Question

我在我的DataTable SQL语句中有这个查询，现在我很困惑，如何将日期参数传递给这个查询，日期只有2，startdate和enddate，但日期重复了几次。

SELECT        
                             (SELECT        COUNT(shift) AS Expr1

                               WHERE        (nip = dbo.JadwalDinas_DaftarKaryawan.NIP) AND (shift = 'B' OR
                                                         shift = 'E' OR

您可以声明变量以保存这些值：

DECLARE @sDate datetime, @eDate datetime

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

然后更换 CONVERT(DATETIME, '2015-12-01 00:00:00', 102) 同 @sDate 和 CONVERT(DATETIME, '2015-12-31 00:00:00', 102)与@eDate

。{

您可以创建一个包含所有此查询的存储过程，并将这些变量作为参数重新接收

CREATE PROCEDURE mySP  @sDate datetime, @eDate datetime
AS
--Your query here

C＃将重复参数传递给DataTable SQL语句
