用mysql选择使用inet_ntoa的SQL语法错误

Question

我有一个ip存储在数据库中作为unsigned int但是当我尝试运行这个select我得到一个语法错误。我试过以下两个版本。

SELECT `id`, INET_NTOA(`from`) AS from, INET_NTOA(`to`) AS to, `campaignid`  FROM `customiplist` WHERE `campaignid` = 1

SELECT id, INET_NTOA(from) AS from, INET_NTOA(to) AS to, campaignid  FROM customiplist WHERE campaignid = 1

#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 'from, INET_NTOA(`to`) AS to, `campaignid` FROM `customiplist` WHERE `campa' at line 1

我觉得我疯了，因为所有的列名和表名都是正确的。

Answer 1

FROM和TO是reserved keywords in MySQ L。如果您要使用它们，则必须将它们包装在刻度线中：

SELECT `id`, INET_NTOA(`from`) AS `from`, INET_NTOA(`to`) AS `to`, `campaignid`  FROM `customipblocklist` WHERE `campaignid` = 1

老实说，这些都是列名的错误选择。如果可能，我建议更换它们。
