My questions are: 1. what is multi_byte database and what is single_byte database? 2. how to create database use multi_byte? 3. how to create database use single_byte? 4. how to check database is multi_byte or single_byte? 5. any document relate to that? Thanks. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com -- //www.freelists.org/webpage/oracle-l
