What, exactly, is your requirement? It has been mentioned that you are creating a string, not a column reference for the declared type, which explains your current output. Using execute immediate may not work as that involves a context switch and once that happens the SQL session created to execute your dynamic statement has no 'knowledge' of empRowType, much less its contents.

Knowing your 'marching orders' will help us tremendously in assisting you.
