我尝试使用多个连接查询，但很少有字段返回空。我使用了以下查询。当我在MySql中使用类似的查询时，我得到了我需要的结果，但这在cakephp查询中不起作用。
$selQry2= $this->CustomerProfile->find('all',array(
'fields'=>array('CustomerProfile.firstname as cust_firstname,CustomerProfile.lastname as cust_lastname,
CustomerAddress.address1 as cust_address1,CustomerAddress.address2 as cust_address2,CustomerAddress.phone1 as cust_phone,
CustomerAddress.email as cust_email,CustomerAddress.city as cust_city,CustomerAddress.state as cust_state,
CustomerAddress.zipcode as cust_zipcode,AddedbyCustomer.'. configure::read('log_usr_fld').',
UsersProfileBackend.firstname as sal_firstname,UsersProfileBackend.lastname as sal_lastname,
UsersProfileBackend.phone as sal_phone,UsersProfileBackend.email as sal_email'),
'conditions'=>array('CustomerProfile.customerid'=>$customer_id),
'joins' =>array(array (
'table'=>'customer_address',
'alias'=> 'CustomerAddress',
'type' => 'left',
'conditions' => array('CustomerProfile.customerid = CustomerAddress.customerid')
),
array(
'table'=>'addedby_customer',
'alias'=> 'AddedbyCustomer',
'type' => 'left',
'conditions' => array('CustomerProfile.customerid = AddedbyCustomer.customerid')
),
array(
'table'=>'users_profile_backend',
'alias'=> 'UsersProfileBackend',
'type' => 'left',
'conditions' => array('AddedbyCustomer.'. configure::read('log_usr_fld') => 'UsersProfileBackend.user_id' )
),
),
'limit' => 1
));
我获得上述查询的结果是：
Array
(
[0] => Array
(
[cust_firstname] => betty
[cust_lastname] => haycraft
[cust_address1] =>
[cust_address2] =>
[cust_phone] => 2702302676
[cust_email] => testsasdf@test.com
[cust_city] =>
[cust_state] =>
[cust_zipcode] =>
[allocatedtoprimaryid] => 239
[sal_firstname] =>
[sal_lastname] =>
[sal_phone] =>
[sal_email] =>
)
)
查询的预期结果是：
Array
(
[0] => Array
(
[cust_firstname] => betty
[cust_lastname] => haycraft
[cust_address1] =>
[cust_address2] =>
[cust_phone] => 2702302676
[cust_email] => testsasdf@test.com
[cust_city] =>
[cust_state] =>
[cust_zipcode] =>
[sal_firstname] => Cl
[sal_lastname] => Wilson
[sal_phone] => 270-737-0005
[sal_email] => c.l.wilson@kiastoreetown.com
)
)
Sql查询是：
SELECT a.firstname as cust_firstname,a.lastname as cust_lastname,b.address1 as cust_address1,
b.address2 as cust_address2,b.phone1 as cust_phone,b.email as cust_email,b.city as cust_city,
b.state as cust_state,b.zipcode as cust_zipcode,d.firstname as sal_firstname,d.lastname as sal_lastname,
d.phone as sal_phone,d.email as sal_email
FROM customer_profile as a left join customer_address as b
on a.customerid=b.customerid
left join addedby_customer as c
on a.customerid=c.customerid
left join users_profile_backend as d
on c." . configure::read('log_usr_fld') . "=d.user_id WHERE a.customerid='$customer_id' LIMIT 1
