帮助在codeigniter中写入查询的哪个部分

Question

我使用codeigniter活动记录类编写了一个查询。

编写查询时，它看起来像

WHERE `account` = 1 
AND cgl.contactId IS NULL 
AND `firstName` LIKE 'M%' 
OR `lastName` LIKE 'M%'

但我需要它看起来像

WHERE `account` = 1 
AND cgl.contactId IS NULL 
AND (`firstName` LIKE 'M%' 
OR `lastName` LIKE 'M%') //notice the brackets

我该怎么做？

Answer 1

$this->where(array('account' => 1, 'cgl.contactId' => NULL);
$this->where(("firstName` LIKE 'M%' OR `lastName` LIKE 'M%'"))
