Hi there
Is there functionality in SQL 2005 to update only new records, e.g. only records from yesterday. I've seen functionality for dimension tables to only get new records but nothing for fact tables.
Thanks
Not altogether sure I understand the requirement but I'll try.
Once you have your records that need to be updated (by whatever means you use to do that), have a LOOKUP component that checks the fact table to see which of those rows were loaded yesterday (or whenever).

Hi Jamie
Thanks for the reply, I want to do an iterative update of my datawarehouse add new records only rather than deleting the table and reimporting the entire table. I have read about variables etc and I thought there might be a way to query the data warehose to check the most recent record then use that to update my sql query which brings in the data. By the way I'm using ODBC connection for this.
Cheers,
Kiwi
