sp_certify_removable (Transact-SQL)

  • Artikkeli

Applies to: SQL Server

Verifies that a database is correctly configured for distribution on removable media and reports any problems to the user.

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 CREATE DATABASE instead.

Transact-SQL syntax conventions

Syntax

sp_certify_removable
    [ @dbname = ] N'dbname'
    [ , [ @autofix = ] N'autofix' ]
[ ; ]

Arguments

[ @dbname = ] N'dbname'

Specifies the database to be verified. @dbname is sysname.

[ @autofix = ] N'autofix'

Gives ownership of the database and all database objects to the system administrator, and drops any user-created database users and nondefault permissions. @autofix is nvarchar(4), with a default of NULL.

Return code values

0 (success) or 1 (failure).

Remarks

If the database is correctly configured, sp_certify_removable performs the following steps:

  • Sets the database offline so the files can be copied.
  • Updates statistics on all tables and reports any ownership or user problems
  • Marks the data filegroups as read-only so these files can be copied to read-only media.

The system administrator must be the owner of the database and all database objects. The system administrator is a known user that exists on all servers running SQL Server, and can be expected to exist when the database is later distributed and installed.

If you run sp_certify_removable without the AUTO value and it returns information about any of the following conditions:

  • The system administrator isn't the database owner.
  • Any user-created users exist.
  • The system administrator doesn't own all objects in the database.
  • Nondefault permissions have been granted.

You can correct those conditions in the following ways:

  • Use SQL Server tools and procedures, and then run sp_certify_removable again.
  • Run sp_certify_removable with the AUTO value.

This stored procedure only checks for users and user permissions. You can add groups to the database and to grant permissions to those groups. For more information, see GRANT.

Permissions

Execute permissions are restricted to members of the sysadmin fixed server role.

Examples

The following example certifies that the inventory database is ready to be removed.

EXEC sp_certify_removable inventory, AUTO;
