用mysql选择使用inet_ntoa的SQL语法错误

Question

I have an ip stored in the database as an unsigned int but when i try and run this select i get a syntax error. i have tried both versions below.

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

i feel like i'm going mad because all the column names and table name is correct.

Answer 1

FROM and TO are reserved keywords in MySQL. If you're going to use them, you must wrap them in ticks:

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

Honestly, those are bad choices for column names. I recommend changing them if at all possible.
