# v.db.droptable

Removes existing attribute table of a vector map.

=== "Command line"

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

    Example:

    ```sh
    v.db.droptable map=name
    ```

=== "Python (grass.tools)"

    *grass.tools.Tools.v_db_droptable*(**map**,
        **table**=*None*,
        **layer**=*"1"*,
        **flags**=*None*,
        **verbose**=*None*,
        **quiet**=*None*,
        **superquiet**=*None*)

    Example:

    ```python
    tools = Tools()
    tools.v_db_droptable(map="name")
    ```

    This grass.tools API is experimental in version 8.5 and expected to be stable in version 8.6.

=== "Python (grass.script)"

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

    Example:

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

## Parameters

=== "Command line"

    **map**=*name* **[required]**

    &nbsp;&nbsp;&nbsp;&nbsp;Table name (default: vector map name)  
    **layer**=*string*  
    &nbsp;&nbsp;&nbsp;&nbsp;Layer number or name  
    &nbsp;&nbsp;&nbsp;&nbsp;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.  
    &nbsp;&nbsp;&nbsp;&nbsp;Default: *1*  
    **-f**  
    &nbsp;&nbsp;&nbsp;&nbsp;Force removal (required for actual deletion of table)  
    **--help**  
    &nbsp;&nbsp;&nbsp;&nbsp;Print usage summary  
    **--verbose**  
    &nbsp;&nbsp;&nbsp;&nbsp;Verbose module output  
    **--quiet**  
    &nbsp;&nbsp;&nbsp;&nbsp;Quiet module output  
    **--qq**  
    &nbsp;&nbsp;&nbsp;&nbsp;Very quiet module output  
    **--ui**  
    &nbsp;&nbsp;&nbsp;&nbsp;Force launching GUI dialog

=== "Python (grass.tools)"

    **map** : str, *required*  
    &nbsp;&nbsp;&nbsp;&nbsp;Name of vector map  
    &nbsp;&nbsp;&nbsp;&nbsp;Or data source for direct OGR access  
    &nbsp;&nbsp;&nbsp;&nbsp;Used as: input, vector, *name*  
    **table** : str, *optional*  
    &nbsp;&nbsp;&nbsp;&nbsp;Table name (default: vector map name)  
    &nbsp;&nbsp;&nbsp;&nbsp;Used as: input, dbtable, *name*  
    **layer** : str, *optional*  
    &nbsp;&nbsp;&nbsp;&nbsp;Layer number or name  
    &nbsp;&nbsp;&nbsp;&nbsp;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.  
    &nbsp;&nbsp;&nbsp;&nbsp;Used as: input, layer  
    &nbsp;&nbsp;&nbsp;&nbsp;Default: *1*  
    **flags** : str, *optional*  
    &nbsp;&nbsp;&nbsp;&nbsp;Allowed values: *f*  
    &nbsp;&nbsp;&nbsp;&nbsp;**f**  
    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Force removal (required for actual deletion of table)  
    **verbose** : bool, *optional*  
    &nbsp;&nbsp;&nbsp;&nbsp;Verbose module output  
    &nbsp;&nbsp;&nbsp;&nbsp;Default: *None*

    &nbsp;&nbsp;&nbsp;&nbsp;Default: *None*  

    Returns:

    **result** : grass.tools.support.ToolResult | None  
    If the tool produces text as standard output, a *ToolResult* object will be returned. Otherwise, `None` will be returned.

    Raises:

    *grass.tools.ToolError*: When the tool ended with an error.

## 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:  

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