I have rebuilt some indexes which were highly fragmented. After the index rebuild I am seeing my database space used reduced by almost 50% (from 77gb to 33 gb)
Is that normal behavior? I dont have auto shrink turned on - did I lose data?
Note: space used decreased in my database file; the actual physical size of my database file is unchanged.
Command used to calculate the space used:
SELECT sum(CAST(FILEPROPERTY(name, ''SpaceUsed'') AS INT))/128.0 as Space_Used_MB
Microsoft SQL Server 2014 (SP2-CU11) (KB4077063) - 12.0.5579.0 (X64)
Rebuild of indexes performed using Ola Hallengren's script. Parameters used:
Databases = 'USER_DATABASES', FragmentationMedium='INDEX_REORGANIZE,INDEX_REBUILD_ONLINE,INDEX_REBUILD_OFFLINE ', FragmentationHigh = 'INDEX_REBUILD_ONLINE,INDEX_REBUILD_OFFLINE', FragmentationLevel1 = 5, FragmentationLevel2 = 30, FillFactor=80, UpdateStatistics = 'ALL', OnlyModifiedStatistics = 'Y', LogToTable = 'Y'" -b
