SSIS Talk

There are many, many resources out on the ‘Net regarding SSIS and the Lookup component and what each of its cache modes are and how to implement them in your own package. This is going to be a technical post, for those of you interested in what each cache mode does behind the scenes.

I know, this isn’t “breaking” news or anything, but what is new is the white paper detailing how Microsoft was able to achieve this record breaking speed using SSIS. Check it out below as its a very interesting read, and it may help generate some new ideas for your implementations.

From the SSIS development team, Matt Masson has posted a few blog posts on how to use the SSIS API. The posts use references to the 2008 version of SSIS, but to modify them for 2005 requires a simple change in most cases – Upgrading custom SSIS 2005 components to 2008.

You can find the blog posts here: http://blogs.msdn.com/mattm/archive/2008/12/30/samples-for-creating-ssis-packages-programmatically.aspx

Also, there is a post on using a new API framework for SSIS 2008, titled EzAPI: http://blogs.msdn.com/mattm/archive/2008/12/30/ezapi-alternative-package-creation-api.aspx

I haven’t looked into the EzAPI yet, but it certainly sounds interesting.

Let me know what you think about the new posts and if you’d like to see any thing else from the dev team and I’ll pass it along.

Last night a user posted to the SSIS Forum a situation where he needed to be able to dynamically substring one field based on the substring rules contained in a table. So I put together a package that does just this. Before we go there though, I just want to mention that there are many ways, progmatically of course, to tackle this problem. The example below strictly follows my interpretations of Bill’s challenge. There is a better way by using the split() function, but never-the-less here’s the example using substring().
