Bart, The Government of BC has an application which uses non-spatial filters in SLD documents to Mapserver, with an SDE back-end: http://openmaps.gov.bc.ca/imfows13/imf.jsp?site=idt Find Imagery --> Air Photos --> Search For Air Photos Zoom in to the resultant features, activate the "Centres" tool, and draw a box around a number of Air Photo centre points. This will show three separate SDE layers styled using an SLD with a filter (non-spatial), two of which have alternate symbolization and thus a more complex filter clause in the SLD.
Incidentally, the other imagery types (Orthophotos, Satellite Imagery, etc) are primarily backed by shapefiles, so are not relevant to this discussion. I did run into timeout problems getting the SLD to work when there were > 200 or so individual features that needed to be identified with the filter. I had been using a single PropertyIsEqualTo clause for each feature which I was able to change to a handful of PropertyIsBetween clauses due to the convenient sequential numbering of the ID values which I was filtering. This change allows the SLD filter to work quite well. Regards, John Fletcher Latitude Geographics Group Ltd.

My reasoning is that this is since the query-by-id mechanism will query ArcSDE for each item of the resultset and this just won't work. So can I safely conclude Mapserver on ArcSDE won't work well for non-spatial queries? I am using FastCGI already. Using cgi crashes as well, but after a longer period of waiting time (minutes).
