带有 DELETE FROM 的 MySQL 语法？

Question

我有一段总是返回错误的 SQL，但我找不到它返回错误的原因。我已经连接到数据库没有错误。我正在运行 PHP 5.2.17、MySQL 5.5.25a 和 Apache 2.4.2。

SQL:

DELETE FROM mail WHERE to=1

错误:

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 'to=1' at line 1

Answer 1

TO 是 reserved word ，你需要使用反引号:

 DELETE FROM mail WHERE `to` = 1
