := sql.Open("mysql","root:root@tcp(localhost:3306)/test?charset=utf8")
 if err != nil {
 fmt.Println("连接数据库失败:",err)
 return 
 }
 //使用DB结构体实例方法Prepare预处理插入,Prepare会返回一个stmt对象
 stmt,err := db.Prepare("insert into `user`(user_name,user_age,user_sex)values(?,?,?)")
 if err!=nil{
 fmt.Println("预处理失败:",err)
 return  
 }
 //使用Stmt对象执行预处理参数
 result,err := stmt.Exec("pengjin",33,"男")
 if err!=nil{
 fmt.Println("执行预处理失败:",err)
 return  
 }else{
 rows,_ := result.RowsAffected()
 fmt.Println("执行成功,影响行数",rows,"行" )
 }
}
