I am working with QGIS and I have a table with several columns, some of them I defined as drop-down columns. In the next step I would like to define certain specifications. For example: If column A is "positive", then "not funded" must be selected in column B. I am not very familiar with Python, SQL and so on.

Welcome to Geographic Information Systems! Welcome to GIS SE! We're a little different from other sites; this isn't a discussion forum but a Q&A site. Your questions should as much as possible describe not just what you want to do, but precisely what you have tried and where you are stuck trying that. Please check out our short tour for more about how the site works– Ian TurtonCommented Mar 25, 2022 at 9:57

Well, what have you tried? Have you had a look at the documentation?– ErikCommented Mar 25, 2022 at 10:02

QGIS has an if function : "if(condition,result_when_true,result_when_false)" or a "CASE" fonction. I suggest you have a look at the attribute form (docs.qgis.org/3.22/en/docs/training_manual/create_vector_data/…) and try to implement your condition there, then to update your question if you get stuck update– J.RCommented Mar 25, 2022 at 10:14

1I think OP is asking "If I choose positive in col1, only the choice not funded should be available to choose from in col2". If you are see: gis.stackexchange.com/questions/416327/…– BeraCommented Mar 25, 2022 at 14:23
