Is length of rowid in Oracle 11g fixed?
问题 Is it possible to configure Oracle 11g installation so that it has more than 18 characters length? Investigating possible cause of locally un-producible bug that might have been caused if customer configured rowid to have more than 18 characters. The table doesn't have an index. Using rowid to delete given records shortly after, but it's possible that other records are inserted in between. 回答1: If you're really looking at a logical ROWID (UROWID) or a ROWID from a non-Oracle database, sure.
