Hi, maybe the field refactor alg' with a "replace()" mixed with a attribute(get_feature , etc...) looking in the reclassification table could do? Cheers Régis 2018-01-22 13:18 GMT+01:00 Luiz Motta : > Hi Paolo, > > A possible insight can be this: > - Create a table with

Re: [QGIS-Developer] Factorizing a dbf

Hi Paolo, A possible insight can be this: - Create a table with two columns: 'string from SHP' and 'respective number code'. - In SHP create the Union with the table above. - Use Calculator for populate the new field in SHP with value of code. Good lucky. 2018-01-22 9:18 GMT-02:00 Paolo

[QGIS-Developer] Factorizing a dbf

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
