U need to create ur own function. Its not available. u can use following query

select column_name
from all_tables
where table_name = p_table_name
and owner = p_owner_name;

I don't know PL/SQL Developer but I can't imagine a tool that does not know cursor.

I transfer this thread to SQL Client Tools forum.

I meant this may not be the syntax.
There may be another syntax.
But there surely is a way to declare a cursor.
Did you check in the documentation?
Otherwise, wait for someone.
