Finding latest full backup file name

We are instituting a procedure to restore the latest full backup (*.BAK
extension) of our production database to a training database in an automated
fashion. Is there a way to determine the pathname and filename of the latest
full backup of a database (from msdb perhaps). or do I need to use DOS Dir
command manipulation to get this information from file timestamps? I would
then use T-SQL to restore the filename over the existing training database.
Any ideas?

use msdb
go
select top 1
a.[name],
a.[database_name],
a.type,
a.backup_start_date,
a.backup_finish_date,
c.physical_device_name
from
dbo.backupset as a
inner join
dbo.backupmediaset as b
on a.media_set_id = b.media_set_id
inner join
dbo.backupmediafamily as c
on b.media_set_id = c.media_set_id
where
a.[database_name] = 'northwind'
and a.type = 'D'
order by
a.backup_finish_date desc

finding first record ... !?

I have a table as follows:

- user_id (key)
- user_email_address (text)
- user_request_date (text)
- user_sent_date (time/date)

An automated macro will run every 5 minutes and needs to run a SQL UPDATE
that:

- finds the FIRST (ONE ROW ONLY) (youngest) record where
- user_request_date is the most recent
- AND user_sent_date is NULL (i.e. blank)

- THEN UPDATES the user_sent_date for THAT record to NOW() (i.e. the
current system date/time)

For example:

- record 33 - request_date 01-JUL-03 14:55:03 - user_sent_date = NULL
- record 34 - request_date 01-JUL-03 15:03:46 - user_sent_date = NULL
- record 35 - request_date 01-JUL-03 16:08:08 - user_sent_date = NULL
- record 36 - request_date 01-JUL-03 16:57:31 - user_sent_date = NULL
- record 37 - request_date 01-JUL-03 17:11:41 - user_sent_date = NULL

SO - the above NEEDED SQL UPDATE would update ONLY row 33 (the FIRST ROW)

- update record 33 - with NOW() time and date
THEN record 34, then 35, then 36, then 37
ONE ROW at a time per each SQL UPDATE

Any ideas!?
Thanks!

richard @. rcbuchanan . comRichard,

Try something like

update Richard set
user_sent_date = getdate()
where user_id = (
select top 1 user_id from Richard R
where R.user_sent_date is null
order by user_request_date
)

Your narrative and your example don't agree on whether
you want the most recent (youngest), or least recent (oldest)
user_request_date, so you may need to add DESC to the
order by clause.
