> I have two tables A(colA, col2, col3), B(colB, col3, col5)
> If i join them in a subquery on A.colA = B.colB i can select the non duplicate columns, but i cannot create a view (col3 is duplicate, but not selected)
>  
> {code:java}
> create view testview as select
> tmp.colA, tmp.col2, tmp.colB, tmp.col5
> from (
> select * from A left join B
> on (A.colA = B.colB)
> )
> {code}
>  
>  
> This works:
>  
> {code:java}
> select
> tmp.colA, tmp.col2, tmp.colB, tmp.col5
> from (
> select * from A left join B
> on (A.colA = B.colB)
