DATABASEPROPERTYEX (Transact-SQL)

database

Is an expression that represents the name of the database for which to return the named property information. database is nvarchar(128).

property

Is an expression that represents the name of the database property to return. property is varchar(128), and can be one of the following values. The return type is sql_variant. The following table shows the base data type for each property value.

Note
If the database is not started, properties that the SQL Server retrieves by accessing the database directly instead of retrieving the value from metadata will return NULL. That is, if the database has AUTO_CLOSE set to ON, or the database is otherwise offline.

Property	Description	Value returned
Collation	Default collation name for the database.	Collation name NULL = Database is not started. Base data type: nvarchar(128)
ComparisonStyle	The Windows comparison style of the collation. ComparisonStyle is a bitmap that is calculated by using the following values. StyleValue Ignore case1 Ignore accent2 Ignore Kana65536 Ignore width131072 For example, the default of 196609 is the result of combining the Ignore case, Ignore Kana, and Ignore width options.	Returns the comparison style. Returns 0 for all binary collations. Base data type: int
IsAnsiNullDefault	Database follows ISO rules for allowing null values.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsAnsiNullsEnabled	All comparisons to a null evaluate to unknown.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsAnsiPaddingEnabled	Strings are padded to the same length before comparison or insert.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsAnsiWarningsEnabled	Error or warning messages are issued when standard error conditions occur.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsArithmeticAbortEnabled	Queries are ended when an overflow or divide-by-zero error occurs during query execution.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsAutoClose	Database shuts down cleanly and frees resources after the last user exits.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsAutoCreateStatistics	Query optimizer creates single-column statistics, as required, to improve query performance.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsAutoShrink	Database files are candidates for automatic periodic shrinking.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsAutoUpdateStatistics	Query optimizer updates existing statistics when they are used by a query and might be out-of-date.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsCloseCursorsOnCommitEnabled	Cursors that are open when a transaction is committed are closed.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsFulltextEnabled	Database is full-text enabled.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int Note The value of this property has no effect. User databases are always enabled for full-text search. This column will be removed in a future release of SQL Server. Do not use this column in new development work, and modify applications that currently use any of these columns as soon as possible.
IsInStandBy	Database is online as read-only, with restore log allowed.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsLocalCursorsDefault	Cursor declarations default to LOCAL.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsMergePublished	The tables of a database can be published for merge replication, if replication is installed.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsNullConcat	Null concatenation operand yields NULL.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsNumericRoundAbortEnabled	Errors are generated when loss of precision occurs in expressions.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsParameterizationForced	PARAMETERIZATION database SET option is FORCED.	1 = TRUE 0 = FALSE NULL = Input not valid
IsQuotedIdentifiersEnabled	Double quotation marks can be used on identifiers.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsPublished	The tables of the database can be published for snapshot or transactional replication, if replication is installed.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsRecursiveTriggersEnabled	Recursive firing of triggers is enabled.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsSubscribed	Database is subscribed to a publication.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsSyncWithBackup	The database is either a published database or a distribution database, and can be restored without disrupting transactional replication.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
IsTornPageDetectionEnabled	The SQL Server Database Engine detects incomplete I/O operations caused by power failures or other system outages.	1 = TRUE 0 = FALSE NULL = Input not valid Base data type: int
LCID	The Windows locale identifier (LCID) of the collation.	LCID value (in decimal format). Base data type: int For a list of LCID values (in hexadecimal format), see Collation Settings in Setup.
Recovery	Recovery model for the database.	FULL = Full recovery model BULK_LOGGED = Bulk logged model SIMPLE = Simple recovery model Base data type: nvarchar(128)
SQLSortOrder	SQL Server sort order ID supported in earlier versions of SQL Server.	0 = Database is using Windows collation >0 = SQL Server sort order ID NULL = Input not valid or database is not started Base data type: tinyint
Status	Database status.	ONLINE = Database is available for query. Note The ONLINE status may be returned while the database is being opened and is not yet recovered. OFFLINE = Database was explicitly taken offline. RESTORING = Database is being restored. RECOVERING = Database is recovering and not yet ready for queries. SUSPECT = Database did not recover. EMERGENCY = Database is in an emergency, read-only state. Access is restricted to sysadmin members Base data type: nvarchar(128)
Updateability	Indicates whether data can be modified.	READ_ONLY = Data can be read but not modified. READ_WRITE = Data can be read and modified. Base data type: nvarchar(128)
UserAccess	Indicates which users can access the database.	SINGLE_USER = Only one db_owner, dbcreator, or sysadmin user at a time RESTRICTED_USER = Only members of db_owner, dbcreator, and sysadmin roles MULTI_USER = All users Base data type: nvarchar(128)
Version	Internal version number of the SQL Server code with which the database was created. Identified for informational purposes only. Not supported. Future compatibility is not guaranteed.	Version number = Database is open. NULL = Database is not started. Base data type: int

sql_variant

Returns NULL on error or if a caller does not have permission to view the object.

In SQL Server, a user can only view the metadata of securables that the user owns or on which the user has been granted permission. This means that metadata-emitting, built-in functions such as OBJECT_ID may return NULL if the user does not have any permission on the object. For more information, see Metadata Visibility Configuration and Troubleshooting Metadata Visibility.

DATABASEPROPERTYEX returns only one property setting at a time. To display multiple property settings, use the sys.databases catalog view.

A. Retrieving the status of the AUTO_SHRINK database option

SELECT DATABASEPROPERTYEX('AdventureWorks2008R2', 'IsAutoShrink');

B. Retrieving the default collation for a database

SELECT DATABASEPROPERTYEX('AdventureWorks2008R2', 'Collation');
