希望你能有所幫助。SQL查詢提供行數銷售訂單
我們有一個顯示網格的應用程序。我們可以使用我正在掙扎的子查詢將自定義字段添加到網格中。主網格查詢看起來像這樣。

子查詢基本上提供一個查看銷售訂單並返回該訂單內行數的列。當我這樣做，我得到如下：
有檢索數據的問題： 子查詢返回的多個值。當子查詢遵循=，！=，<等 或子查詢用作表達式時，這是不允許的
下面是查詢與子查詢完成。如果有人能夠幫助這將是驚人的

在你的子查詢，你可以通過寫組，所以有可能你會得到多行。把子查詢不會有工作 – User
好了，我該如何糾正呢？我不確定這樣你的幫助將非常感激 – TowelsRus
整頓，第一隻執行子查詢，看看它是否是導致多行，如果根據您需要的結果的子查詢，以便更改組的條件。 – Nitin
