How to Rename a SQL Server database?
One way to rename a SQL Server database is to use the sp_renamedb system stored procedure. This procedure can be executed from the query editor in SQL Server Management Studio.
To use sp_renamedb, you must be a member of the sysadmin fixed server role or have the ALTER DATABASE permission.
Here is the syntax for sp_renamedb:
sp_renamedb
[ @dbname = ] ‘database_name’ ,
[ @newname = ] ‘new_database_name’
For example, the following command would rename the database named “MyOldDatabase” to “MyNewDatabase”:
sp_renamedb
[ @dbname = ] ‘MyOldDatabase’ ,
[ @newname = ] ‘MyNewDatabase’
Another way to rename a SQL Server database is to detach it from the server, then attach it back with the new database name.
To detach a database, you must be a member of the sysadmin fixed server role or the db_owner fixed database role.
To attach a database, you must have CREATE DATABASE permissions.
Here are the steps to detach and attach a database:
1) In SQL Server Management Studio, connect to the SQL Server instance where the database you want to rename is located.
2) In the left pane, expand the server tree.
3) Right-click on the database you want to rename and select Tasks > Detach… from the menu.
4) In the Database Detach dialog window, check the Drop connections checkbox. This will ensure that all connections to the database are closed when it is detached.
5) Click OK to detach the database.
6) Copy the database files (.mdf and .ldf) to the new location. The new location can be on the same server or on a different server.
7) In SQL Server Management Studio, connect to the SQL Server instance where you want to attach the database.
8) In the left pane, expand the server tree.
9) Right-click on the Databases node and select Attach… from the menu.
10) In the Database Attach dialog window, click the Add… button.
11) In the Locate Database Files dialog window, browse to the new location of the database files and select the .mdf file.
12) Click OK to close the dialog window.
13) In the Database Attach dialog window, click the OK button to attach the database.
14) Enter the new name for the database in the Attach Database dialog window and click OK.
Now that the database has been renamed, you will need to update any applications that connect to it with the new name.

How to Rename a SQL Server database?
Why would you want to rename a SQL Server database?
There are a number of reasons why you might want to rename a SQL Server database. For example, you might want to:
– Reflect a change in the name of the underlying business (e.g., if your company is acquired by another).
– Clean up after a mistake (e.g., if you created the database with a typo in the name).
– Consolidate multiple databases into a single database (e.g., as part of a data warehousing project).
Whatever the reason, renaming a SQL Server database is a relatively simple process that can be completed in a few steps.
The process for renaming a SQL Server database
There are a few different ways that you can go about renaming a SQL Server database. One option is to use the sp_renamedb system stored procedure. You can also use the ALTER DATABASE statement, or you can detach and reattach the database.
The sp_renamedb system stored procedure is the easiest way to rename a SQL Server database. To use this procedure, you must be a member of the sysadmin fixed server role or have ALTER ANY DATABASE permissions. To rename a database, execute the following statement:
sp_renamedb ‘old_name’, ‘new_name’
The ALTER DATABASE statement can also be used to rename a database. This statement can be executed by members of the sysadmin or dbcreator fixed server roles, or by users with ALTER ANY DATABASE permissions. To rename a database using the ALTER DATABASE statement, use the following syntax:
ALTER DATABASE old_name MODIFY NAME = new_name
If you need to rename a SQL Server database, but you don’t have permissions to modify the database directly, you can detach the database, rename the files, and then reattach the database. To detach a database, you can use the sp_detach_db system stored procedure. This procedure can be executed by members of the sysadmin or dbcreator fixed server roles, or by users with ALTER ANY DATABASE permissions. The syntax for the sp_detach_db stored procedure is as follows:
sp_detach_db ‘database_name’
Once the database has been detached, you can rename the database files. The default location for database files is the C:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\DATA directory.
After you have renamed the database files, you can reattach the database by using the sp_attach_db system stored procedure. This procedure can be executed by members of the sysadmin or dbcreator fixed server roles, or by users with ALTER ANY DATABASE permissions. The syntax for the sp_attach_db stored procedure is as follows:
sp_attach_db ‘database_name’, ‘data_file_name’
where data_file_name is the full path of the renamed data file.
Things to consider before renaming a SQL Server database
When renaming a SQL Server database, there are a few things to consider:
1. Ensure that all users and applications that connect to the database are using the new name.
2. Make sure that any automated scripts or processes that reference the database are updated to use the new name.
3. Update any external references to the database, such as in backup or monitoring scripts.
4. Take a final backup of the database before renaming it. This will ensure that you have a copy of the database under the old name in case you need to roll back the changes.
Troubleshooting tips for renaming a SQL Server database
If you’re having trouble renaming a SQL Server database, here are some troubleshooting tips that may help.
First, check the database name to ensure it is valid according to SQL Server rules. It must be alphanumeric and cannot exceed 128 characters.
If the database name is valid, check to see if there are any active connections to the database. If so, you will need to close those connections before proceeding.
Next, check the permissions to see if you have the necessary permissions to rename the database. You will need to be a member of the sysadmin fixed server role or have the ALTER ANY DATABASE permission.
If all of the above checks out, then you should be able to successfully rename the database.
