Question

I am working on a simple report in Visual Studio 2010 where originally I have a direct query:

SELECT     
   DOCDATE, DOCID, CUSTNMBR, CUSTNAME, DOCAMNT
FROM         
   SOP30200
WHERE     
   (DOCDATE BETWEEN @Fromdate AND @Todate)
GROUP BY 
   DOCDATE, DOCID, CUSTNMBR, CUSTNAME, DOCAMNT
HAVING 
   (CUSTNAME = @Custname OR @Custname IS NULL) AND (DOCID IN (@DocID))

with the DOCID parameter set to “Allow multiple values” which works great.

However, when I create a stored procedure:

CREATE Procedure [dbo].[Jae_EraSales]  
   @Custname nVARCHAR(MAX),
   @DocID nVARCHAR(50),
   @Fromdate datetime,
   @Todate datetime
as
   SELECT     
      DOCDATE, DOCID, CUSTNMBR, CUSTNAME, DOCAMNT
   FROM         
      SOP30200
   WHERE     
      (DOCDATE BETWEEN @Fromdate AND @Todate)
   GROUP BY 
       DOCDATE, DOCID, CUSTNMBR, CUSTNAME, DOCAMNT
   HAVING      
       (CUSTNAME = @Custname) AND (DOCID IN (@DocID))
GO

and use the stored procedure as my dataset…the SSRS report does not pull anything. It only pulls data with a single DOCID value.

Would anyone be able to explain why that is happening?

Thank you in advance!

Answer 1

When you use IN it looks at a set and not a single string expression. Because of this you need to implement a function such as CsvToInt to return a table.

IN expects an array not a variable, someone asked a very similar question which will definitely help you: tsql IN not working properly if passed as parameter

The gist of it is simply writing a function that returns a table.
