Hello,
I'm having an annoying problem here..
My query looks like       " where Month(ADM_Date) in (@MONTH)"
The Param @Month type is  Integer - setup to allow multiple values!

when I pass 1 or 2 indvidually , it works fine...
when I pass 1, 2 ,3 ,4 etc...  it fails " error: The Value provided for the report paramter 'Month' is not valid for its type"

when I change its type to TEXT, of course I get an error !

Any thoughts?

Thanks

Hi,

Looks like '1,2,3' is a string ...

Is there any chance for you to pass '''1'',''2'',''3''' instead?

If you you just have to say there CAST(Month(ADM_Date) AS VARCHAR(2)) in (@Month)


That's my first impression....

Good luck

Note that I set 2 single quotes surrounding 1, 2, 3 to have a proper string in single quotes...

Hi,

Please verify that the query you're executing after replacing the param looks like

WHERE CAST(Month(ADM_Date) AS VARCHAR(2)) in ( '1', '2', '3' )

If looks like this and doesn't return anything, I'll try to figure out some (if possible)


Cheers.

Sorry,


Use this


WHERE CONVERT(varchar(2), Month(ADM_Date), 126) in ( @Month )

Open in new window

CAST and dates are tricky...

Use CONVERT and 126 to convert it to ISO-8901

Hope this works

If your query comes from store proc you have to use like split function to work for multivalue paramenter (that is the work around I know for reporting services).  refer to the link

Hi,

I know what happens,

I was preparing the query like it was for dynamic SQL, but it's not going to work like this I'm afraid...

Let me think plan b.

Hi

There are several things that are unclear to me in your post.

You seem to be using T-SQL in SSRS IN(@Month) and that normally works very well but could you clarify how you supply the values?
1) Do you type them in? If yes then remember to type value hit enter and type another value (no commas, single quotes etc!)
2) If you provide values using dataset then make sure value is set correctly in the parameter.

I don't understand the bit about dynamic SQL :) So far I can see you try to use standard SSRS parameter filtering.

Hope that helps
Emil

Hi,

I think @Hadush solution is a valid one, but if for any reason you cannot create another function to return the values in the list, you can try with dynamic SQL as I told you.

In this case, using you don't need to convert anything to string.

I don't like much this solution because of the dynamic SQL, but it works.


Cheers.
DECLARE @sql VARCHAR(MAX)
-- DECLARE @Month VARCHAR(50) SET @Month = '1,2,3'

SET @sql = 'SELECT  ... ' -- Your Query
SET @sql = @sql + ' WHERE Month(ADM_Date) in ( ' + @Month + ' )'

EXEC (@sql)

Open in new window

Thank you for stepping in...yes true..I'm not intending to use any dynamic SQL
and I'm not getting the values out of a query.

I've another report that when you click on a field, takes you to another report and passes the value that I already assigned.

see attached screen shot..

can;t use the enter, or without commas...

Hi

That is much clearer now. How do you provide values for month? In the screenshot you have static value?
If you use expressions in there Iand want to join values into multi-value parameter array try using join function. I will have a go with that and let you know my findings.

Regards
Emil

Did I use Join? Hmmm I should have said Split

Here is the expression I used to pass 10, 20 into subreport
=Split("10|20","|")

Hope that points you in the right direction
