Do you mean making a layer queryable via GetFeatureInfo WMS requests? 
Simply setting a query template in your layer definition in the mapfile
makes it queryable in the WMS Capabilities, and then you can use it in a
GetFeatureInfo request.

GetFeatureInfo supports up to three INFO_FORMATs in the latest version
of MapServer depending on your configuration:

- INFO_FORMAT=text/plain - List feature ids and attibute names value in
plain text format

- INFO_FORMAT=application/vnd.ogc.gml - returns selected features in
GML  format.  You also have to set "DUMP TRUE" in your layer to enable
this.

- INFO_FORMAT=text/html - Uses the MapServer query template to produce
query results in HTML format.  Works exactly like the traditional
mapserv CGI query templates.

SLD and STYLEs are not supported by the current version.  If I properly
understood what you're trying to do, then it would seem that defining
separate layers would be your best option for now.
