go，sqlx使用mysql

package mainimport ("fmt"_ "github.com/go-sql-driver/mysql""github.com/jmoiron/sqlx"
)var Db *sqlx.DBtype Dade1 struct {Id   intDade stringDada string
}// 初始化数据库连接
func init() {database, err := sqlx.Open("mysql", "root:root@tcp(localhost:3306)/dade2")if err != nil {fmt.Println("连接失败,", err)panic("连接失败")}// 连接成功后，可以进行数据库操作fmt.Println("连接成功")Db = database
}func main() {var dade []Dade1err := Db.Select(&dade, "select * from dade1 where id=?", 1)if err != nil {fmt.Println("查询失败, ", err)return}fmt.Println(dade)
}
