...I mean: how to get an table entry for every vector objects Id? (every
geometry object has an unique id)

Yes, thanks,
but how to force that every single geometry object (of one kind) gets an
entry?

(just to mention: And why aren't those commands reachable in an useful
order? One always has to check whether the table are built, go and add a
table, on another place set connection, on another place load up
cats...alway confusing and lots of clicking in the gui)

Hi all,
I think I am not the only one having problems with getting the
connection "vector geometry features" - "attribute table" (for me its
a sqlite db at the moment). ;-)
So I wonder how is the default way to deal with vector layers to
establish a metadata table to each geometry object?
Normally, categories are added and a table is automatically created at
vector import, or, by default, at digitalisation. But some modules do
not create a table as they wouldn't know what to put in it (and a
table with just cat values is not very useful as such).
I always have the problem that the table is empty. And adding
category is not enough to add an entry for every geometry object...
well.
After adding the category, you have to upload it to the table with
v.to.db.
If you do not even have a table connected to the map, you can run the
script v.db.addtable which creates the table (by running an SQL query)
and then adds the category values to it (with v.to.db).
