## DESCRIPTION

db.describe displays table information. If parameter -c is used only column names instead of full column descriptions is given.

## NOTE

If parameters for database connection are already set with db.connect, they are taken as default values and do not need to be spcified each time.

## EXAMPLES

List column descriptions of table in SQLite database (note that this is the default setting)

    db.describe driver=sqlite table=hospitals \
       database='$GISDBASE/$LOCATION_NAME/$MAPSET/sqlite/sqlite.db'

    # or simply
    db.describe myarchsites

### DBF example

    db.describe -c table=hospitals database='$GISDBASE/$LOCATION_NAME/PERMANENT/dbf/' \
                driver=dbf
    ncols: 16
    nrows: 160
    Column 1: cat:INTEGER:11
    Column 2: OBJECTID:INTEGER:11
    Column 3: AREA:DOUBLE PRECISION:20
    [...]

    db.describe table=hospitals database='$GISDBASE/$LOCATION_NAME/PERMANENT/dbf/' \
                driver=dbf
