[GRASS-user] SQL statement as input for v.surf.rst

[Ulrich Leopold]

Dear all,

how would I use an SQL statement correctly as shown in the following command:

v.surf.rst input="|SELECT precipitation FROM meteo_stations \
                 WHERE date='2005-10-01'" zcolumn=elevation \
                 output=prcp_2007-10-01

Best regards,
Ulrich
