C＃將重複的參數傳遞給DataTable SQL語句

Question

我在我的DataTable SQL語句中有這個查詢，現在我混淆了，如何將日期參數傳遞給此查詢，日期只有2，startdate和enddate，但日期重複了幾次倍。

SELECT   
          (SELECT  COUNT(shift) AS Expr1 
           FROM   dbo.JadwalKerja 
           WHERE  (nip = dbo.JadwalDinas_DaftarKaryawan.NIP) AND (shift = 'B' OR 
                 shift = 'E' OR 
                 shift = 'F' OR 
                 shift = 'G' OR 
                 shift = 'H' OR 
                 shift = 'J' OR 
                 shift = 'P') AND (date >= CONVERT(DATETIME, '2015-12-01 00:00:00', 102)) AND (date <= CONVERT(DATETIME, '2015-12-31 00:00:00', 102))) AS P,

你可以聲明變量來持有這些值，因爲這：

DECLARE @sDate datetime, @eDate datetime 

SET @sDate = '2015-12-01 00:00:00' 
SET @eDate = '2015-12-31 00:00:00' 

然後用@eDate

更換 CONVERT(DATETIME, '2015-12-01 00:00:00', 102) 與 @sDate 和 CONVERT(DATETIME, '2015-12-31 00:00:00', 102)您還可以創建存儲過程包含所有這些查詢並接收這些變量a s參數

CREATE PROCEDURE mySP @sDate datetime, @eDate datetime 
AS
