can anyone pls help how to set the db offline. currently  i  stopped the sql server services from services.msc and started the  sql server agent.
should i stop both services for moving from one drive to another?
note: I tried teh below solution but this didint work:
ALTER DATABASE <DBName> SET OFFLINE WITH ROLLBACK IMMEDIATE
Update:
now am getting the message :
Msg 15010, Level 16, State 1, Procedure sp_detach_db, Line 40
The database 'CMP_143' does not exist. Supply a valid database name. To see available databases, use sys.databases.

Answer 1

First you should have checked the database mdf/ldf name and location by using the command
Use CMP_143
Go
Sp_helpfile
Looks like your database CMP_143 was successfully detached but mdf/ldf location or name was different that is why it did not get copied to target location.
Database is already detached that’s why db offline failed
Msg 15010, Level 16, State 1, Procedure sp_detach_db, Line 40
The database 'CMP_143' does not exist. Supply a valid database name. To see available databases, use sys.databases.
EXEC @RC = sp_attach_db @DBName, @DESTData, @DESTLog
Attached step is failing as there is no mdf file
Msg 5120, Level 16, State 101, Line 1
Unable to open the physical file "D:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA\CMP_143.mdf". Operating system error 2: "2(The system cannot find the file specified.)"
Solution:
Search for the physical files(mdf/ldf) in the OS and copy to target location and the re-run sp_attach_db with right location and name of mdf/ldf.
