安装驱动

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

import ("database/sql""fmt"_ "github.com/go-sql-driver/mysql"
)

连接数据库

	//用户名：密码^@tcp(地址:3306)/数据库db, err := sql.Open("mysql", "root:123456%^@tcp(39.107.87.114:3306)/book_manager?charset=utf8")if err!=nil {fmt.Println(err)return}   

查询表

	//表结构type info struct {id int `db:"id"`name string `db:"name"`author string `db:"author"`}   //查询表rows,err:=db.Query("SELECT * FROM book")//遍历打印for rows.Next(){var s infoerr=rows.Scan(&s.id,&s.name,&s.author,)fmt.Println(s)}//用完关闭rows.Close()
