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

[Bart van den Eijnden (OSGIS)]

Hi Mike,

you can do this using SLD WMS.

The only thing you need to is set up a Styled Layer Descriptor XML, and 
include in your GetMap url for instance using SLD_BODY (inline) or SLD 
(access using a url). In the XML you also need to define how you want 
your selection to be symbolized.

Best regards,
Bart

Is there any easy way to just query against a tabular attribute, rather than an XY?  Must I use WFS queries to accomplish this?

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.
