1.查詢之_string:

例子：

$m=M('indentlist');	
$where['_string'] = "(indentstate = 'NeedPay') or (indentstate = 'Shipped')";
$where['state'] =0;

SELECT * FROM `indentlist` WHERE ( (indentstate = 'NeedPay') or (indentstate = 'Shipped') ) AND ( `state` = 0 )

2.查詢之_complex,_logic:

例子：

$m=M('indentlist');
$email = $_GET['email'];
$condition['state'] =array('GT',0);
$condition['Indentstate'] ='Finished';
$condition['_logic'] ='or';
$map['_complex'] = $condition;//條件查詢，完成的訂單，退貨訂單，異常訂單
$map['email']  = $email;
$data=$m->where($map)->select();
 

SELECT * FROM `indentlist` WHERE ( (indentstate = 'Finished') or (state >0) ) AND ( `email` = '[email protected]' )
