I agree with Jack. It's like you wrote a product description for SSIS.
For going to Oracle, I'd suggest getting this third party destination device. Otherwise, moving the data to oracle...

Thanks Bart. Very useful information. I think I'll be staying away from the list all columns option though. I do like David Poole's tip up above. I need to remember...

You are quick, Gail! I haven't even been able to download the bloody thing yet, let alone get my virtual's upgraded.

Excellent article TJ. Congratulations on a well ordered process.
Any chance of posting the code for the procs that start the traces? I'm curious about some of the details of how...

Updating the stats will certainly lead to changes in the query plan, depending on what happened in the stats. It's possible that you had a plan that was working well...

Piling on.
I've seen that standard before. I don't care for it, but as long as it's applied consistently, it's readable and it won't hurt anything.

Usually just the opposite. Not updating stats for ages on end leads to slower & slower running procs and then the stats get updated and everything speeds up.
It could be...

Michael's works. Another way to the same window is to drill down on the table in question so that you see the "Constraints" folder. Right click and select "New Constraint..."
