在cakephp/sql server中获取更新记录的PK - Getting PK of updated records in cakephp/sql server

Getting PK of updated records in cakephp/sql server

我使用批量更新在两个表之间同步数据，如下所示

$sqlProc="
UPDATE cards
SET cards.card_no = t2.card_number,
    cards.expiry_date=t2.expiry_date OUTPUT INSERTED.Id AS 'updated_id'
FROM cards
INNER JOIN card_temp t2 ON (cards.account_no = t2.account_number
                            AND cards.customer_name=t2.customer_name)
WHERE cards.is_disabled='N'";
        debug($this->Request->query($sqlProc));

上面的查询也会在sql server编辑器中使用OUTPUT INSERTED.Id AS 'updated_id'返回更新记录的主键，但是当我调试sql

时

debug($this->Request->query($sqlProc));

则查询成功返回true，查询不成功返回false。

是否有任何想法来获取updated_id数组，以便我可以使用这些id到另一个表

我终于明白了。我创建了一个中间表，执行如下操作

//inserted into temp_id (bridge table)
$sqlProc="insert into temp_id select * FROM (update cards 
                        set         cards.card_no = t2.card_number,cards.expiry_date=t2.expiry_date
                        OUTPUT INSERTED.Id AS 'updated_id'
                        from        cards 
                        inner join  card_temp t2
                        on          (cards.account_no = t2.account_number and cards.customer_name=t2.customer_name)
                        where cards.is_disabled='N'
                        ) AS t";
        $this->Request->query($sqlProc);
        //fetch from intermediate table
        $sqlSel="SELECT * FROM temp_id";
        $arr=$this->Request->query($sqlSel);
          //this array will fetch all updated id's
        debug($arr);
        $sqlDel="DELETE FROM temp_id";
        $this->Request->query($sqlDel);
