T,
To get the column length, you can use the export/add geometry function
in fTools, which will create a copy of the dataset (as a shapefile) with
an additional length field (or it will populated the length field if it
already exists). From this you can use the compute basic statistics
function to get the sum of the field...
Hopefully that's what you are looking for?

HI everybody
i hope someone can help me with this:
in a poly-line vector layer, which is obviously built of several
festures, how can i add a column of LENGTH to the attribute table?
then how can i SUM all of it?
