thinkphp 多表连接子查询 group by 分组以最新的一条数据为组

用这个

        $subQuery = Db::name('wms_orderitems')->distinct(true)->field('kw_id,orders_id,product_id')->order('items_id desc')->buildSql();$list = Db::name('wms_orders')->alias('order')->join($subQuery.' item','item.orders_id=order.orders_id')->field('order.dd_date,item.kw_id,item.product_id')->group('item.kw_id')->order('item.kw_id')
//                ->fetchSql(true)->select()->toArray();

在这里插入图片描述

下面的可以参考

$subQuery = Db::name('purchase_order_line')->distinct(true)->order('purchase_order_line_id desc')->buildSql();$re = Db::name('purchase_order')->alias('a')->field(['a.company_id','a.purchase_order_id','b.price','b.unit_cost','b.product_id','b.purchase_order_line_id','ifnull(sum(ff.purchase_quantity),0) as ruku_sum','ifnull(sum(f.purchase_quantity),0) as tuihuo_sum'])->join($subQuery.' b','a.purchase_order_id=b.purchase_order_id')->whereTime('a.create_date','>',strtotime('-15 day'))
//            ->where(['a.status'=>4,'a.order_type_id'=>1])->where('a.order_type_id', 1)->where(function ($query) {$query->where('a.status', 4);
//                    ->whereOr('a.is_wms', 1);})->leftjoin('cd_purchase_order_line_ruku ff','ff.purchase_order_id >= b.purchase_order_id and ff.price=b.price and b.product_id=ff.product_id and ff.status=4 and ff.order_type_id=1 and ff.company_id=a.company_id')->leftjoin('cd_purchase_order_line_tuihuo f','f.product_id=b.product_id and f.purchase_order_id > a.purchase_order_id  and b.price=f.price  and f.status=7 and f.order_type_id=2 and f.company_id=a.company_id')->having('ruku_sum > tuihuo_sum')->group('b.product_id,a.company_id')->select();
