[QGIS-Developer] Factorizing a dbf

[Paolo Cavallini]

Hi all,
I have a large shp with a number of repeated strings, and I'd like to
refactor it replacing strings with a numeric code. I have found a
Processing alg that does it, creating a new file each time, which is
cumbersome; moreover, the alg apparently changes field type, adding
decimals to reals. Of course I could create a CASE statement, but this
is also cumbersome.
Is there a more straightforward way?
Thanks.
