SQLStudies

My name is Kenneth Fisher and I am Senior DBA for a large (multi-national) insurance company. I have been working with databases for over 20 years starting with Clarion and Foxpro. I’ve been working with SQL Server for 12 years but have only really started “studying” the subject for the last 3. I don’t have any real "specialities" but I enjoy trouble shooting and teaching. Thus far I’ve earned by MCITP Database Administrator 2008, MCTS Database Administrator 2005, and MCTS Database Developer 2008. I’m currently studying for my MCITP Database Developer 2008 and should start in on the 2012 exams next year. My blog is at www.sqlstudies.com.

T-SQL FizzBuzz

I was looking around for something to write about this evening and came across one of Russ Thomas’ (b/t) old monthly challenges (Feb 2016).

Why shouldn’t I shrink my database log file?

Dynamic SQL and the joys of QUOTENAME

I’m a big fan of dynamic SQL. In the past I’ve written a How to, a Best Practices and even a Generic Dynamic SP although that last one was a bit so so in my opinion. Depending on what type of dynamic code you are writing QUOTENAME will be… Read more
