使用 Procedure with Loop 删除 SQL 中的记录

Question

我正在尝试使用 SQL 的 DELETE 过程从数据库中删除 1000 万条记录以及更多记录。我想删除循环中的记录，就像每个交互记录一样，应该像下面这样删除 1。

drop procedure if exists PROC_WEEKLY_TASK_DELETE;
DELIMITER //
CREATE DEFINER=`root`@`localhost` PROCEDURE `PROC_WEEKLY_TASK_DELETE`()
BEGIN

set @rows = (select count(*) from MY_TABLE where IS_VALID_DATE='false');
set @a = 0;
while(@a<@rows)
do delete from MY_TABLE where IS_VALID_DATE='false' limit 1;
set @a = (@a+1);
commit;
end while;
END
//
DELIMITER ;

我正在使用上述程序删除记录，但出现了类似语法的问题

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DELIMITER' at line 1

请帮我创建一个循环删除记录的程序。谢谢

特别感谢@Akina 的所有建议

请检查我删除记录的新程序。

drop procedure if exists PROC_WEEKLY_TASK_DELETE_LIMIT;
DELIMITER $$
CREATE DEFINER=root@localhost PROCEDURE PROC_WEEKLY_TASK_DELETE_LIMIT()
BEGIN

repeat delete from MY_TABLE where IS_VALID_DATE = 'false' limit 10000;
until not row_count()
end repeat; 
END$$
DELIMITER ;

Above procedure runs successfully on local but in case of server you need to remove the DEFINER only
