    a nifty little script, I installed the SP on a couple of boxes and straightaway found some little databases no-one cared about enough to monitor that were on 'full recovery' but had no tran-log backups setup.

    Hi,

    that's exactly why i wrote it, people often forget to remove full recovery mode when they copy from a production environment, so it has caused me issues in the past.

    Thanks

    /*

    Why are you using temp table and using subquery? A subquery is not as efficient as a join or a derived table or an exists. The latter being the most optimal. This would have been far more efficient in typing and execution.

    You have allocated a data type varchar(50) for the database name when this should have been syname or nvarchar(128) as per the system tables that you are refering to. This would fail for database with a name > 50 characters

    I would like to have had the date of the last backup if I'm checking.

    The LEFT JOIN for the derived table in the example from stuart.adair should be on b.database_name (not b.DateLogLastBackedUp):

    ) b ON a.[name] = b.database_name
