錯誤雖然通過長查詢

Question

我有一個查詢。

DECLARE @fromDate AS DATETIME = '01/28/2009'; 
DECLARE @ToDate AS DATETIME = '01/28/2011'; 
DECLARE @IsMonthWise AS BIT = 1 
DECLARE @temp AS TABLE( userId BIGINT 
         , Visits INT 
         , DownLoads INT) 
DECLARE @tempmonth AS TABLE( userId BIGINT 
           , Visits INT 
           , DownLoads INT 
           , MonthYear NVARCHAR(50)) 

IF @IsMonthWise = 0

    WHERE region.definition_id = 43 
    ORDER BY User_Name ASC 
      , MonthYear DESC 
END 

DELETE FROM @temp 

DELETE FROM @tempmonth 

IT如果在SQL服務器中運行，可以正常工作。但是，如果我通過相同的字符串從C＃代碼（ExecuteReader）。它不執行。

如果我從後面的代碼中複製查詢並粘貼到SQL Server中，它將進入單行。我認爲這是我的查詢未執行的原因。

請讓我知道怎樣的方式來傳遞從我的應用程序執行長查詢（C＃）

感謝

首先嚐試聲明的變量：

DECLARE @fromDate AS DATETIME; 
DECLARE @ToDate AS DATETIME; 

等等

然後設置它們

SET @fromDate = '01/28/2009'; 
SET @ToDate = '01/28/2011'; 

不確定這是否會解決您的問題，或者不會看到設置您的SqlCommand對象並執行此查詢的代碼難以分辨，但這是將值分配給變量的首選方法。
