SQL Server Reporting Services - Multi-Value Params - part 2

OK, so in my last post I talked about how SQL server reporting services does not handle multi-value parameters and I would need to work around it. So I thought I'd share my work around for those that might need to do the same.

Basically I ended up writing a User Defined Function and compiling it on the SQL server I was pulling the reporting data from. This function will parse a string using the supplied delimiter and then return a table with an index and a bigint. I needed to return a recordset of bigints for a comparison but you may need another data type.


CREATE  FUNCTION StringToBigIntTable (
    @TargetString varchar(8000),
    @SearchChar varchar(1)
        idPos smallint not null identity,
        ExtractedInt bigint null

    SET @TargetString = COALESCE(@TargetString,'')
    DECLARE @SearchCharPos smallint,
            @LastSearchCharPos smallint
    SET @SearchCharPos = 0
    WHILE 1=1
        SET @LastSearchCharPos = @SearchCharPos
        SET @SearchCharPos = CHARINDEX( @SearchChar, @TargetString, @SearchCharPos + 1 )
        IF @SearchCharPos = 0
            INSERT @Set( ExtractedInt ) VALUES ( Convert(bigint, SUBSTRING( @TargetString, @LastSearchCharPos + 1, DATALENGTH( @TargetString ) )) )
            INSERT @Set( ExtractedInt ) VALUES ( Convert(bigint, SUBSTRING( @TargetString, @LastSearchCharPos + 1, @SearchCharPos - @LastSearchCharPos - 1 )) )



Then in my data view for my report (the RDL file) I use the following sql statement , calling my function to parse the parameter and return a recordset of bigints:


FROM vwExpectedReport
WHERE ProgramID IN (select ExtractedInt from dbo.StringToBigIntTable(@ProgramIDs, ','))

I hope this helps someone down the road.

Hey Ian

Thanks so much for your help.  

This worked just great for my code.

Keep the good work

Thanks Ian.  The implementation of these multi-value parameters is abominable.  You've been helpful in confirming that yet again code is going to have to written around a "half feature".

Nice simple solution.

...and I was about to implement an XML parameter.  Jeeze!  :)

Ever tried this?

=split(join(Parameters!YourMultiValueParamter.Value, ","), ",")

Silly I know...

I agree - this feature should have been included COMPLETELY or removed COMPLETELY.  

It is just another example of how code is required to make RS work properly.

(my own sarcasm:  Do you think MS developers ever used Crystal Reports?)

works for me, thanks for posting the code.

Hey this code was helpful, thanks.

But this seems to be working for me only if I have the exact code of the RDL in a Stored Procedure. If I add the exact code to the RDL it says too many arguments for the function dbo.StringToBigIntTable..... Do you have any clue as in why it says so? It just doesn't make any sense to me as to why the same code that works on the SP doesn't work on the RDL....

I thought this was it


FROM vwExpectedReport

WHERE ProgramID IN (@ProgramID'))

I get an error:

function "StringToBigIntTable" has too many arguments specified

When i select only 1 value it works OK, but i need multi value

I use you UDF and query is:

SELECT proj_id, proj_short_name FROM Project

WHERE proj_id IN


select ExtractedInt from dbo.StringToBigIntTable(@ProjectIds, ',')

FROM vwExpectedReport

Worked for me too
