在sql Query中的laravel unknown列

Question

'having clause'.column中的未知列'erp_purchase_order_details.received'出现在表格中，但它显示上述错误

代码：

$status_result = DB::table('erp_purchase_order_details')->select(DB::raw('COUNT(erp_purchase_order_details.product_category_id) as count_products'),DB::raw('COUNT(erp_purchase_order_details.received) as count_received'))
        ->havingRaw('erp_purchase_order_details.received > 1')
        ->where('erp_purchase_order_details.purchase_order_id','=',$purchase_order_id)
        ->get();

Answer 1

在HAVING子句条件中，您应该只使用聚合函数，而不是：

->havingRaw('erp_purchase_order_details.received > 1')

如果条件是关于列的，则将其移至WHERE子句，否则使用适当的聚合函数，如COUNT等。
