当我在TSQL中执行以下操作时,NULL即使有值,我也会得到.

这是我的代码:

CASE
    WHEN cal.Weekday = ' ' OR HOLIDAY.DateInfo > ' '
        THEN WEPHWORK.WEPHWORK + OCESAWD.OCESAWD + OCESAWE.OCESAWE 
    ELSE OCESAWD.OCESAWD + OCESAWE.OCESAWE
END as weighted

为什么会这样？

ALTER PROCEDURE [dbo].[REPORTING_MonthlyClientTimesheet_wrapper2_TRR_Month]
      (@StartDate DATETIME,
       @taskcode VARCHAR(250),
       @username VARCHAR(250))
AS 
BEGIN 
      SET NOCOUNT ON 
      DECLARE @ProcedureName SYSNAME     

        -- Give them one full month of records
      DECLARE @EndDate DATETIME


      SET @ProcedureName = OBJECT_NAME(@@PROCID) 

       --SET @EndDate = DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,@StartDate)+1,0)) -- end month
      SET @EndDate = DATEADD(s, -1, DATEADD(YY, DATEDIFF(YYYY, 0, @StartDate) + 1, 0)) --set to end of Year


      BEGIN TRY


            SELECT DISTINCT
                @username,
                cal.calendaryear,
                cal.calendarmonth,
                cal.calendarday,
                DATEPART(wk, Calendardate) AS weekno,
                DATENAME(month, DATEADD(month, cal.calendarmonth - 1, 0)) AS iMonthName,
                DATEADD(s, -1, DATEADD(YY, …
