[Gvsig_english] Definition query

[ernesto sferlazza]

Hi all
When I work with ESRI ArcMap, often I use the "definition query" that allows
to use a subset (based on a sql query) of a larger shapefile without the
need of exporting the same subset in a new shapefile. In this way, in the
map views, I can refer many times to the same shapefile in the archive
without "overpopulate" the geographic database (e.g. when I need to work
separately with the layer of the Agrigento Province, I refer to the
"PROVINCIE_ITALIA" layer and I perform a Definition Query ("select from
"Provincie_italia" where Provincia = "Agrigento" ) instead of performing the
same selection and exporting it to a new theme.
I have not found this feature in GVSIG, so I wish to find that in a future
version of GVSIG
Thanks
Best Regards
