Hi,
I'd like to replace multiple vector lines with ID == 42 with one new one, and
keep the attributes (date, year, name) from one of the replaced/removed lines.
I'm able to create my one new line with:
echo "L 2 1
-273157 -994455
-255458 -989423
1 100000" | v.edit -n tool=add map=test input=-
I'm not sure how to copy over the relevant attributes from one of the lines
(first, last, doesn't matter) that has the relevant ID.
Once I do that, I think I know how to delete the lines I don't want, but I'm
not sure I'm doing it correct. It seems I have to run two commands to delete
the lines from both the vectors (when displaying) and the database (when
querying). I'm doing this:
v.edit map=test tool=delete where="ID == 42"
db.execute sql="DELETE FROM test WHERE ID == 42"
Can anyone help with the middle step?
Thanks,
-k.
