的錯誤信息是不是我想它應該是sqlfiddle，但如果我沒看錯的MySQL需要別名每個子查詢。所以，你可以把一個別名的子查詢，並嘗試再次執行？ – Bren

我已經嘗試過，它只顯示相同的錯誤...有什麼辦法可以做到這一點.. – jagan4040

我認爲'％Y-％m％-01'應該是'％Y-％m-01'，沒有％m％，[參考]（http://www.w3schools.com/sql/func_date_format.asp） –

的錯誤信息是不是我認爲它應該是。

什麼是你的mysql版本？ 2）另一個問題是，您在外部查詢中選擇了「product_line」，但在子查詢中選擇了product_line作爲「StringFact」，這就是爲什麼outer_query不會在外部查詢能夠選擇product_line。

我改變了你的查詢如下，它沒有問題執行。

這裏是您查詢http://www.sqlfiddle.com/#!2/26218/6
