All Database full backup

/*
This script is to loop through all non-temp databases and create a full backup in the
designated directory. It also verifies that the backup when complete. Each database
will be place in their own directory.

The
master.dbo.xp_create_subdir only works with SQL Server 2005. It can be removed for 2000 if the directory already exists.

Interesting Blog Post

As a person who frequently has to review and clean up others TSQL I always spend a lot of time formatting to review. Additionally, I can have to format it to the clients TSQL standard. This is a script for colour formatting the output to a file that will be easier to read and distribute. It does require command execution from the SQL Server instance and this is something that I do not give to many of the servers I manage so I can't quickly test it hear.

I am putting hear so I can try it as I think it could solve several issues:

Guarantee a temp table is dropped

/*
The pupose of this post is to demonstrate the correct method of creating a temp table.
The key is to make sure that the drop statements are wrapped with an if statement and
placed both prior to table creation and after its use.
This is another argument for using temp table variables and common table expressions
*/

IF
EXISTS(SELECT name FROM tempdb.dbo.sysobjects WHERE type = N'U' AND name like N'#tModelItems%') DROP TABLE #tModelItems;

CREATE TABLE #tModelItems(
ItemNbr varchar (15),
QuantityPer decimal(11,3),
GroupCode char(1),
GroupCodeDesc varchar(50),
DrawingInd char(10),
);

--Use table

IF EXISTS(SELECT name FROM tempdb.dbo.sysobjects WHERE type = N'U' AND name like N'#tModelItems%') DROP TABLE #tModelItems;

Raising errors in the history

/*
I have been looking into raising customer errors in a large collection of file copy routines I am creating to provide better logging for a collection of PDFs we use for various websites. This is a start of what I am looking for and will be added to as I find new features.

The error will be posted in the SSIS history so it will be easier to find when doing the morning audit.
