SQL & PL/SQL

I have a stored procedure which has an OUT parameter of table1%ROWTYPE.

In future we might have to add more OUT parameters of table2%ROWTYPE etc. But at any point of time only one will have values.

So instead of having table%ROWTYPE as OUT parameter, can I send these single row ( with variable values) in a cursor, so that declaration part atleast will not change.

Is it possible to select values from table%ROWTYPE variable into a cursor.

cursorOUT IS
SELECT * FROM varREC;

where varREC is table.ROWTYPE variable.

Or which is the better solution in this situation.

Thanks.
