Hi
I need a function which are able to return the underlying tables to a view.
If I have a view which is a selection from field1 and field2 from table1
and field1 and field2 from table2.
How can I make a selection which returns the relation for the fields in a
way so I am able to se which field belongs to which table.
SELECT * FROM pg_views WHERE viewname='TestView' will return the schema
and the definition for me.
SELECT * FROM pg_class WHERE relname = 'TestView' will return some oids etc.
SELECT * FROM pg_attribute JOIN pg_class ON attrelid = pg_class.oid AND
pg_class.relname='TestView' will return the fields including oids etc.
But I just cant find out how to find the tables for each field.
I hope someone are able to help me with this problem.
Regards
Jan Andersen
