[OpenLayers-Users] query features based on tabular attributes through WMS?

I see there is a GetFeatureInfo in the WMS specification, and it assumes a user clicking a point on the map that then sends an XY to the server.  I've also seen a CIA Factbook example for OL.   Is there any easy way to just query against a tabular attribute, rather than an XY?  Must I use WFS queries to accomplish this?

I noticed the thread at http://www.nabble.com/Zoom-to-feature--tf2203721.html#a6212900

The application I am working on stores GIS data in ArcSDE/Oracle.  ESRI ArcIMS displays WMS map services via its WMS Connector.  What I'd like to be able to do is only display map features that have a table attribute equal to a particular ID.  So in other words, I'd like to query the GIS data for features (individual shapes in a "feature class" vector data table in Oracle) that are equal to this ID, and display them on a map as WMS.  I know how to do this through ESRI software, but I'm not sure how I could do this via OL and WMS.

Any advice about this would be appreciated.

Thanks.
