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.
