Now, switching from the professional third-person voice to the real-life first-person voice…

I live in an RV with my wife Kellyn, who also works at Microsoft.  Together, we’re traveling throughout North America, experiencing life in all of the different parts of this beautiful country.  Kellyn blogs and tweets as DBAKevlar, and we both blog about our life as RV nomads at DancesWithWinnebagos.com, and I am one very lucky guy to call her my wife.

I have two children, my son Peter and my daughter Marika, both of whom successful and wonderful adults, both living in the Denver area.  I am also proud of Kellyn’s son Sam (who is married and living in Connecticut), her daughter Rhys (who is a student in Denver), and her son Joshua (also a student in Denver).

On social media I tweet as @TimGormanTech and am also on LinkedIn.

For fun, in winter I snowboard the steeps and deeps, in summer I (road) bicycle long distances, and I play squash in any season when I can find facilities and someone of like mind.

    I watched your ODTUG presentation today about data warehouse partitioning. I have a question for you. If we range partition on the time dimension foreign key column in the fact table, will a query that filters on a time dimension column that is not the primary key will the query partition prune? Our experience is that it doesn’t. We use a surrogate key for the time dimension, not actual dates.

      Partition-pruning on a partitioned table (like a fact table) can only occur if an equivalence operation (i.e. col = value) is a filter predicate on the partition key column.

      Since a star transformation is performing a join operation to the partitioned fact table, and not filtering with an equivalence predicate, then the Oracle cost-based optimizer will be unable to recognize that partition-pruning should take place.

    Hi Tim, I enjoyed your presentation on data masking at GLOC May 17 in Cleveland. I would be interested in a copy of the Phoenix Project kindle book you mentioned. I hope your new mobile home adventure is a true success, and I will be checking out your website for tips on living this lifestyle, although on a smaller scale in my case! Thanks again.
