I wouldn't ask if i wasn't sure that i have 100% no idea why this isn't working, so, in PHP i'm simply trying to update a value in the MySQL database:
The field im updating - Name: read - Type: tinyint - Length: 1
Here is the PHP code:
do_SQL("UPDATE messages SET read=1 WHERE id='".$id."'");
The do_SQL function is working for everything else, so it's something wrong with this statement. I have tried putting 1 in '1' and it still didn't work.m The error is:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'read=1 WHERE id='1'' at line 1
Thanks for reading!
read
是MySQL中的一个关键字,因此您必须在不加引号的情况下使用它(带反引号):
do_SQL("UPDATE messages SET `read`=1 WHERE id='".$id."'");
read is probably a reserved word in MySQL.
Yep it is MySQL Reserved Words
Next time check that list before creating a column with a name that's likely to be used already by the database system.
如果id
是数字,请尝试删除引号:
do_SQL("UPDATE messages SET `read` = 1 WHERE id = ".$id);
Don't quote $id. Let PHP do substitution in the string.
do_SQL("UPDATE messages SET read=1 WHERE id=$id.");
没有转义字符。
do_SQL('UPDATE messages SET read=1 WHERE id=\''.$id.'\'');
