任何人都可以告訴我什麼是我的創建觸發器語法錯誤？

Question

我第一次嘗試觸發器。

當我嘗試使用下面創建觸發器：

CREATE TRIGGER t_foldersPrivate BEFORE DELETE ON foldersPrivate 
FOR EACH ROW BEGIN 
DELETE FROM programs WHERE folderType = '0' AND folderID = OLD.ID; 
END; 

我收到以下錯誤：

`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` 

（MySQL的5.1.37）

如果我擺脫FO創建觸發器語句的delete語句正常工作。所以我認爲它必須與此有關。但對於我的生活，我不知道什麼...

你應該改變分隔符。

事情是這樣的：

DELIMITER $$ 

CREATE TRIGGER t_foldersPrivate BEFORE DELETE ON foldersPrivate 
FOR EACH ROW BEGIN 
DELETE FROM programs WHERE folderType = '0' AND folderID = OLD.ID; 
END$$ 

DELIMITER ; 

此外，您應該單獨檢查刪除查詢。它工作嗎？
