First, recreate your Base. Table with the same name under a different schema, eg clone. The Fastest Way to Lose Fat This 4Minute, ScienceBacked Exercise. Base. Table. Using a separate schema will simplify the rename process later. Include the clustered index, if applicable. Remember that primary keys and unique constraints may be clustered, but not necessarily so.

Kaspersky Internet Security 2013 Crack Keygen - Full Version more. Defaults dont make much of difference, but were trying to keep. Mono-The-Movie-Trending-All-Day--728x470.jpg' alt='Fastest Way To Movies' title='Fastest Way To Movies' />Then, test your insert w 1. IDENTITY column in Base. Table. SET IDENTITYINSERT clone. Base. Table ON. INSERT clone. Base. Table WITH TABLOCK Col. Col. 2, Col. 3. SELECT TOP 1. Col. 1, Col. 2, Col. FROM dbo. Base. Table. SET IDENTITYINSERT clone. Base. Table OFF. Examine the results. If everything appears in order truncate the clone tablemake sure the database in in bulk logged or simple recovery modelperform the full insert. This will take a while, but not nearly as long as an update. Once it completes, check the data in the clone table to make sure it everything is correct. Then, recreate all non clustered primary keysunique constraintsindexes and foreign key constraints in that order. Recreate default and check constraints, if applicable. Recreate all triggers.

If you need to free up disk space, you may drop your original table at this time, though it may be prudent to keep it around a while longer. Needless to say, this is ideally an offline operation. If you have people modifying data while you perform this operation, you will have to perform a true up operation with the schema switch. I recommend creating a trigger on dbo. Base. Table to log all DML to a separate table. Enable this trigger before you start the insert. Then in the same transaction that you perform the schema transfer, use the log table to perform a true up. Test this first on a subset of the data Deltas are easy to screw up.
