In Sybase IQ 12.5, user-defined data types (domains) were case sensitive in case sensitive databases. For example, you could create domains HIRE_DATE and hire_date. In Sybase IQ 12.6, domain names are case insensitive. Sybase IQ 12.6 returns an error if you attempt to create a domain with the same name as an existing domain except for case.
