SSRS报告参数需要多个值

Question

我正在制作SSRS报告，其参数为“Quarter1”，“Quarter2”，“Quarter3”和“Quarter4”，我有一个需要获取用户值并获取数据的查询对于该季度，如果选择第1季，我的查询将如此。我正在使用VS 2010 BIDS for SSRS和SQL 2012 for database

Select 
CASE WHEN MONTH(DateGenerated) <= 3 THEN '1Q/'  
WHEN MONTH(DateGenerated) > 3 and MONTH(DateGenerated) <= 6 THEN '2Q/'
WHEN MONTH(DateGenerated) > 6 and MONTH(DateGenerated) <= 9 THEN '3Q/'
WHEN MONTH(DateGenerated) > 9 and MONTH(DateGenerated) <= 12 THEN '4Q/' END 
as GenDate, Notes, Equation

from SubTask 

 where Year(DateGenerated) = @year and MONTH(DateGenerated) in (@Quarter) 

在SSRS中执行此操作时，我无法将第（1，第2和第3）个值作为Quarter1的值。有没有办法让我失踪。感谢帮助..

来自SSRS的参数将以逗号分隔的字符串形式出现，因此我们需要一个函数来分割值。

例如，如果您的参数是Quarter ...那么您的SQL看起来像

Create Procedure xyz
@Quarter varchar(50) = null
as BEGIN

Select 
CASE WHEN MONTH(DateGenerated) <= 3 THEN '1Q/'  
WHEN MONTH(DateGenerated) > 3 and MONTH(DateGenerated) <= 6 THEN '2Q/'
WHEN MONTH(DateGenerated) > 6 and MONTH(DateGenerated) <= 9 THEN '3Q/'
WHEN MONTH(DateGenerated) > 9 and MONTH(DateGenerated) <= 12 THEN '4Q/' END 
as GenDate, Notes, Equation

from SubTask 

where Year(DateGenerated) = @year and MONTH(DateGenerated)
 in (Select Value From dbo.FNSplit(@Quarter,','))

功能是......

CREATE FUNCTION [dbo].[FnSplit]
(
@List nvarchar(max),
@SplitOn nvarchar(5)
)  
RETURNS @RtnValue table 
(

Id int identity(1,1),
Value varchar(max)
) 
AS  
BEGIN
While (Charindex(@SplitOn,@List)>0)
Begin 
Insert Into @RtnValue (value)
Select
Value = ltrim(rtrim(Substring(@List,1,Charindex(@SplitOn,@List)-1))) 
Set @List = Substring(@List,Charindex(@SplitOn,@List)+len(@SplitOn),len(@List))
End 

Insert Into @RtnValue (Value)
Select Value = ltrim(rtrim(@List))
Return
END
