Move SQL Server 2008 database files to a new folder location

Logical Name

• my_Data
• my_Log

Path:

• C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA
• C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA

FileName:

• my.MDF
• my_1.LDF

What would be the sql script to move these files to a new location: D:\DATA

Database is live so I would need to close existing connections.

You forgot to mention the name of your database (is it "my"?).

ALTER DATABASE my SET SINGLE_USER WITH ROLLBACK IMMEDIATE;

ALTER DATABASE my SET OFFLINE;

ALTER DATABASE my MODIFY FILE 
(
   Name = my_Data,
   Filename = 'D:\DATA\my.MDF'
);

ALTER DATABASE my MODIFY FILE 
(
   Name = my_Log, 
   Filename = 'D:\DATA\my_1.LDF'
);

Now here you must manually move the files from their current location to D:\Data\ (and remember to rename them manually if you changed them in the MODIFY FILE command) ... then you can bring the database back online:

ALTER DATABASE my SET ONLINE;

ALTER DATABASE my SET MULTI_USER;

This assumes that the SQL Server service account has sufficient privileges on the D:\Data\ folder. If not you will receive errors at the SET ONLINE command.

You can use Detach/Attach Option in SQL Server Management Studio.

To add the privileges needed to the files add and grant right to the following local user: SQLServerMSSQLUser$COMPUTERNAME$INSTANCENAME, where COMPUTERNAME and INSTANCENAME has to be replaced with name of computer and MSSQL instance respectively.
