type Conn struct {
	*sql.DB
}

func Open(host string, port int, user string, passwd string, dbname string) (db Conn, err error)

Open(主机地址，端口号(int)，用户名，密码，数据库名) 自带Ping()尝试连接数据库

func (db *Conn) Close() (err error)

可能会用到的Close 直接调用DB.Close()，未做处理。

func (db *Conn) Exec(sql string, args ...any) (sql.Result, error)

直接调用的DB.Exec，未做处理。 TODO 考虑将返回改为仅error，考虑因素，是否有时会使用到sql.Result

func (db *Conn) Query(sql string, args ...any) (result []map[string]any, err error)

Query返回一个map[string]any的切片，[]byte已经转为string

func (db *Conn) QueryRow(sql string, args ...any) (result map[string]any, err error)

同Query，仅返回第一行结果。
