v.db.droptable [-f] map=name [table=name] [layer=string] [--help] [--verbose] [--quiet] [--ui]

    Print usage summary

--verbose
    Verbose module output

--quiet
    Quiet module output

--ui

  Parameters:

map=name [required]
    Name of vector map
    Or data source for direct OGR access

table=name
    Table name (default: vector map name)

layer=string
    Layer number or name
    Vector features can have category values in different layers. This number determines which layer to use. When used with direct OGR access this is the layer name.

DESCRIPTION
v.db.droptable removes an existing attribute table from a given vector map linked at given layer. If the -f force flag is not given then nothing is removed.

NOTES
v.db.droptable is a front-end to db.execute to allow easier usage.

The existing database connection(s) can be verified with v.db.connect.

EXAMPLE
Removing attribute table connected to layer 1:

g.copy vect=roadsmajor,myroads
v.db.droptable myroads
v.db.droptable myroads -f
v.db.connect -p myroads
