How to query based on a parameter?

Last Modified: 2013-11-19
I have a .jsp pages that returns an Oracle query, works great.

I want the page to load by querying everything, then the user clicks a button and this filters the query.

So I need a variable, sourcesToQuery, on startup will be ('PRD','CLI','MEM',CLM',PCLM',PRV')

so the query will say

where subject_area in <%= sourcesToQuery%>

When they click the Claims button, then
sourcesToQuery = ('CLM','PCLM')

so something like

onLoad: set sourcesToQuery =  ('PRD','CLI','MEM',CLM',PCLM',PRV')

then when they click on the Claims button, it filters by sourcesToQuery in ('CLM','PCLM')

I know what I want to do but no idea how to do it. I am looking at other .jsp files that use parameters but can't get it working.

Below is the entire page, it works great if I don't try to filter
