Point to Tasks, point to Shrink, and then select Database.ĭisplays the name of the selected database.ĭisplays the total used and unused space for the selected database.ĭisplays the sum of free space in the log and data files of the selected database. In Object Explorer, connect to an instance of the SQL Server Database Engine, and then expand that instance.Įxpand Databases, and then right-click the database that you want to shrink. Use SQL Server Management Studio Shrink a database Requires membership in the sysadmin fixed server role or the db_owner fixed database role. Unless you have a specific requirement, do not set the AUTO_SHRINK database option to ON. This is another reason not to repeatedly shrink the database. In these cases, repeatedly shrinking the database is a wasted operation, and likely created the need for autogrowth events to reclaim the space, hindering performance.Ī shrink operation does not preserve the fragmentation state of indexes in the database, and generally increases fragmentation to a degree. If you shrink a database repeatedly and notice that the database size grows again, this indicates that the space that was shrunk is required for regular operations. Most databases require some free space to be available for regular day-to-day operations. For more information, see Display Data and Log Space Information for a DatabaseĬonsider the following information when you plan to shrink a database:Ī shrink operation is most effective after an operation that creates lots of unused space, such as a truncate table or a drop table operation. To view the current amount of free (unallocated) space in the database. Conversely, you cannot backup a database while a shrink operation on the database is in process. You cannot shrink a database while the database is being backed up. For example, if a database was originally created with a size of 10 MB and grew to 100 MB, the smallest size the database could be reduced to is 10 MB, even if all the data in the database has been deleted. The minimum size is the size specified when the database was originally created, or the last explicit size set by using a file-size-changing operation, such as DBCC SHRINKFILE. The database cannot be made smaller than the minimum size of the database. When enough free space is created at the end of the file, data pages at end of the file can be deallocated and returned to the file system. Shrinking data files recovers space by moving pages of data from the end of the file to unoccupied space closer to the front of the file.

This article describes how to shrink a database in SQL Server by using Object Explorer in SQL Server Management Studio or Transact-SQL. I would not think it is really necessary to shrink the database.Applies to: SQL Server (all supported versions) Azure SQL Database The files will automatically be increased in size. In your case you have 3Gb available in a 96Gb database, this is not that much.
There should be some free space because updates to the database will need some space to write this data to, using the default settings It is important to note that there should always be available space (unused) in the database so do not release all free space. In the maintance plan wizard select the rebuild index and shrink database tasks (first rebuild than shrink). You can also use a maintenance plan to reorganize the database and release unused space. ' and click OK. You can also shrink the log files.
In the dialog select the option 'Reorganize pages.
Just right click the database and select Tasks > Shrink > Files. You can shrink this using SQL Management Studio. Based on the table above I would say this space is in the data file of the database.
