Hi, I have a vector layer FOO which is linked to two tables in layers 1 and 2. The categories for each vector element are different in layer 1 and (e.g. a certain area may have the cat value "51" in layer 1 and a cat value of "42" in layer 2). Let's assume that layer one has a VARCHAR column containing the names of the region (e.g. database_layer_1: 51,"Wolfenstein" database_layer_2: 42 )
If a new VARCHAR column is added to layer 2 by v.db.adcol, how can the the names from layer 1 be copied into it? [Goal: database_layer_1: 51,"Wolfenstein" database_layer_2: 42,"Wolfenstein" ] Unfortunately, v.db.update seems only to work within one layer. An UPDATE/SELECT SQL-statement will not be possible unless a table can be produced which holds the categories for both database layers for each geometry element. How can this be solved ?
