Applies to: SQL Server

Sets certain database behaviors to be compatible with the specified version of SQL Server.

Important

This feature will be removed in a future version of SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Use ALTER DATABASE (Transact-SQL) compatibility level instead.

Transact-SQL syntax conventions

Syntax

sp_dbcmptlevel
    [ [ @dbname = ] N'dbname' ]
    [ , [ @new_cmptlevel = ] new_cmptlevel OUTPUT ]
[ ; ]

Arguments

[ @dbname = ] N'dbname'

The name of the database for which the compatibility level is to be changed. Database names must conform to the rules for identifiers. @dbname is sysname, with a default of NULL.

[ @new_cmptlevel = ] new_cmptlevel OUTPUT

The version of SQL Server with which the database is to be made compatible. @new_cmptlevel is an OUTPUT parameter of type tinyint, and must be one of the following values:

90 = SQL Server 2005 (9.x)
100 = SQL Server 2008 (10.0.x)
110 = SQL Server 2012 (11.x)
120 = SQL Server 2014 (12.x)
130 = SQL Server 2016 (13.x)
140 = SQL Server 2017 (14.x)
150 = SQL Server 2019 (15.x)
160 = SQL Server 2022 (16.x)

Return code values

0 (success) or 1 (failure).

Result set

If no parameters are specified or if the @dbname parameter isn't specified, sp_dbcmptlevel returns an error.

If @dbname is specified without @new_cmptlevel, the Database Engine returns a message displaying the current compatibility level of the specified database.

Remarks

For a description of compatibilities levels, see ALTER DATABASE (Transact-SQL) compatibility level.

Permissions

Only the database owner, members of the sysadmin fixed server role, and the db_owner fixed database role (if you're changing the current database) can execute this procedure.
