    What's the best way of determining time of last server reboot from within a stored procedure?

    Thanks

    select

    dateadd(ss, -1*ms_ticks/1000, getdate()) "Last server reboot time"

    from

    sys.dm_os_sys_info

    Unfortunately we're on SQL Server 2000, not 2005.

    TempDb is rebuilt from the ground up on a reboot... this does the trick...

     SELECT CrDate AS LastRebootDate

       FROM Master.dbo.SysDatabases

      WHERE Name = 'TempDB'

    Thanks, but would this be the time of the last restart of SQL Server?  I'm looking for the Windows Server reboot.

    Ack... my fault... I'm so data-centric that I sometimes forget that SQL Server has to live on a Windows server (except for MSDE, Development Edition, etc).

    Nope, I don't know how to do this one without using some undocumented feature (not usually a good idea) like xp_GetFileDetails or xp_RegRead or maybe a trip through xp_CmdShell (with the DIR cmd) to check a file date that is created during Windows Server bootup.
