DESCRIPTION

30       v.db.dropcol  drops  a  column  from the attribute table connected to a
31       given vector map. It automatically checks the connection for the speci‐
32       fied layer. v.db.dropcol omits to delete the 'cat' column which is rel‐
33       evant to keep the connection between vector map and table.
34

NOTES

36       v.db.dropcol is a front-end to db.execute to allow easier  usage.   The
37       existing database connection(s) can be verified with v.db.connect.
38

EXAMPLES

40       Dropping a column:
41
42       v.db.dropcol sentiero_brenta_points column=slope
43       v.info -c sentiero_brenta_points
