.SH SYNOPSIS
\fBv.db.droptable\fR
.br
\fBv.db.droptable \-\-help\fR
.br
\fBv.db.droptable\fR [\-\fBf\fR] \fBmap\fR=\fIname\fR  [\fBtable\fR=\fIname\fR]   [\fBlayer\fR=\fIstring\fR]   [\-\-\fBhelp\fR]  [\-\-\fBverbose\fR]  [\-\-\fBquiet\fR]  [\-\-\fBui\fR]
.SS Flags:
.IP "\fB\-f\fR" 4m
.br
Force removal (required for actual deletion of table)
.IP "\fB\-\-help\fR" 4m
.br

.IP "\fB\-\-verbose\fR" 4m
.br
Verbose module output
.IP "\fB\-\-quiet\fR" 4m

.SS Parameters:
.IP "\fBmap\fR=\fIname\fR \fB[required]\fR" 4m
.br
Name of vector map
.br
Or data source for direct OGR access
.IP "\fBtable\fR=\fIname\fR" 4m
.br
Table name (default: vector map name)
.IP "\fBlayer\fR=\fIstring\fR" 4m
.br
Layer number or name
.br
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.
.br
Default: \fI1\fR
.SH DESCRIPTION
\fIv.db.droptable\fR removes an existing attribute table from a
given vector map linked at given layer. If the \fB\-f\fR force flag is not
given then nothing is removed.
.SH NOTES
\fIv.db.droptable\fR is a front\-end to \fIdb.execute\fR to allow easier usage.
.PP
The existing database connection(s) can be verified with \fIv.db.connect\fR.
.SH EXAMPLE
Removing attribute table connected to layer 1:
.br
.br
.nf
\fC
g.copy vect=roadsmajor,myroads
v.db.droptable myroads
v.db.droptable myroads \-f
v.db.connect \-p myroads
\fR
.fi
