DELIMITER $$
CREATE TRIGGER `applicationsUUID` BEFORE INSERT ON `applications`
FOR EACH ROW BEGIN
IF NEW.applicationID = '' THEN
SET NEW.applicationID = UUID();
END IF;
END
$$
DELIMITER ;

给出:- 您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，了解在 'DELIMITER $$

附近使用的正确语法

我知道这是 DELIMITER 语法的问题，但我看不出问题出在哪里。

尝试:

CREATE TABLE `applications` (
   `id` int(2) NOT NULL,
   -- `applicationID` varchar(36) character set utf8 collate utf8_unicode_ci NOT NULL,
   `applicationID` varchar(39) character set utf8 collate utf8_unicode_ci NOT NULL,
   `applicationType` enum('M','W') character set utf8 collate utf8_unicode_ci NOT NULL,
   `applicationName` varchar(30) character set utf8 collate utf8_unicode_ci NOT NULL,
   `applicationPath` varchar(100) character set utf8 collate utf8_unicode_ci NOT NULL,
   `isDeleted` tinyint(1) NOT NULL default '0',
   `lastModified` timestamp NOT NULL default CURRENT_TIMESTAMP
) ENGINE=MyISAM AUTO_INCREMENT=7 DEFAULT CHARSET=utf8;

INSERT INTO `applications` (`id`, `applicationID`, `applicationType`, `applicationName`,     `applicationPath`, `isDeleted`, `lastModified`)
VALUES
(1, 'a49af37e-7f4c-1032-a010-   c067c39cc60b', 'W', 'workshopWorkerWeb',   'http://www.workshopworker.com/workshopWorkerLogin/workshopWorkerLogin.html', 0, '2014-08-27   15:11:46'),

DELIMITER $$

CREATE TRIGGER `applicationsUUID` BEFORE INSERT ON `applications`
FOR EACH ROW
BEGIN
   IF NEW.applicationID = '' THEN
      SET NEW.applicationID = UUID();
   END IF;
END$$

DELIMITER ;
