Thanks. I read it and all comments that followed. It is not the best write-up on CDC. I appreciate the pointer though, now I know that such a capability exist.


That really is not so good of an article...never read that before either. There is a discussion up here that compares trigger and cdc that's pretty good if you wanted to compare and understand the different approaches. If you only want data and not who did what then CDC may work. It's not a replacement for using triggers and wasn't intended to be - it won't capture things like user, spid, application, etc that the poster requested. So it wouldn't work in this case if you read the posters request. It's really data only. It's based on reading the log so it's going to be limited in that respect. I haven't played with using extended events for something like this request but that is an interesting approach, I kind of like the thought of that.
In any case, the approach really depends on what is needed with the auditing, what's being audited, etc. Here is a link to that discussion - which has some links to real CDC articles:

And also, CDC (Change Data Capture) is only available in the Enterprise Edition of SQL Server.

Cool

Not quite true anymore. As of 2016 SP1, it's also available in the Standard Edition.

Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
If you think its expensive to hire a professional to do the job, wait until you hire an amateur. -- Red Adair

Well, I guess the documentation I read on Microsoft was wrong. Couldn't find where I read it when I posted this, so maybe I just found an old page some how. I did find where it is now available beginning in 2016 SP1.
