Usually you would like to know last time a database was restored. This is very handy script to show you the details.
WITH LastRestores AS
DatabaseName = [d].[name] ,
RowNum = ROW_NUMBER() OVER (PARTITION BY d.Name ORDER BY r.[restore_date] DESC)
FROM master.sys.databases d
LEFT OUTER JOIN msdb.dbo.[restorehistory] r ON r.[destination_database_name] = d.Name
FROM [LastRestores] WHERE [RowNum] = 1
You can simply get the details from dbo.restorehistory from MSDB databases. However, the above script will provide more details.
