Database Properties (Options Page)
Applies to: SQL Server (all supported versions)
Use this page to view or modify options for the selected database. For more information about the options available on this page, see ALTER DATABASE SET Options (Transact-SQL) and ALTER DATABASE SCOPED CONFIGURATION (Transact-SQL).
Specify the collation of the database by selecting from the list. For more information, see Set or Change the Database Collation.
Specify one of the following models for recovering the database: Full, Bulk-Logged, or Simple. For more information about recovery models, see Recovery Models (SQL Server).
Specify the latest version of SQL Server that the database supports. For possible values, see ALTER DATABASE (Transact-SQL) Compatibility Level. When a SQL Server database is upgraded, the compatibility level for that database is retained if possible, or changed to the minimum level supported for the new SQL Server.
Specify none or partial to designate if this is a contained database. For more information about contained databases, see Contained Databases. The server property Enable Contained Databases must be set to TRUE before a database can be configured as contained.
Enabling partially contained databases delegates control over access to the instance of SQL Server to the owners of the database. For more information, see Security Best Practices with Contained Databases.
Specify whether the database shuts down cleanly and frees resources after the last user exits. Possible values are True and False. When True, the database is shut down cleanly and its resources are freed after the last user logs off.
Auto Create Incremental Statistics
Specify whether to use the incremental option when per partition statistics are created. For information about incremental statistics, see CREATE STATISTICS (Transact-SQL).
Auto Create Statistics
Specify whether the database automatically creates missing optimization statistics. Possible values are True and False. When True, any missing statistics needed by a query for optimization are automatically built during optimization. For more information, see AUTO_CREATE_STATISTICS.
Specify whether the database files are available for periodic shrinking. Possible values are True and False. For more information, see Shrink a Database.
Auto Update Statistics
Specify whether the database automatically updates out-of-date optimization statistics. Possible values are True and False. When True, any out-of-date statistics needed by a query for optimization are automatically built during optimization. For more information, see AUTO_UPDATE_STATISTICS.
Auto Update Statistics Asynchronously
When True, queries that initiate an automatic update of out-of-date statistics do not wait for the statistics to be updated before compiling. Subsequent queries use the updated statistics when they are available.
When False, queries that initiate an automatic update of out-of-date statistics, wait until the updated statistics can be used in the query optimization plan.
Setting this option to True has no effect unless Auto Update Statistics is also set to True.
When connected to Azure SQL Database, this section has settings to control the Service Level Objective (SLO). The default SLO for a new database is Standard S2.
Current Service Level Objective The specific SLO to use. Valid values are constrained by the selected edition. If your desired SLO value is not in the list, you can type the value.
Edition The Azure SQL Database edition to use, such as Basic or Premium. If the edition value you need is not in the list, you can type the value, which must match the value used in Azure REST APIs.
Max Size The maximum size of the database. If the desired size value is not in the list, you can type the value. Leave blank for the default size of the given edition and SLO.
In a contained database, some settings usually configured at the server level can be configured at the database level.
Default Fulltext Language LCID
Specifies a default language for full-text indexed columns. Linguistic analysis of full-text indexed data is dependent on the language of the data. The default value of this option is the language of the server. For the language that corresponds to the displayed setting, see sys.fulltext_languages (Transact-SQL).
The default language for all new contained database users, unless otherwise specified.
Nested Triggers Enabled
Allows triggers to fire other triggers. Triggers can be nested to a maximum of 32 levels. For more information, see the "Nested Triggers" section in CREATE TRIGGER (Transact-SQL).
Transform Noise Words
Suppress an error message if noise words, that is stopwords, cause a Boolean operation on a full-text query to return zero rows. For more information, see transform noise words Server Configuration Option.
Two Digit Year Cutoff
Indicates the highest year number that can be entered as a two-digit year. The year listed and the previous 99 years can be entered as a two-digit year. All other years must be entered as a four-digit year.
For example, the default setting of 2049 indicates that a date entered as '3/14/49' will be interpreted as March 14, 2049, and a date entered as '3/14/50' will be interpreted as March 14, 1950. For more information, see Configure the two digit year cutoff Server Configuration Option.
Close Cursor on Commit Enabled
Specify whether cursors close after the transaction opening the cursor has committed. Possible values are True and False. When True, any cursors that are open when a transaction is committed or rolled back are closed. When False, such cursors remain open when a transaction is committed. When False, rolling back a transaction closes any cursors except those defined as INSENSITIVE or STATIC. For more information, see SET CURSOR_CLOSE_ON_COMMIT (Transact-SQL).
Specify default cursor behavior. When True, cursor declarations default to LOCAL. When False, Transact-SQL cursors default to GLOBAL.
Database Scoped Configurations
In SQL Server 2016 and in Azure SQL Database, there are a number of configuration properties that can be scoped to the database level. For more information for all of these settings, see ALTER DATABASE SCOPED CONFIGURATION (Transact-SQL).
Legacy Cardinality Estimation
Specify the query optimizer cardinality estimation model for the primary independent of the compatibility level of the database. This is equivalent to Trace Flag 9481.
Legacy Cardinality Estimation for Secondary
Specify the query optimizer cardinality estimation model for secondaries, if any, independent of the compatibility level of the database. This is equivalent to Trace Flag 9481.
Specify the default MAXDOP setting for the primary that should be used for statements.
Max DOP for Secondary
Specify the default MAXDOP setting for secondaries, if any, that should be used for statements.
Enables or disables parameter sniffing on the primary. This is equivalent to Trace Flag 4136.
Parameter Sniffing for Secondary
Enables or disables parameter sniffing on secondaries, if any. This is equivalent to Trace Flag 4136.
Query Optimizer Fixes
Enables or disables query optimization hotfixes on the primary regardless of the compatibility level of the database. This is equivalent to Trace Flag 4199. For details, see QUERY_OPTIMIZER_HOTFIXES.
Query Optimizer Fixes for Secondary
Enables or disables query optimization hotfixes on secondaries, if any, regardless of the compatibility level of the database. This is equivalent to Trace Flag 4199. For details, see QUERY_OPTIMIZER_HOTFIXES.
FILESTREAM Directory Name
Specify the directory name for the FILESTREAM data associated with the selected database.
FILESTREAM Non-transacted Access
Specify one of the following options for non-transactional access through the file system to FILESTREAM data stored in FileTables: OFF, READ_ONLY, or FULL. If FILESTREAM is not enabled on the server, this value is set to OFF and is disabled. For more information, see FileTables (SQL Server).
Allow Snapshot Isolation
Enables this feature.
ANSI NULL Default
Allow null values for all user-defined data types or columns that are not explicitly defined as NOT NULL during a CREATE TABLE or ALTER TABLE statement (the default state). For more information, see SET ANSI_NULL_DFLT_ON (Transact-SQL) and SET ANSI_NULL_DFLT_OFF (Transact-SQL).
ANSI NULLS Enabled
Specify the behavior of the Equals (
=) and Not Equal To (
<>) comparison operators when used with null values. Possible values are True (on) and False (off). When True, all comparisons to a null value evaluate to UNKNOWN. When False, comparisons of non-UNICODE values to a null value evaluate to True if both values are NULL. For more information, see SET ANSI_NULLS (Transact-SQL).
ANSI Padding Enabled
Specify whether ANSI padding is on or off. Permissible values are True (on) and False (off). For more information, see SET ANSI_PADDING (Transact-SQL).
ANSI Warnings Enabled
Specify ISO standard behavior for several error conditions. When True, a warning message is generated if null values appear in aggregate functions (such as SUM, AVG, MAX, MIN, STDEV, STDEVP, VAR, VARP, or COUNT). When False, no warning is issued. For more information, see SET ANSI_WARNINGS (Transact-SQL).
Arithmetic Abort Enabled
Specify whether the database option for arithmetic abort is enabled or not. Possible values are True and False. When True, an overflow or divide-by-zero error causes the query or batch to terminate. If the error occurs in a transaction, the transaction is rolled back. When False, a warning message is displayed, but the query, batch, or transaction continues as if no error occurred. For more information, see SET ARITHABORT (Transact-SQL).
Concatenate Null Yields Null
Specify the behavior when null values are concatenated. When the property value is True, string + NULL returns NULL. When False, the result is string. For more information, see SET CONCAT_NULL_YIELDS_NULL (Transact-SQL).
Cross-database Ownership Chaining Enabled
This read-only value indicates if cross-database ownership chaining has been enabled. When True, the database can be the source or target of a cross-database ownership chain. Use the ALTER DATABASE statement to set this property.
Date Correlation Optimization Enabled
When True, SQL Server maintains correlation statistics between any two tables in the database that are linked by a FOREIGN KEY constraint and have datetime columns.
When False, correlation statistics are not maintained.
Enables this feature. For more information, see Control Transaction Durability.
Is Read Committed Snapshot On
Enables this feature.
Specify how the database handles rounding errors. Possible values are True and False. When True, an error is generated when loss of precision occurs in an expression. When False, losses of precision do not generate error messages, and the result is rounded to the precision of the column or variable storing the result. For more information, see SET NUMERIC_ROUNDABORT (Transact-SQL).
When SIMPLE, queries are parameterized based on the default behavior of the database. When FORCED, SQL Server parameterizes all queries in the database.
Quoted Identifiers Enabled
Specifies a database default for the whether SQL Server double quote
" is used to specify delimited identifiers (true) or varchar literals (false). Possible values are true and false. For more information, see SET QUOTED_IDENTIFIER. This database default setting can be overridden by a session's setting, and many client drivers SET QUOTED_IDENTIFIER ON at connection time.
Recursive Triggers Enabled
Specify whether triggers can be fired by other triggers. Possible values are True and False. When set to True, this enables recursive firing of triggers. When set to False, only direct recursion is prevented. To disable indirect recursion, set the nested triggers server option to 0 using sp_configure. For more information, see Create Nested Triggers.
When displaying True, this read-only option indicates that SQL Server allows access to resources outside the database under an impersonation context established within the database. Impersonation contexts can be established within the database using the EXECUTE AS user statement or the EXECUTE AS clause on database modules.
To have access, the owner of the database also needs to have the AUTHENTICATE SERVER permission at the server level.
This property also allows the creation and execution of unsafe and external access assemblies within the database. In addition to setting this property to True, the owner of the database must have the EXTERNAL ACCESS ASSEMBLY or UNSAFE ASSEMBLY permission at the server level.
By default, all user databases and all system databases (with the exception of MSDB) have this property set to False. The value cannot be changed for the model and tempdb databases.
TRUSTWORTHY is set to False whenever a database is attached to the server.
The recommended approach for accessing resources outside the database under an impersonation context is to use certificates and signatures as apposed to the Trustworthy option.
To set this property, use the ALTER DATABASE statement.
VarDecimal Storage Format Enabled
This option is read-only starting with SQL Server 2008. When True, this database is enabled for the vardecimal storage format. Vardecimal storage format cannot be disabled while any tables in the database are using it. In SQL Server 2008 and later versions, all databases are enabled for the vardecimal storage format. This option uses sp_db_vardecimal_storage_format.
Specify the option used to discover and report incomplete I/O transactions caused by disk I/O errors. Possible values are None, TornPageDetection, and Checksum. For more information, see Manage the suspect_pages Table (SQL Server).
Target Recovery Time (Seconds)
Specifies the maximum bound on the time, expressed in seconds, to recover the specified database in the event of a crash. For more information, see Database Checkpoints (SQL Server).
Enables or disables Service Broker.
Honor Broker Priority
Read-only Service Broker property.
Serice Broker Identifier
Database Read Only
Specify whether the database is read-only. Possible values are True and False. When True, users can only read data in the database. Users cannot modify the data or database objects; however, the database itself can be deleted using the
DROP DATABASE statement. The database cannot be in use when a new value for the Database Read Only option is specified. The master database is the exception, and only the system administrator can use master while the option is being set.
View the current state of the database. It is not editable. For more information about Database State, see Database States.
When True, this database is enabled for database encryption. A Database Encryption Key is required for encryption. For more information, see Transparent Data Encryption (TDE).
Specify which users may access the database. Possible values are:
The normal state for a production database, allows multiple users to access the database at once.
Used for maintenance actions, only one user is allowed to access the database at once.
Only members of the db_owner, dbcreator, or sysadmin roles can use the database.
