Note one caveat concerning SELECT/INTO and development style: The SELECT/INTO statement should not replace the use of joins or views. When the new table is created, it s a snapshot in time a second copy of the data. Databases containing multiple copies of old data sets are a sure sign of trouble. If you need to denormalize data for ad hoc analysis, or to pass to a user, then creating a view is likely a better alternative.
