Question

在这种情况下 - 表'区'有两列 - id，district。表'派对'有列 - parties_partyname，parties_district

parties.parties_partyname = districts.district

另一个表'bill'有列partyname，billamount。

bills.partyname = parties.parties_partyname

现在我想要的是看下面的每个区的billamount -

District    Sale
A   10000
B   20000
C   10000
D   20000

我的搜索查询是 -

$query = Districts::find();
        $subquery = Bills::find()->select('parties_district,bills_partyname, billdate, sum(billamount) as sale')->groupBy(['parties_district']);
        $subquery->joinWith(['parties']);
        $query->leftJoin(['T' => $subquery], 'T.parties_district = districts.district');

我在销售栏中收到“（未设置）”。请告诉我需要做哪些更改。另外，我试图在partySearch模型中打破这样的部分 -

$query = Parties::find();
        $subquery = Bills::find()->select('bills_partyname, billdate, sum(billamount) as sale')->groupBy(['bills_partyname']);
        $query->leftJoin(['T' => $subquery], 'T.bills_partyname = parties_partyname');

我仍然没有设置为销售栏
