[Gvsig_english] Definition query

[Wolfgang Qual]

Hi Ernesto,
well, I asked for this feature in the past, but developers were sceptical about the usefulness of it: --> http://runas.cap.gva.es/pipermail/gvsig_internacional/2007-October/000851.html

Best regards,
Wolfgang

> 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
