So I tried the exact command you used on Windows 8, GRASS GIS 7.0.0 and
7.0.1 and it works for me. The column names are:
db.describe -c table=KavelsGemeente
ncols: 19
nrows: 136
Column 1: cat:INTEGER:20
Column 2: OBJECTID:INTEGER:20
Column 3: KAVEL_NR:CHARACTER:50
Column 4: KOPER:CHARACTER:50
Column 5: PRIJS:CHARACTER:50
Column 6: VERKOOPTEK:CHARACTER:50
Column 7: DATUM:CHARACTER:50
Column 8: HUISNUMMER:CHARACTER:254
Column 9: KOPER_NAAM:CHARACTER:50
Column 10: STRAATNAAM:CHARACTER:50
Column 11: HYPERLINK:CHARACTER:100
Column 12: BOUWJAAR:CHARACTER:4
Column 13: ERFPACHTCA:DOUBLE PRECISION:20
Column 14: PERCEELPRI:DOUBLE PRECISION:20
Column 15: ERFPACHT_1:DOUBLE PRECISION:20
Column 16: PERCEELP_1:DOUBLE PRECISION:20
Column 17: OPPERVLAKT:DOUBLE PRECISION:20
Column 18: SHAPE_AREA:DOUBLE PRECISION:20
Column 19: SHAPE_LEN:DOUBLE PRECISION:20
So I am not sure what to do about it.
Anna
