Check If Auto Update Statistics Is Enabled With DATABASEPROPERTY

How do you check if auto update statistics is enabled on your database? It is pretty easy to check that, you can use the DATABASEPROPERTY function
Run the following line of code

SELECT DATABASEPROPERTY('pubs','IsAutoUpdateStatistics') AS IsAutoUpdateStatistics

If 1 is returned(true) it is enabled, if 0 is returned(false) then it is not enabled

Now to save me (and you) time I have pasted a code block below with all the properties, just change the database name from pubs to your database name and run the code


DECLARE @v VARCHAR(55)
SELECT @v = 'pubs'

SELECT
DATABASEPROPERTY(@v,'IsAnsiNullDefault') AS IsAnsiNullDefault,
DATABASEPROPERTY(@v,'IsAnsiNullsEnabled') AS IsAnsiNullsEnabled,
DATABASEPROPERTY(@v,'IsAnsiWarningsEnabled') AS IsAnsiWarningsEnabled,
DATABASEPROPERTY(@v,'IsAutoClose') AS IsAutoClose,
DATABASEPROPERTY(@v,'IsAutoCreateStatistics') AS IsAutoCreateStatistics,
DATABASEPROPERTY(@v,'IsAutoShrink') AS IsAutoShrink,
DATABASEPROPERTY(@v,'IsAutoUpdateStatistics') AS IsAutoUpdateStatistics,
DATABASEPROPERTY(@v,'IsBulkCopy') AS IsBulkCopy,
DATABASEPROPERTY(@v,'IsDboOnly') AS IsDboOnly,
DATABASEPROPERTY(@v,'IsDetached') AS IsDetached,
DATABASEPROPERTY(@v,'IsEmergencyMode') AS IsEmergencyMode,
DATABASEPROPERTY(@v,'IsInLoad') AS IsInLoad,
DATABASEPROPERTY(@v,'IsInRecovery') AS IsInRecovery,
DATABASEPROPERTY(@v,'IsAutoClose') AS IsAutoClose,
DATABASEPROPERTY(@v,'IsInStandBy') AS IsInStandBy,
DATABASEPROPERTY(@v,'IsLocalCursorsDefault') AS IsLocalCursorsDefault,
DATABASEPROPERTY(@v,'IsNotRecovered') AS IsNotRecovered,
DATABASEPROPERTY(@v,'IsNullConcat') AS IsNullConcat,
DATABASEPROPERTY(@v,'IsOffline') AS IsOffline,
DATABASEPROPERTY(@v,'IsQuotedIdentifiersEnabled') AS IsQuotedIdentifiersEnabled,
DATABASEPROPERTY(@v,'IsReadOnly') AS IsReadOnly,
DATABASEPROPERTY(@v,'IsRecursiveTriggersEnabled') AS IsRecursiveTriggersEnabled,
DATABASEPROPERTY(@v,'IsShutDown') AS IsShutDown,
DATABASEPROPERTY(@v,'IsSingleUser') AS IsSingleUser,
DATABASEPROPERTY(@v,'IsSuspect') AS IsSuspect,
DATABASEPROPERTY(@v,'IsTruncLog') AS IsTruncLog,
DATABASEPROPERTY(@v,'Version') AS Version
