我想創建一個與ASP.NET連接到MySQL數據庫的GridView。數據如下所示。MySQL使用總結和案例
BusinessUnit OrderDate Canceled
UnitA 1/15/2013 N
UnitA 10/1/2013 N
UnitB 10/15/2013 N
UnitB 10/22/2013 N
UnitB 10/22/2013 N
基於以上的記錄,我想結果出現類似下面
BusinessUnit TodaysOrders ThisMonthsOrders ThisYearsOrders
UnitA 0 1 2
UnitB 2 3 3
我當前的代碼如下。它給我的錯誤(一些有關DatabaseName.sum不存在。檢查 功能名稱解析和解決方案」部分...)
Select
SUM (CASE WHEN (OrderDate)=DATE(NOW()) THEN 1 ELSE 0 END) AS TodaysOrders,
SUM (CASE WHEN YEAR(OrderDate) = YEAR(CURDATE()) AND MONTH(OrderDate) = MONTH(CURDATE()) THEN 1 ELSE 0 END) AS ThisMonthsOrders,
SUM (CASE WHEN YEAR(main_order_managers.creation_date) = YEAR(CURDATE()) THEN 1 ELSE 0 END) AS ThisYearsOrders
代碼繼續
FROM OrderTable WHERE OrderTable.Canceled. <> 'Y';
是sum情況下,最好使用這裏?
