Subject: db.select in GRASS 6.0.0beta1
the options of the SQL select statement are limitated? I would like to
select of one field of a table and to add these valors with "SUM" but it
doesn't works, I write:
db.select -c sql="select sum(AREA) from parcela"
and I obtain an error in SQL parser statement...
Somebody can help me?
Thanks,

What does
v.db.connect -p parcela

The dbf driver functionality is limited (maybe we should change to

Ah: The sum() function is not available in the DBF driver.
But it should work connecting GRASS to PG or mySQL.
