存储过程插入查询

Question

这是我的代码。

CREATE PROCEDURE add_new_user(IN VARCHAR(30) UName)
BEGIN
INSERT INTO `tbl_user_details` (`Name`) VALUES(UName);
END

我运行此查询时显示错误

错误代码：1064 您的SQL语法有误；检查与您的MariaDB服务器版本相对应的手册以获取正确的语法，以在第1行的“ END”附近使用

请给我更正。

如果该过程中只有1条语句，则无需设置定界符或使用begin..end语句。

MariaDB [sandbox]> drop procedure if exists p;
Query OK, 0 rows affected (0.00 sec)

MariaDB [sandbox]> CREATE PROCEDURE p(IN UName VARCHAR(30) )
    -> INSERT INTO `tbl_user_details` (`Name`) VALUES(UName);
Query OK, 0 rows affected (0.00 sec)

MariaDB [sandbox]> show create procedure p;
