v.db.droptable

Removes existing attribute table of a vector map.

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

Example:

v.db.droptable map=name

grass.script.run_command("v.db.droptable", map, table=None, layer="1", flags=None, verbose=False, quiet=False, superquiet=False)

Example:

gs.run_command("v.db.droptable", map="name")

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.
    Default: 1
-f
    Force removal (required for actual deletion of table)
--help
    Print usage summary
--verbose
    Verbose module output
--quiet
    Quiet module output
--qq
    Very quiet module output
--ui
    Force launching GUI dialog

map : str, required
    Name of vector map
    Or data source for direct OGR access
    Used as: input, vector, name
table : str, optional
    Table name (default: vector map name)
    Used as: input, dbtable, name
layer : str, optional
    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.
    Used as: input, layer
    Default: 1
flags : str, optional
    Allowed values: f
    f
        Force removal (required for actual deletion of table)
verbose: bool, optional
    Verbose module output
    Default: False
quiet: bool, optional
    Quiet module output
    Default: False
superquiet: bool, optional
    Very quiet module output
    Default: False

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
