Fully automated SQL Server Restore

Question

I\'m not very fluent with SQL Server commands.

I need a script to restore a database from a .bak file and move the logical_data and logical_log files to a specific p

Answer 1

Yet another modification/implementations. Here's my 2 cents. I have modified Mevdiven's script above, so that it will restore the file to the current database data directory. I have a problem in that I do not want to use the location defined in the back up file.

I grab the data directory used by the first master file

SELECT top(1) @v_strRestorePath =  physical_name FROM sys.master_files

And use that as my destination data path.

I also found that the ##FILE_LIST table was hanging around, so I drop it near the end.

The extra --' are just so the SQL looks nice on Stack overflow
