Shrink database after removing extra data We have a need to fit a database in 4GB in order to use SQL Server Express Edition. I started from a 7GB database, and found a lot of unneeded records, and deleted them. After shrinking, the database size is 4.6GB, and 748 MB is free (according to database properties).

However, when I execute exec sp_spaceused, I have interesting results:

DatabaseName    Database_size   unallocation space
xxxxxx          4726.50 MB      765.42 MB


Reserved        Data          index_size      unused
3899472 KB      1608776 KB    1448400 KB      842296 KB


Any ideas, how can I release at least some of this unused space?
Also I know table, which occupied it.

Update: is it worth to trying to rebuild table indexes?

ALTER INDEX ALL ON Production.Product REBUILD
After index recreation, using this command:

ALTER INDEX ALL ON Production.Product REBUILD


and than I run SHRINK command again - end up with 2.5G database.
