Using Large-Object Data in Typed Tables

Use the BLOB or CLOB instead of BYTE or TEXT data types when you create a typed table that contains columns for large objects. For backward compatibility, you can create a named-ROW type that contains BYTE or TEXT fields and use that ROW type to re-create an existing (untyped) table as a typed table. Although you can use a ROW type that contains BYTE or TEXT fields to create a typed table, such a ROW type is not valid as a column. You can, however, use a ROW type that contains BLOB or CLOB fields both in typed tables and in columns.
