Thats exactly the problem: It shows nothing.
None of my lines has any cat.
Well, then you need to add them with 'v.category option=add'

Hi Moritz,
thanks for reply and this detailed explanation.
I try to report my problem with an example:
reset to initial point
v.db.connect -d map=my_li...@achim
db.droptable -f table=testtable
my_lines:
| Type of Map: vector (level: 2)
|
| Number of points: 0 Number of areas: 0
| Number of lines: 2326 Number of islands: 0
| Number of boundaries: 0 Number of faces: 0
| Number of centroids: 0 Number of kernels: 0
| Map is 3D: No
| Number of dblinks: 0
Number of nodes: 2410
(with grass65 wx-gui)
v.db.addtable map=my_li...@achim table=testtable
Using user specified table name: testtable
Creating new DB connection based on default mapset settings...
Creating table with columns (cat integer)
The table <testtable> is now part of vector map <my_li...@achim> and
may be deleted or overwritten by GRASS modules
Select privileges were granted on the table
Reading features...
Updating database...
0 categories read from vector map (layer 1)
0 records updated/inserted (layer 1)
Current attribute table links:
layer <1> table <testtable> in database
</home/achim/grass/sqlite_db> through driver <sqlite> with key <cat>
Vector map <my_li...@achim> is connected by:
?here no records updated/inserted
Probably none of your lines have categories. What does v.category
my_lines option=report show ?
