mysql - Yii + MySQL 错误 1064

Question

我每次都会遇到语法错误:

$skills = SubSkills::model()->findAll(array('order'=>'number DESC','condition'=>'number > 0 AND user_id=:user_id AND select = 0', 'params'=>array(":user_id" =>1),'offset'=>0,'limit'=>2,
));

如果我去掉“select = 0”部分就可以了。

错误如下:

CDbCommand failed to execute the SQL statement: SQLSTATE[42000]: Syntax error or access violation: 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 'select < 1 ORDER BY number DESC' at line 1

我认为发生这种情况是因为“SELECT”作为行名会与 MySQL 冲突。有办法避免这种情况吗？

谢谢!

Answer 1

Select 由 SQL 使用。如果您正在运行查询，请始终对列名称使用反引号:

$skills = SubSkills::model()->findAll(array('order'=>'number DESC','condition'=>'number > 0 AND `user_id` = :user_id AND `select` = 0', 'params'=>array(":user_id" =>1),'offset'=>0,'limit'=>2,
));

您使用双引号的解决方案也是解决此类冲突的有效解决方案。但我相信使用反斜线更常用，因为它提高了可读性。
