Scenario:
Let's say that you are working as SQL Server DBA and you tons of backups files sitting in one of the folder, you need to restore all those backups files to newly created DEV , QA or UAT server. If you will start restoring one after one manually, it will take you forever. You are looking for some scripts those can restore these full backups files to newly created server.
You will be able to use this type of script to refresh databases on regular basis such as monthly or on demand from Production to lower environments.
I have tested this script on SQL Server 2016. You might get some error in case you are using old versions or latest versions as sometime microsoft change the number of columns returned by RESTORE FILELISTONLY.
Check the columns list and update the definition of temp tables according to your version, rest of the script will be same.
I did write same type of script before but I was considering the databases will have only mdf and ldf,
Check here. The below script can handle database with NDF as well and
overwrite existing DB if exists.--Provide the folder path where backups are present
DECLARE @BackupFolder VARCHAR(128)
