如何在ssrs 2005报表中的非查询可用值中为多个值分配一个相同的标签？

Question

Parameters - Multiple Values For One Label - Possible?

Sorry my modified Question.....

I have question to ask,... Is it possible to have multiple values for ONE label in non-queried available values in SSRS 2005? i want to join fields value in a single row like,

Works: (But this bring a long list in drop down menu - which i donot want)

Label                Value
---------------------------
Site-1                 150
Site-1                 151 
Site-2                 152
Site-2                 153


Required result (Which i want - in one line)

Label                Value
---------------------------
Site-1                 150,151
Site-2                 152,153
(which will bring one label and related multi-value in drop down or combo box.
But the problem is that ColumnName IN (@Site) does not work with multi-value.)

More description of the problem:

Let say, I have a field/column

 Name = Site
 Value = C150,C151, C152, C153

I want drop down menu on report with

 C150,C151(as Site-1) & C152,C153(as Site-2)

So I created parameter ie @getSite and set values as multi-value in the report as

 Label                       Value
 ---------------------------------------------
 Site-1                      (150,151)
 Site-2                      (152,153)

And set my parameter as @getSite:= Parameters!@getSite.Value And Query i wrote as,

SELECT  * FROM ..
WHERE Site IN (@getDisease)

But after all these, my report result is empty,literally no result. It seems like if i select only one value as Site-1 = 150, then it works but not two or more values in one line, why it is not possible?? if yes then how?

Please help!!!

Answer 1

Yes just Right Click on your parameter in your Report Data window under Parameters folder and select the check box for allow multiple values as follows

this is what I said before you need to put your column name inside a set of paranthesis something like this

SELECT  * FROM ..
       WHERE (Site IN (@getDisease))

Answer 2

I have been working on this problem for a while and I think I have finally figured it out...

Basically you need to use a backwards case statement in your SELECT statement, put that in a derived query and then reference it in the outer WHERE clause..

SQL:

SELECT * FROM 
(
SELECT
Label
, value
, CASE WHEN [value] IN (150,151) THEN 'site-1' WHEN [value] IN (152,153) THEN 'site-2' END AS [grouped_values]
)
WHERE grouped_values IN (@getSite);

*Note: This answer only works on values that are mutually exclusive, if both sets had the same value included then it would be problematic..

-- Hopefully this can put you in the right direction. I am finding a lot of the reporting services tricks require reverse engineering or at least some reverse thinking.
