Changes the name of a user database.
sp_renamedb dbname, newname
is the original name of the database.
is the new name of the database. Database names must conform to the rules for identifiers and must be unique.
Renames the accounting database to financial:
sp_renamedb accounting, financial
Renames the database named work, which is a Transact-SQL reserved word, to workdb. This example shows how sp_dboption is used to place the work database in single-user mode before renaming it and restore it to multi-user mode afterward:
sp_dboption work, single, true go use work go checkpoint go sp_renamedb work, workdb go use master go sp_dboption workdb, single, false go use workdb go checkpoint go
sp_renamedb changes the name of a database. You cannot rename system databases or databases with external referential integrity constraints.
The System Administrator must place a database in single-user mode with sp_dboption before renaming it and must restore it to multi-user mode afterward.
sp_renamedb fails if any table in the database references, or is referenced by, a table in another database. Use the following query to determine which tables and external databases have foreign key constraints on primary key tables in the current database:
select object_name(tableid), db_name(frgndbid) from sysreferences where frgndbid is not null
Use the following query to determine which tables and external databases have primary key constraints for foreign key tables in the current database:
select object_name(reftabid), db_name(pmrydbid) from sysreferences where pmrydbid is not null
Use alter table to drop the cross-database constraints in these tables. Then, rerun sp_renamedb.
When you change a database name:
Drop all stored procedures, triggers, and views that include the database name
Change the source text of the dropped objects to reflect the new database name
Re-create the dropped objects
Change all applications and SQL source scripts that reference the database, either in a use database_name command or as part of a fully qualified identifier (in the form dbname.[owner].objectname)
If you use scripts to run dbcc commands or dump database and dump transaction commands on your databases, be sure to update those scripts.
WARNING! Procedures, triggers, and views that depend on a database whose name has been changed work until they are re-created. Change the definitions of any dependent objects when you execute sp_renamedb. Find dependent objects with sp_depends.
Only a System Administrator can execute sp_renamedb.
