I'm currently developing a postgres DB backend to my current project and have
the following problem. If I execute a query I need to know the table the
returning fields belong to. For example :
SELECT x.y, z.y from x, y where x.key = z.key
The problem with the above is that I get back 2 fields called 'y' and have no
way of knowing from which tables they've come from. The query is arbitrary so I
cannot assume table order in the SQL statement (Icannot assume anything about
the query except that it's a SELECT).
What information from the 'C' or 'C++' APIs can help ?
Is there is a way of identifying the originating tables ?
Thanks
Philip
