hello all, I tried to make calculations between attributes and insert the
results in new columns, in vector files, but can not find an easy way to do
also is very difficult to edit or delete an attribute not know if I'm doing
something wrong or is it something program, which surprises me the level
Ricardo,
This is not an answer to your question but rather a question to the
list. Can v.db.update take as values a formula using data from other
collumns? Or would I need to use db.execute to do something like
new_column = col_A + col_B
