It is not unusual to have multiple instances of the same logical TurboIMAGE database; for example, dbname.groupa and dbname.groupb where groupa and groupb represent different companies or divisions or years. Now, suppose you want to attach both databases to the same DBE. The trick, documented in the HP IMAGE/SQL Administration Guide, is to "... specify an alternative owner at attach time".

For example,

attach dbname.groupa.acct with owner=groupa

attach dbname.groupb.acct with owner=groupb
