Change Data Capture with SSIS

In this presentation, Brian Knight shows you how to use canned SSIS components to detect data changes in a source table and only load new or conditionally update changed records. He shows you two methods: one using the OLE DB command and another using a set based operation and demostrates you the performance differences between the two.

Thanks Brian for this wonderful explanation. However, this works for a specific table.. what if there are many tables that we need to load in a loop ? can we implement this using variables? or we need to write individual task for each table? Your feedback will be highly appreciated. thanks

Zarir Patel on 9/29/2008
very clearly explained and demonstrated video. Thanks

Emery on 9/30/2008
These training videos are fantastic. Thanks Brian! Keep them coming!

David Mark Everson on 9/30/2008
Brian will you do some work with the term extraction transform? Thanks David Everson

iskarta on 9/30/2008
Very Nice, Thank you very much

Philip on 10/1/2008
Very Good.

Brian Knight on 10/2/2008
Sayed, this can easily be done in SQL Server 2008 by hydrating the SQL Server 2008 lookup cache provider. In SQL Server 2005 you may have to use Merge Join instead to get selective on what you're pulling through for the comparison.

Brian Knight on 10/2/2008
David, thanks for the suggestion. I'll work up a few on that one over the next month.

Jon Jaques on 10/11/2008
Great!

Jon Jaques on 10/12/2008
Brian, is there some alternative to using a sql update statement in the Ole DB Command object? I have too many columns to update in this way, and don't want to embed the sql in this way anyhow. Why can't the Ole DB Destination handle this? Any ideas?

Jon Jaques on 10/14/2008
Brian, why wouldn't method number 2 in this video use a temp table? Shouldn't that temp table be created dynamically by the SSIS package?

Ben Agee on 10/16/2008
Great video Brian. What if the source database is across the WAN from the SSIS server and the target database? What is the best method to reduce network traffic?

Joseph Brosnan on 10/18/2008
Very good videos for those of us getting started with SSIS.

phani on 11/11/2008
THANKS, great work! -FROM INDIAN

Manuel Gamez on 11/19/2008
the instructor stutters too much.

Chathura on 11/25/2008
excellent

yadavrk on 12/17/2008
great tutorial

Shankar Jayaraman on 1/17/2009
That was a nice Demo

Tariq Bilal on 1/22/2009
Thanks Brian that was good.

priya on 1/26/2009
Thanks ....

Brian on 1/27/2009
It was OK. I tried this in 2008 and immediately ran into problems because the target table had too much data in it. There was no mention of this in the 2007 demo. Was caching used, partial caching, no cahing? The theory is sound and I like the technique but for me it simply does not work.

Stream is not available

Abha on 3/9/2009
Perfect, just what I needed. Thanks A LOT Brian!

Juan Lorenzoni on 3/27/2009
It was a great demo. One thing I do not know is where to get the training files from the demo. Could you help?

Juan Lorenzoni on 3/27/2009
I have found the files.

Anil on 4/13/2009
Good Video...Good Voice

vinaykotha on 6/2/2009
It was a good one but is the latest feature in SQL Server 2008 the "Merge Statement" is faster than this method?

Super Khool on 6/18/2009
I cannot download the sample code from this. Can you please make it available?

choudary on 6/18/2009
Great video, but getting a page not found error when I click the Sample code and package link, could you please load it again?

choudary on 6/18/2009
Could'nt find the topic in Expert SQL Server 2005 Integration Services, can you please tell me where it is? If not this book is there any other book?

shaun on 7/22/2009
very good example but can't download the zip file

Mark Gorczyca on 7/28/2009
Great video! Relatively short and sweet for someone who's trying to get started with SSIS for capturing changed records, and wants a scalable solution. Thanks!

Kashif on 8/6/2009
I have done similiar without doing sataging table, hope so it would be better. I will try it because i have millions of huge data.

Kevin Shen on 8/20/2009
Where Can I download the script used in the video demo?

Please demo link... A question: How this work in 2008??? Now exists a better way???

Rodney Workman on 9/4/2009
The link for downloading the sample code is not working. Also are there any updates to this for 2008?

bartss on 9/9/2009
ok

Wenda Stephens on 10/17/2009
I am excited about the ability to update & add so efficiently, alot faster then our present method. I just wonder if there is a way to find the deleted records also.. I would imagine there would be..

Mahmoud on 11/8/2009
this video was helpful for me becuase am searchin for CDC without timestamp

Deepti on 11/11/2009
It was good but I was looking for SSIS with CDC enabled database.

Jayesh on 12/1/2009
Nice video. Though I was looking for something different. This video is great help !

GY on 1/29/2010
Great video, very surprising there isn't an easier way to update.

Kaushik on 2/22/2010
Excellent.

Kaushik on 2/22/2010
Excellent.

Mukul Janeja on 3/13/2010
awesome but too fast. will be nice to know why 6 secs dropped to 1.5 sec.

Dhanabalan on 4/1/2010
It is very good to understand. Thanks

daniel on 4/29/2010
great video, the source download isnt working for me tho :(

Mike on 5/7/2010
Nice, however the conditional split is not working. It's only going to one destination when it should be going to both in my package since I have an update in both output names.

Hansjörg on 5/10/2010
Instead of using this quite "nasty" trick setting the loopkup error to ignore i would take a reqular SQL Server Merge Statement instead. Little harder to write but best performance and clear design

Kent on 5/31/2010
Another great presentation.

Kent on 5/31/2010
Fast...

patrick verroens on 6/17/2010
good

Charlie Bruno on 8/13/2010
excellent demostration.

Michael Clifford on 8/13/2010
Broken link to the sample package - Michael Clifford

Nitin on 8/13/2010
Thank you for showing few transformations, their usage and how to configure them.

Leigh Anne on 8/13/2010
I couldn't get the sample package to download. This was definitely helpful, but I'm trying to make it apply to my circumstance where I have over 200 fields in my source and permanent tables. If I'm going to use set-based, wouldn't it make more sense for me to just pull the whole file into a db table and wrap it in a stored proc rather than using the lookup transform?

Jim on 8/13/2010
Great Video. This is the level of stuff I like seeing.

Rob Schripsema on 8/13/2010
Great video -- thanks, Brian. But, as others have said, the link to the sample code is broken. Looks like www.WhiteknightTechnology.com is no longer in service...? Where is the white knight when you need him?

Rob Schripsema on 8/13/2010
Actually, the download is there, just at an address without the www. Try this: http://whiteknighttechnology.com/downloads/ChangeDataCaputre.zip

PD on 8/13/2010
Thanks

Don Gilman on 8/13/2010
WOW, this was meaty! Definately going to bookmark it for later assimulation.

Famson on 8/13/2010
Nice video Brian. Concise and informative. Keep up the good work. Rob, thanks for the url

Paul Kirkham on 8/15/2010
Excellent presentation just felt a little rushed but very clewar non the less

boreddy21 on 8/19/2010
very good we need somemore details(properties)

Paul Sprunger on 8/24/2010
Great job Brian. Thank you.

Steve Culshaw on 8/25/2010
Excellent run through of CDC ... but what was the other method that was hinted at ??

Chun Chang on 8/25/2010
Very useful!

MohanD on 10/19/2010
Very Good.

Michael on 10/21/2010
Where is the setup for CDC?

Dan on 10/29/2010
GREAT techniques. Thank you for sharing them.

sunil on 12/1/2010
good

umamahesh on 12/8/2010
nice video..

Jeff on 12/14/2010
This video was really informative. I didn't know there was a way to avoid using the sort data transformation.

prasad on 1/6/2011
nice video. very helpful ..!

Anil Babu on 3/9/2011
Really gud one- thanks

nilesh_jaybhay on 6/7/2011
awesome

Michael on 6/20/2011
It is not a CDC example. It is just an example of using SSIS to do an upsert.

Vinoth Kumar on 7/8/2011
Nice presentation !!

T. Carnahan on 9/21/2011
A little fast but understandable. Will have to review multiple times to get this down.

dip on 4/9/2012
Really Nice Article. Thanks, Dip
