Hi Fernando,
I'm glad to hear it!
I hope someone will compile the 4.4.0 version with this new oracle support ... for windows.
If someone compile it as said above, I'd be glad to know about it.
Good works!!
Nicolas
PS: Thanks to Jane Gehan and Kari A. Geurts who helped me solve my posting problem.

Hi Javier,
Yes, "the querys" are working correctly now, I tested the query functions with cgi mode an mapscript functions and both kinds work correctly.
The query support is finished, now I'm working with others supports for the oraclespatial. So I believe that the querry support will be include in the next version of mapserver.
Thank's for the help.
