If I have 2 attribute columns and I wish to change certain values, is it possible for the second attribute column to automatically update its values based on an expression?
Age | Status 10 | Child 14 | Child
If I change the
Age from 14 to 18, I would like the
Status to automatically change from Child to Adult, so it would look like the following:
Age | Status 10 | Child 18 | Adult
I must only be able to do this within QGIS and without the use of database functionalities such as PostGIS/SpatiaLite etc. I've looked at Value relations but that only seems to provide drop-down box for the user to select the relating columns. I've also looked at Relation Reference but it won't allow me to select a "Relation" (not even sure what Relation Reference actually does).
I am using QGIS 2.2.
