How to query based on a parameter?

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

I don't know what exactly you means, but js getURLParam function may help you
it can read URL and parameters from current URL.....
<script language="javascript">
function getURLParam(strParamName){
  var aParam;
  var strReturn = "";
  var strHref = window.location.href;
  if ( strHref.indexOf("?") > -1 ){
    var strQueryString = strHref.substr(strHref.indexOf("?")+1);
    var aQueryString = strQueryString.split("&");
    for ( var iParam = 0; iParam < aQueryString.length; iParam++ ){
      aParam = aQueryString[iParam].split("=");
      if (aParam[0] == strParamName){
        strReturn = aParam[1];
  return unescape(strReturn);

In this case, I'm not getting the parameters from the URL (but perhaps I have to do it that way).

a. I want to startup my page (query) by using this variable:
           where subj_area_cd = sourcesToQuery

          and sourcesToQuery = ('PRD','CLI','CLM','MEM','PCLM') which is set in onLoad (or something like that)

    so - how do I set the variable sourcesToQuery on startup ? The user comes in with just the URL (no params)

          - then if they click the "Claim" button, I set sourcesToQuery = ('CLM','PCLM') and re-query the page.

Since I am totally new to this, maybe I'm off track.

Based on what you are saying, and strictly using parameters, the starting URL should be

http://www.myWebPage.org?SOURCES=('PRD',CLI',MEM','CLM',PCLM'), so I'd have to grab the parm and use it in my where clause

then when they click the Claim button, the URL says ?SOURCES=('CLM','PCLM')

It makes sense to me that after clicking the claims button the URL looks like this: http://www.myWebPage.org?SOURCES=('CLM',PCLM')

but it seems goofy to me the the starting URL would be http://www.myWebPage.org?SOURCES=('PRD',CLI',MEM','CLM',PCLM') - no one could remember that . . . although they could bookmark it . . .

hope I'm making sense . . .

this is what I got as the solution from a colleague here:

where s1.stus_nm = 'active' and s1.subj_area_cd in (
        <c:when test='${param.filter == "clientprod"}'>

        <c:when test='${param.filter == "memidm"}'>
            'MEM','IDM') and s1.srce_sys_cd <> '141'

        <c:when test='${param.filter == "medd"}'>
            'MEM','PCLM') and s1.srce_sys_cd in ('140','141')

        <c:when test='${param.filter == "claim"}'>
        'CLM','PCLM') and s1.srce_sys_cd <> '140'

        <c:when test='${param.filter == "prov"}'>
