SSIS Webinars, tablediff, and Free Zoom Tool

I had the opportunity to attend 3 of 5 free webinars on SSIS presented by Brian Knight of Pragmatic Works. The 2 I chose not to participate in were introductory in nature, and I have some experience with SSIS. I attended Administering and Deploying SSIS Packages, Performance Tuning in SSIS, and SSIS for the DBA. I enjoyed each of the webinars and picked up some good tips. I enjoy taking any opportunities, particularly free ones, to expand my toolkit and knowledge base. I appreciate Brain and co-workers taking the time to present the webinars as I know that there had to be a lot of time and effort put into doing them. I hope it pays off for them in their business as well. I believe that the goodwill it will. Check out the Pragmatic Works web site as they offer some very good custom SSIS tasks for free! They also offer some other commercial product as well.

I actually used something I learned in one of the Webinars today, Webinar SSIS for the DBA,. I used an Execute SQL Task to populate an object variable with a list of schemas and tables and then used a For Each Loop Task to loop through the result set and use the Execute Process Task to run the tablediff utility Microsoft has included with SQL Server 2005 (I read about it in Benjamin Wright-Jones' blog earlier today). It is a command line utility that compares 1 set of tables (source and destination) and I wanted to compare all the tables in my database to my development database so I needed the loop. Tablediff compares the schemas and if they are different will return an error, "can not compare the table x to table y because the schemas are different". If the schemas are the same it will, depending on the parameters you supply, show any differences in the data and prepare a T-SQL scipt to synchronize the data. I actually was only interested in comparing the schemas and, not having read all the documentation, was hoping it would report those differences as well. Maybe in a later version of SQL Server a schema comparison tool will be included (sorry Red Gate). It was still a good exercise, and knowing about the tablediff utility will probably come in handy later.

One last thing, Brian used a nice free tool to zoom and markup during his presentation. It is called ZoomIt and is by Sysinternals (now part of Microsoft). I would recommend it to anyone who give presentations as it really helped us see what Brian was doing.


  1. Jack, just a small typo ;)
    "I appreciate Brain" should be
    Brian.. ;)

  2. This sounds exactly what I ma looking for. Can you share the code/provide examples?

  3. I'm not sure what code you want me to share. I no longer have the SSIS package as it did not do what I wanted. I could possible put something together if I had your email.

So what do you think I am?
