Hi,
using 6.4.1, I imported a vector shape file which includes a tables.
This table got a "cat" column by grass (which I don't need, I think)
and already has a "key" column. In addition, I have got another table
which also has a "key" column. Using both "key" columns, I want to
combine both tables. How can I do that? I was able connect, as a
second layer, the additional table to the vector data using the "key"
column but then as far as I can see it is not really connected to the
first table.
I guess this is a standard procedure but I was not able to find the solution.
Thanks
Sebastian
Sebastian -
I think you're asking to connect two tables to the same map?
The two tables need to refer to the same features, and you use v.db.connect
Note that you can specify a different name for the key column using the
key= parameter.
Cheers,
Richard
