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.
