Get rid of select from dual! Hah, the next thing you will suggest is that we convert to the metric system!
Marge: Now, I know you haven't liked some of my past suggestions, like switching to the metric system -- Abe: The metric system is the tool of the devil!

What you are casting is the single row and single column that you select from dual, but that single item is the result of casting a result set into a nested table or varray. In fact in Oracle 9, you can get rid of the select from dual, and for a function returning the varray/nested table write: select * from table(function_name); or, if TABX is a table with a column COLX select colx, function_name(colx) from TABX; You can play similar games with 8.1, but the SQL looks messier. You may then need to wrap one level of SQL inside an inline view to convert the whole thing into a flattened table.
