    Nice idea. But I'm getting error while trying to create the proc.

    Msg 102, Level 15, State 1, Procedure USP_BackupDatabasesOnPr01, Line 32

    Incorrect syntax near '?'.

    Seems that there's something on the previous line SQL doesn't like.

    Hi Ken,

    Sorry about that.

    please try below:

    USE [master]

    GO

    /****** Object: StoredProcedure [dbo].[USP_BackupDatabasesOnPr01] Script Date: 02/14/2011 09:04:17 ******/

    SET ANSI_NULLS ON

    GO

    SET QUOTED_IDENTIFIER ON

    GO

    alter Proc [dbo].[USP_BackupDatabasesOnPr01] -- exec USP_BackupDatabasesOnPr01 'V:\Data\January Backups\'

    @path nvarchar(4000)

    as

    /*

    Author: Shanu Hoosen

    Date: Created:31/01/2011

    Execute as: Exec USP_BackupDatabasesOnPr01 'drive:\FolderPath'

    */

    declare @sql nvarchar(4000)

    declare @i nvarchar(3)

    declare @mx int

    declare @DBName nvarchar(500)

    --declare @path nvarchar(4000)

    --set @path = 'V:\Data\January Backups\'

    select ROW_NUMBER() OVER(ORDER BY name)id,name

    into #d

    from sysdatabases

    where sid <> 0x01

    set @i = (select min(id) from #d)

    set @mx = (select max(id)+1 from #d)

    while @i <> @mx

    begin

    set @DBName=(select '['+name+']' from #d where id = @i)

    set @sql = 'BEGIN TRY

    BACKUP DATABASE '+ @DBName +'

    TO DISK = N'''+@path+ replace(replace (@DBName, '[',''),']','') +'-'+ replace(cast(getdate() as nvarchar(500)),':','')+'.bak'''+

    ' WITH NOFORMAT, NOINIT,

    NAME = N'''+@DBName +'-Full Database Backup'''+','

    +'SKIP, NOREWIND, NOUNLOAD, STATS = 10

    END TRY

    BEGIN CATCH

    SELECT

    ERROR_NUMBER() AS ErrorNumber,

    ERROR_SEVERITY() AS ErrorSeverity,

    ERROR_STATE() AS ErrorState,

    ERROR_PROCEDURE() AS ErrorProcedure,

    ERROR_LINE() AS ErrorLine,

    END CATCH'

    --print(@sql)

    exec(@sql)

    set @i =@i+1

    end

    drop table #d

    Ok, I don't know what you did there but this version compiles and executes (I took out the call to executing the actual backups in favor of printing out the string).

    Thanks,

    This was the original version that I created.

    The only difference is, should it fail eg space limitations, it will not give the effected DB.

    By adding '@DBName' + errormessage() on the last line will overcome the shortfall.

    But as long as it works:)

    Just ran this on a WIN2K Sql SERVER providing the UNC path to the backup shared network drivespace which I verified I have access to and received this error...

    Server: Msg 195, Level 15, State 10, Procedure USP_BackupDatabasesOnPr01, Line 18

    'ROW_NUMBER' is not a recognized function name.

    Server: Msg 170, Level 15, State 1, Procedure USP_BackupDatabasesOnPr01, Line 32

    Line 32: Incorrect syntax near '?'.

    Any thoughts?

    Thanks..

    Row_Number() was introduced in SQL 2005. Are you on that or is your SQL Server 2000?

    I'm on a SQL 2000 server....

    An alternate to the row_number() function would be to create a table with an identity (1,1) column.

    All we are trying to acheive is a sequential increase by 1, which the loop can pick up. During the insert ignore the Identity column.

    Let me know if this helps.
