我试图从一个表中删除行，但不断得到一个语法错误，我不知道为什么。
我的问题是： DELETE * FROM questions WHERE catid = '680' 这是我的表格结构：

id (primary key, auto increment)
question
catid
ordering

通过上述查询，我得到以下错误：

There was an error running the query [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 '* FROM questions WHERE catid = "680"' at line 1]

表中有两行，一行catid=680和679。
