我刪除了「mysqli」標籤並將其替換爲SQL Server，因爲語法顯然是SQL Server。另外，你應該嘗試簡化你的查詢。正如所寫，很難遵循並確定錯誤的可能性。 –

您正在嘗試在SUM內部使用LEAD - 這就是爲什麼您會收到錯誤。而不是LEAD使用OUTER APPLY獲得您需要的下一個值。

Select STD.StoreNo As StoreNo, 
     CheckDate As CheckDate, 
     ProductBarCode as ProductBarCode, 
     SUM(case 
       when s.StockTakingQty is null and [CheckDate] <> EOMONTH([CheckDate]) 
       then STD.[StockTakingQty] 
       else STD.[StockTakingQty] - s.StockTakingQty 
      end) AS ProducQty 
Into ##temp 
From StockTakingDetail STD 
Inner Join (
    Select StoreNo, 
      CheckNo, 
      CheckDate 
    From StockTakingMain SM 
    )StocktakingMain 
    On STD.CheckNo =StockTakingMain.CheckNo 
OUTER APPLY (
    SELECT TOP 1 * 
    FROM StockTakingDetail 
    WHERE SomeIDfield = STD.SomeIDfield 
    ORDER BY StockTakingQty 
    ) s 
Where CheckDate Between @date1 AND @date2
