Great article, it was very helpful for me…
Just a litle error (I think it's a typo): at step number 6 of “Integrate with SQL Reporting Services” It is not “Create a DATASOURCE for the report called….” It must be Create a DATASET instead.

Thanks,
Lara

An error occured during local report processing.
An error has occured during report processing.
The Value expression for the query parameter '@Multi' contains an error: The expression that references the parameter 'Type_Of_Aid' does not exist in the Parameter collection. Letters in the names of parameters must use the correct case.

This was a really helpful tip. I used the following logic to parse out duplicates from the string:

First, I added a parameter that works just like the TrimSpace parameter: @removeDuplicates bit

Then I added the following logic after the @TrimSpace line and before the END:

IF @removeDuplicates = 1
-- If removing duplicates is requested, check to see if entry is
-- a duplicate
IF EXISTS (SELECT 1 FROM @Table WHERE Val = @Val)
-- If it is, do nothing
SET @Val = @Val
ELSE
-- If it isn't, then add it to the table
INSERT INTO @Table ( [Val] )
VALUES ( @Val )
ELSE
-- If removing duplicates isn't requested, add it to the table
INSERT INTO @Table ( [Val] )
VALUES ( @Val )

Duplicates: Since you are building @Table in a loop, you can return SELECT DISTINCT, no?

Seems to me that a string join in SSRS and all that logic in SQL amounts to "really an array constructor/deconstructor too."

If you know you're only working with strings, you should be able to use
SSRS (deconstructor):
="<([" & Join(Parameters!FC.Value, "])>,<([") & ")]>"
(Any weird delimiter you can expect to _not_ be a substring of 99.99% of the values)
and then in SQL, you don't need to reconstruct:
WHERE @Param Like '%<([' + Col_Name + ')]>';

If they are not strings, well, just wrap Col_Name in whatever formats the value the same way SSRS does.

EXCEPT, it didn't work, though I think it's not my fault. Because the third time I tried it, Visual Studio crashed, and now crashes _every_ time I attempt to preview the report, with yesterday's version!

how can I pass multivalued parameters in my ssrs expression. I dont have any problem with the query. I used the same approach to get the data from the query. That is I have used function in my query. I have problem in my expression. If I select more than one value I am getting error.

Example:
iif(Fields!myfield.value = Parameters!myparameters.value(0),"0","")
I tried using Join, Instr its not working. Can you please help me out with this problem

I can get a fairly simple query to work with this but when there are multiple Joins in a query it doesn't return any results. I do appreciate tip as it's really got me thinking and I know I can't be far from a solution.

Awesome! You are the man. Says right in the book: The data source cannot be a stored procedure. Reporting Services does not support passing a multivalued parameter array to a stored procedure.
but you got me past that! thank you!!!

This is fine but having two problem.

1. Join cause post back (re-filling of dataset)

2. Execution time exceeds
