在where子句中使用DATE_ADD更新MySQLi类

Question

I am running this query in phpmyadmin and mysqli() and it update records properly. But on running it in joshcam's MySQLi Database class it updates wrong data.

Query:

UPDATE table SET `status` = 0 WHERE   time <= DATE_ADD( NOW(), INTERVAL -2 MINUTE ) 

PHP Code:

$db->where('time', 'DATE_ADD( NOW(), INTERVAL -2 MINUTE )', '<=');
$db->update( 'table', array('status'=> '0') );

Also Tried:

$db->where('time', $db->now('-2m'), '<=');
$db->update( 'table', array('status'=> '0') );

Is there anything wrong in MySQLi class query

Answer 1

尝试这个：

UPDATE table SET status = 0 WHERE time <= DATE_SUB( NOW(), INTERVAL 2 MINUTE )
