Question

这是我第一次学习存储过程。我在这里：

DELIMETER //
DROP PROCEDURE IF EXISTS RepeatTomProc //
CREATE PROCEDURE RepeatTomProc()
BEGIN
    DECLARE x  INTEGER;
    SET x = 1;
    REPEAT
            INSERT INTO TOM VALUES(x);
            SET  x = x + 1;
    UNTIL x  > 100
    END REPEAT;    
END //
DELIMITER;

我想要发生的是，当循环尚未完成时，它会将x值插入表TOM。

目前表TOM为空。

表格

：

CREATE TABLE TOM (
    TOM_ID int(10) unsigned NOT NULL AUTO_INCREMENT,
    PRIMARY KEY (TOM_ID)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

我的问题是当我尝试通过复制和粘贴我的mysql终端中的代码来创建存储过程时出现以下错误：

mysql> DELIMETER $$
-> DROP PROCEDURE IF EXISTS RepeatTomProc $$
-> CREATE PROCEDURE RepeatTomProc()
-> BEGIN
-> DECLARE x INT;

 // It displays lots of other possibilities which I have ommitted

END REPEAT' at line 1
mysql> END $$
-> DELIMITER;

我的代码来自：Loop in Stored Procedures

您错误输入了DELIMITER

试试这个

DELIMITER //
DROP PROCEDURE IF EXISTS RepeatTomProc //
CREATE PROCEDURE RepeatTomProc()
BEGIN
    DECLARE x  INTEGER;
    SET x = 1;
    REPEAT
            INSERT INTO TOM VALUES(x);
            SET  x = x + 1;
    UNTIL x  > 100
    END REPEAT;    
END //
DELIMITER ;

此外，您最后需要DELIMITER和;之间的空格

mysql：我的存储过程出了什么问题？
