根据SQL Server中的条件添加一行

Question

在SQL Server中，我有一个临时表，我想在每个员工下面添加一行。此处@STARTDATE是2015年8月1日，可以改变。

它应检查如下条件：

WHEN (JoiningDate of employee) > @STARTDATE THEN
   Case 
    When (EXPECTEDSTARTDATE(Its a project start date) = (JoiningDate of employee) Then NULL
    When (EXPECTEDSTARTDATE > (JoiningDate of employee) Then (Daysallocated)*8)-SUM(InstallCapacity))

  End
WHEN (JoiningDate of employee) = @STARTDATE THEN
  Case 
    When (EXPECTEDSTARTDATE = @STARTDATE) Then NULL
    When (EXPECTEDSTARTDATE > @STARTDATE) Then (Daysallocated)*8)-SUM(InstallCapacity))

  End

我的桌子是

我的结果为

我在下面添加了行

INSERT INTO #tempelevan 
SELECT EMPLOYEECODE, EMPLOYEENAME, 'Jayaraj Mariadhas Nadar' AS ReportingTo , 'Bench' AS PROJECTNAME, [Resource Pool] AS [Resource Pool], NULL AS ResourceStatus, ORGROLE AS ORGROLE,
[Resource DU] AS [Resource DU], [Resource DT] AS [Resource DT], NULL AS EXPECTEDSTARTDATE, NULL AS EXPECTEDENDDATE, NULL AS ResourcePercentage, NULL AS DaysAllocated, 
CASE 
 WHEN ((SELECT emp.joiningdate FROM tbl_pm_employee emp WHERE emp.employeecode=ft.EMPLOYEECODE) > @STARTDATE)
 THEN 
    CASE 
        WHEN (ft.EXPECTEDSTARTDATE = (SELECT emp.JoiningDate FROM tbl_pm_employee emp WHERE  emp.employeecode=ft.EMPLOYEECODE)) 
        THEN NULL 
        WHEN (ft.EXPECTEDSTARTDATE > (SELECT emp.JoiningDate FROM tbl_pm_employee emp WHERE  emp.employeecode=ft.EMPLOYEECODE)) 
        THEN ((SELECT dbo.countemployeebusinessdays(ft. employeecode, (SELECT emp.joiningdate FROM tbl_pm_employee emp WHERE emp.employeecode=ft.employeecode), @ENDDATE)*8)-sum(installcapacity)) 
    END
 WHEN ((SELECT emp.joiningdate FROM tbl_pm_employee emp WHERE emp.employeecode=ft.employeecode) = @STARTDATE)
 THEN 
    CASE 
        WHEN (ft.expectedstartdate = @STARTDATE) 
        THEN NULL 
        WHEN (ft.expectedstartdate > @STARTDATE) 
        THEN ((SELECT dbo.countemployeebusinessdays(ft. employeecode, @STARTDATE, @ENDDATE))*8)-sum(installcapacity)
    END
END installcapacity, 
(1 - SUM([ActualAllocationPercentage])) as ActualPercentage
FROM #tempelevan ft GROUP BY ft.EMPLOYEECODE, ft.EMPLOYEENAME, ft.[Resource Pool], ft.ORGROLE, ft.[Resource DU], ft.[Resource DT], ft.EXPECTEDSTARTDATE

在结果表中，对于特定员工，应该只有一行Bench，但我遇到多行问题。如果有多个项目分配给同一员工，则显示行。

此外，我想隐藏Install capacity为Null的行。

这不是答案。在这里添加，不能留在评论中。
