*** When we restore DB we are always getting exclusive access error.
So I have written a Query to
set DB OFFLINE
RESTORE DB
Changing location of .MDF and .LDF files
ALTER DATABASE WSS_CONTENT_1545 SET OFFLINE WITH ROLLBACK IMMEDIATE
--ALTER DATABASE WSS_CONTENT_1545 SET ONLINE
USE[MASTER]
ALTER DATABASE WSS_CONTENT_1545
SET SINGLE_USER WITH ROLLBACK immediate
Restore database WSS_CONTENT_1545
from Disk = 'E:\Wss_Content_Bak.bak' with REPLACE,
move 'WSS_Content_1111' to 'E:\Intra\WSS_Content_1545.mdf',
move 'WSS_Content_1111_Log' to 'E:\Intra\WSS_Content_1545.ldf'
*** (WSS_Content_1111 is the OLD DATABASE NAME)
