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.

How do I look at my error log if SQL won’t open?

Quick and easy post today. Hopefully you’ve opened the error log on a SQL instance. However, what happens if you don’t have the log viewer in SSMS? In fact, the instance won’t come up at all so you really need to see what went wrong.

What is the Object Explorer Details tab good for?

For a long time there I would see the Object Explorer Details tab show up when I opened SSMS (SQL Server Management Studio) and I would immediately close it. I couldn’t think of a single use for this view that seemed to be just another way to see the list… Read more

Highlighting sp_spaceused

I’ve been using sp_spaceused a lot recently so I thought I would bring it up again. Basically it’s a quick way to bring up the size of things. Specifically:

  • Tables
  • Indexed views

Generate a random number of children for each parent

I was asked an interesting question the other day.

Is it possible to get a different random number of rows back from each application of a cross apply?

The purpose is to create some random demo/testing information. This is one of those cases where an example may be needed for… Read more

SQL Homework – October 2018 – Time for an upgrade
