OK Frank and Guillaune
Here are more precisions:
1. I work with OSGEO4W with plugins oci.
2. My datatable is a table Oracle spatial with a column geometry.
3. If I launch ogr.exe with -sql select * from myTable or with -sql
select * from myTable -spat XMIN YMIN XMAX YMAX => the result is the same.
That's the reasons why I don't understand.
Do you have a example?

Guillaume, what's your database ?
Thanks you very much

Folks,
The only thing I might add is that -spat does not actually clip
the returned geometries. It returns all features whose geometries
touch the selection region but it returns the geometries intact, not
clipped.
Lionel, I think you will need to supply a specific example that
is not working for us to followup. I will say that the spatial
filtering is done by the individual driver and there is always the
chance that some drivers do not do it properly.
Best regards,
