Subj:   Managing deleted records
 
From:   Anomy Anom

Hello,

Our data warehouse marks deleted records and then removes them from the tables. Ideally, we would like the ability to make the delete process seamless from the users by using a view that they would access that only contains active records. I've used this method before with another DBMS that supported bit map index on a active/not-active column. I tried implementing in Teradata, but without a secondary index, table scans were occurring. Here's my dilemma: I don't want to add an index to the TD tables because that would prevent using mload and we don't have enough time to drop/re-create an index. Is there a way to achieve this? Any other ideas?

Thanks in advance for any ideas and suggestions.
