[MS4W-Users] DrawQuery with Oracle Spatial -RFC 52(?)

[Jeff McKenna]

Pano,

I think you should send this message to the mapserver-dev email list 
(subscribe at http://lists.osgeo.org/mailman/listinfo/mapserver-dev). 
You may have found a valid issue in the oracle driver for MapServer, 
which may have been caused by the RFC 52 changes, and the best way to 
ask is to ask the MapServer devs through that list.  Also, in your 
message there, instead of referring to 'ms4w v3' or 'ms4w v2.3.1' be 
sure to mention 'MapServer 5.6.3' (for ms4w 3.0-beta11) and 'MapServer 
5.2.1' (for ms4w 2.3.1) instead.  Thanks.

-jeff
