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.

I hate saying no

I really do. There is a joke that DBAs say no to everything and there is some truth to that. But if I say No it’s for a reason. A good one. Because I hate disappointing people, and I hate making their work harder. But I promise I have a… Read more

Master_Views: master_objects, master_tables, etc

There is a highly useful system view called sys.master_files. If you’ve never encountered it before it returns a list of all files from all databases. It’s been somewhat frustrating to me that there is no similar master_objects, master_tables, master_indexes etc. So what does a dev/dba do? Create them! So… Read more

Re-Evaluating Best Practices

I was reading a blog post from my friend Randolph West (b/t) on Best Practices and a thought struck me.

Starting with Randolph’s definition of a best practice (he got it from Wikipedia and it’s more than good enough)

A best practice is a method or…

RAID your backups

Let’s start with a very brief definition of some RAID levels.

  • RAID 0 : Stripe your data across multiple disks. Writing a portion of the data to each disk. This improves performance but increases the risk of corruption.
  • RAID 1 : Mirror your data across multiple disks. This duplicates…

Comparing the contents of two tables

I’ve been working on tuning a query for the last week and I’ve had to make several changes to the query’s logic. I’m always a little nervous when making those types of changes so I try to do some careful testing before I even suggest the changes to the developers.… Read more

Getting your Cloud on

One of the things I like best about joining in on Adam Machanic’s (b/t) TSQL Tuesday blog party is that it can force you to explore things you haven’t tried before. Well that’s exactly what Wendy Pastrick (b/t) wanted us to do.… Read more

Grant Deny Revoke

It always amazes me how often these three commands get confused. Heck it amazes me how long I confused them.

TL;DR; GRANT and DENY are opposites. GRANT applies a positive permission, DENY a negative permission. DENY will always override GRANT. REVOKE is the opposite of GRANT and DENY. It removes… Read more

Remove files from a filegroup

You have a database with one or more filegroups, and one or more of those filegroups has multiple files. You’ve decided that you don’t actually need some of those additional files and want to get rid of them. Here are some steps you can follow.

Assume there are 5 files… Read more
