我想連接用繩子新的用戶名和我有以下觸發:MySQL的觸發器 - 截斷不正確雙重錯誤
CREATE DEFINER=`root`@`localhost` TRIGGER `rating_platform`.`admins_BEFORE_INSERT` BEFORE INSERT ON `admins` FOR EACH ROW
BEGIN
SET NEW.username = NEW.username + "test";
END
我收到此錯誤:
ERROR 1292: 1292: Truncated incorrect DOUBLE value: 'test'
我是什麼做錯了?
謝謝,按預期工作! –
