Question : I need to send a comma delimited string to a stored procedure to run an in(@parameter) query

I am running a report from reporting services using a sp (i have attached the code for the sp in the code section) i n reporting services there is a parameter of availible vendors in a multiple select drop down box which sends data to the @vid1 param. The @vid1 param is used in a in statement see the code. The @category is the same scenario. I have never done this with a stored procedure before using an in statement does not seem to work. I keep getting the following error conversion failed when converting the varchar value '363,390' to data type int. How do i change the attached code to work with a comma delimited string in a parameter to be used within a in statement.

Answer : I need to send a comma delimited string to a stored procedure to run an in(@parameter) query

The suggestion is to check and see what exactly you want to extract and to make sure that your select statements are doing that. I already pointed you that the function is using the @cost1 whithout any affect on the output so the problem resides in the logic you are using. I don't know aht are you after and what data you have, this should be for you to figure out.

However the technique for the comma separated values that I gave you works and I implemented it correctly to the code I was given. It is your task to correct the code.
