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.

Certificates, Proxies and Jobs! Oh My!

Oh Noes! I have a job that requires me to run an SSIS package, cmdshell script, etc. And I need them to have specific file level permissions! What do I do! I know I need to run my job/job step as a specific AD/Windows user but I don’t see how… Read more

Get your SQL Server MCSA without taking the BI exam.

I’m a big fan of certifications as a training exercise. However not everyone has the same interests. With the new MCSA (well new 6-8 years ago) we were required to take the data exam (70-461), the admin exam (70-462) AND the BI exam (70-463). I know a number… Read more

Why my primary test environment is case sensitive.

Me: I think I’m going create a new playground instance.
Myself: Make sure you use a case sensitive (CS) collation when you install it!
I: You mean a collation that forces us to pay attention to the case of the variable names (for example)? So that something like this returns… Read more

How do I rename a column?

Everyone makes mistakes right? And sometimes you create an object and decide later that you messed up and need to rename it.

EXEC sp_rename 'OldName','NewName'

This works for tables, stored procedures, views etc, but there are a few things to be careful about. It doesn’t change the code behind code… Read more

Modulo!

I love this somewhat obscure mathematical operator. All it does is return the remainder of a division statement but even though it’s pretty basic most people I talk to have never heard of it. The format is

dividend % divisor = remainder

DECLARE @remainder INT
DECLARE @dividend INT = 10…

The risks of Delayed Durability

It’s T-SQL Tuesday again and this month we are hosted by Jens Vestergaard (b/t) who want’s us to talk about our favorite SQL Server feature. Great topic, but a really difficult choice. There are so many great features of SQL Server.
Some of my favorites include: Read more

Name the schema when you create an object (or else)

This is one of those frequently ignored best practices.

When you create an object, specify the schema where it will be created.

I should also point out

When you reference an object (in a query for example), specify it’s schema.

I know I have a tendency to forget this myself.… Read more

Complex/Conditional ORDER BYs

Typically it’s considered best to run your queries without an ORDER BY and let the application do any sorting needed. Sometimes though it’s faster and easier to let SQL handle the sorting for you. And that’s fine. SQL is very good at sorting.

Simple sorts are pretty easy. In the… Read more

Hidden code in AdventureWorks

I’ve playing around with AdventureWorks and managed to found some hidden code! Truly odd stuff. I’m so shocked I couldn’t wait until the time I usually post.

So if you take the x character of the first character column of each table (where x is object_id % len(column) ), merge… Read more
