Hi,
I tooked a look into the manual for the command v.db.connect. But I’m not sure how it really works. I had imported this file:
#‘X_COORDINATE Y_COORDINATE’
L 2 2
3400630.04 5718486.603
3400639.238 5718515.776
6 1
9 1
L 2 2
3400639.238 5718515.776
3400648.641 5718546.057
6 182
9 182
L 2 2
3400648.641 5718546.057
3400665.041 5718562.99
6 181
9 181
into the vector koord_grass2
I check that there is no connection
GRASS 6.2.1 (luenenxy):~ > v.db.connect -p map=koord_grass2
ERROR: Database connection for map <koord_grass2> is not defined in the DB-file
Then I connect the vector to a table using layers 6 and 9
GRASS 6.2.1 (luenenxy):~ > v.db.connect map=koord_grass2 table=GIS_Darstellung.dbf key=SECTION_ID layer=6 -o
WARNUNG: Die Tabelle <GIS_Darstellung.dbf> existiert nicht in der Datenbank
<$GISDBASE/$LOCATION_NAME/$MAPSET/dbf/>.
WARNUNG: The table <GIS_Darstellung.dbf> is now part of vector map
<koord_grass2> and may be deleted or overwritten by GRASS modules
WARNUNG: Select privileges were granted on the table
GRASS 6.2.1 (luenenxy):~ > v.db.connect map=koord_grass2 table=GIS_Darstellung.dbf key=SECTION_ID layer=9 -o
WARNUNG: Die Tabelle <GIS_Darstellung.dbf> existiert nicht in der Datenbank
<$GISDBASE/$LOCATION_NAME/$MAPSET/dbf/>.
WARNUNG: The table <GIS_Darstellung.dbf> is now part of vector map
<koord_grass2> and may be deleted or overwritten by GRASS modules
WARNUNG: Select privileges were granted on the table
And receive these warnings??
Why this WARNING: Die Tabelle <GIS_Darstellung.dbf> existiert nicht in der Datenbank (that means that the table is not in the DB). Actually the file is there. How should I write the path rightly?
Does anybody know better tutorials on the web?
Thanks

Use the 'database=' parameter to give the path to the directory where
your dbf file lies.

Better than what ?
Check the GDF tutorial:

Hi Moritz,
thanks for your comments, I'm gonna try that.
I meant exactly better than GDF's tutorial.
Could you be more precise on what you need in addition to that tutorial. ?

Fisrt of all, let's try to keep this on the mailing list so that other's
may profit of it.

If you get by with Italian, you can check this:
http://www.ing.unitn.it/~grass/docs/tutorial_60/italiano/esercitazioni.htm
(an english version is foreseen).
There is also a "visual tutorial" for MacOSX and a slightly older
version of GRASS, but still maybe useful:
http://www.public.asu.edu/~cmbarton/files/grass_osx/Grass-6-Visual-Tutorial.pdf
Then there is always the book:
http://mpa.itc.it/grassbook2/
of which the third edition should come out in a few months.
I have the impression GRASS is more powerful than ArcView but on the
other hand these many possibilities leave many questions open for a
beginner...
GRASS is definitely more powerful than ArcView. It is in the same league
as ArcInfo / ArcGIS...

Thanks.
I think the second reference will help a lot as I am also new to UNIX/Linux. Actually, today I wanted to try v.db.connect via GUI as my trials yesterday were not so successful.
