well grass not see joined tables. the only way as I thing is to use SQL 
command CREATE TABLE nova AS
SELECT a.cat ..... FROM a INNER JOIN b ON .......;
nad reconnect vector to nova table (a.cat MUST be in SELECT section)
I use it very ofen but... on PgSQL. I'm not sure if CRATE TABLE AS works 
on mysql
