mysql - mysql变量声明的语法错误

Question

CREATE PROCEDURE dorepeat(IN p1 INT)
BEGIN
  DECLARE x INT DEFAULT 0;
  REPEAT SET x = x + 1; UNTIL x > p1 END REPEAT;
END

我收到一个语法错误:

#1064 - 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 '' at line 3

但对我来说，一切似乎都是正确的。我真的没有任何线索!有人可以帮忙吗？

谢谢

您需要暂时change the delimiter因此，当 MySQL 客户端在第 3 行看到分号时，它不会认为您的语句已完成:

DELIMITER //

CREATE PROCEDURE dorepeat(IN p1 INT)
BEGIN
  DECLARE x INT DEFAULT 0;
  REPEAT SET x = x + 1; UNTIL x > p1 END REPEAT;
END//

DELIMITER ;
