Sorry, I think I haven't explained correctly.
I want the possibility that user can choice data to join, and in a view 
the join are "fixed".
I can make a view with states and population and user can ask this view 
but is user want ask data and sales for example he need another view. I 
want that user choice table that he need (states with geographyc 
information and join with anoter tables in database like population, 
sales, age, etc.
according to their needs, without intervention in "server side".

Make querys in a view needs create the view in "server side". Is for 
this question that data type in attribute table need a correct behavior
