如何绕过 SQL Server 存储过程中的日期参数以取回所有数据

Question

我目前正在使用getShifts存储过程来获取前端 2 个独立功能的数据。 我的存储过程需要一个参数Selected Date ，它在传递日期时返回特定日期的记录。

我正在尝试为我的一项功能绕过ShiftDate参数，并将其用作获取全部功能。 有没有办法将假日期传递给存储过程以接收所有记录？

BEGIN
    SELECT 
        n.ID, n.ID, m.SearchFullNameFL as ProfileName, n.SchedID, 
        s.LicenseID, f.ID as UnitID, f.UnitName, 
        n.Hours, s.ShiftDate, s.SchedShiftID, ss.Description as SchedShift,  
        ss.Hours as SchedShiftHours, t.ID as TransactionTypeId,
        (SELECT COUNT(b.ID) 
         FROM Sched b
         INNER JOIN Ref_SchedShift ss ON ss.ID = b.SchedShiftID AND ss.DSN > 0
         WHERE b.ExpiredBy = 0 AND b.ShiftDate = @ShiftDate -->= @StartDate 
           AND b.EndDate <= @EndDate
           AND b.FacUnitID IN (SELECT Id FROM FacUnit 
                               WHERE FacilityID = @FacilityID) 
           AND b.ID = s.ID) AS ShiftsWorked,
        n.OverTimeReasonTypeID, n.Comment, n.Ref_NoLunchID as NoLunchID, 
        nl.NoLunchType
    FROM
        NewClockIns n
    INNER JOIN 
        Members m ON m.ID = n.ID
    INNER JOIN 
        Sched s ON s.ID = n.SchedID AND s.ExpiredBy = 0
    INNER JOIN 
        Ref_Method rm ON n.Ref_MethodID = rm.ID
    INNER JOIN 
        Ref_ClockTransactionType t ON t.ID = n.Ref_ClockTransID
    INNER JOIN 
        FacUnit f ON f.ID = n.FacUnitID
    INNER JOIN 
        Ref_License l ON l.ID = s.LicenseID
    INNER JOIN 
        Ref_SchedShift ss ON ss.Id = s.SchedShiftID
    LEFT JOIN 
        Ref_NoLunch nl ON nl.ID = n.Ref_NoLunchID
    WHERE  
        s.ShiftDate = @ShiftDate-->= @StartDate 
        AND s.EndDate <= @EndDate 
        AND s.ClockInsAgencyApprovedByID > 0 
        AND ((@IsApproved = 1 AND s.ClockInsFacilityApprovedByID > 0) 
             OR 
             (@IsApproved = 0 AND s.ClockInsFacilityApprovedByID = 0)) 
        AND f.Id IN (SELECT ID FROM @UnitIDList) 
        AND n.ExpiredBy = 0
END

Answer 1

你在找or ？

(s.ShiftDate = @ShiftDate or @ShiftDate is null)

然后可以传入NULL并忽略过滤器。

Answer 2

尝试这个：-

ShiftDate =(Case When @IsApproved = 1 Then @ShiftDate Else null End)
