SELECT dblink_oraconnect('scott/[EMAIL PROTECTED]');
SELECT * FROM dblink_ora('SELECT ename, sal FROM emp')
AS (ename text, sal text);The problem is: If I wanted to do a
SELECT * FROM dblink_ora('SELECT * FROM emp');
It won't work because dblink_ora returns SETOF RECORD. If could define a type representing the remote data structure.
However, my question is: Is there a way to implement it in a way that does not depend on the remote data structure?
Is there a way to get rid of the AS without having to define a type?
Maybe somebody can provide me some information about that or point to me to some material about this topic.
If we had a solution for that, we could go ahead and do some basic OLAP operations. Imagine we had a cube generated by the means of SQL.
We could do
SELECT * FROM some_olap_operation(cube, ...);
without worrying about the elements in a certain dimension which should be displayed in the x-axis (as columns).
If there was a nice workaround or a solution I'd be really happy :).

Hans
