This week I discuss a question that I've gotten in many forms over the years - a lot of the scenarios are so specific that it's hard to keep them anonymous, but they can be generalized as a bigger problem: how do I deal with being responsible for things that I can't fully control? DBAs have huge responsibilities, so this is a common, frustrating scenario. In this episode, I talk about a few times that I've experienced this in my own life, what techniques didn't work, and what strategies were more effective.

Our question this week comes from someone who's excited to be on a healthy career path, building their work experience as a DBA. They're worried: will lacking a college degree block their career growth down the line? I talk about my experience and also check out current job listings to answer the question.

In this episode, I talk about how to strategize for and prepare for Microsoft Certification exams, using the Database Fundamentals exam as an example.

Our question this week comes from an IT pro who would like to be self-employed. In this episode, I talk about three big things you need to think about to start working for yourself, and two possible paths to get there.

A few folks have asked: will auto-tuning and adaptive query plans mean the end of performance tuning jobs in SQL Server? In this week's episode, I talk about why I'm excited about those features rather than afraid of them. Digging into this problem, I share the #1 mindset problem I had as a DBA, why this mindset is so common among database professionals, and a daily habit that can change your approach to new technology.

Are you worried that you talk too fast when you give a speech, talk, or presentation? Is fear being a fast-talker one of the concerns that keeps you from getting started with public speaking? In this episode, I give you simple, practical tips that I've used to successfully improve the way I give presentations. Four years ago, I got frustrated feedback from listeners who had a hard time keeping up with my mouth; now I get congratulations that the pace was great.

In this week's episode, I'm not answering a reader's question. Instead, I'm talking about my personal experience with anxiety. This episode touches on on healthcare, religion, and squishy emotions -- and there's at least one curse word. I don't talk tech in this episode. (Don't worry, there's more of that coming in future weeks.)

SQL Server Service Packs are going away, starting with SQL Server 2017. I talk about why I think this is a good thing, and discuss Cumulative Updates, Service Packs, and the process of updating SQL Server.

People have strong feelings about SQL Server Management Studio: they love it AND they hate it. In this week's episode, I talk about why people have such conflicting feelings about SSMS, and how to work it all out.

A query is slow, and you figure out how to collect the query execution plan. Now what? In this episode I talk "big picture" about what execution plans are, what "cost" is, why to collect "compiled for" values, and the steps I take to analyze execution plans while performance tuning queries.

As a SQL Server DBA, do you need to be a killer with scripts? In this episode I talk about how much you need to know about PowerShell, and examples of ways I personally use (and struggle with) PowerShell.

I'll be attending and presenting at the SQL PASS Summit in Seattle Washington this year from Oct 31-Nov 3. In this week's episode, I share why I'm excited about going, and why I've purchased a seat for a pre-conference session. (Spoiler: pre-cons are awesome!) I also give my tips on how to get the MOST value out of a big conference like the PASS Summit.

Over the years, readers have asked me: "How do you stay motivated?" Sticking with a learning plan, blogging, or becoming a public speaker isn't easy. In this episode I share how I think about motivation and what keeps me going.

This week's question from a reader: how do I deal with interview questions asking about real-world scenarios when I've faked three years of experience on my resume?

In this episode, I talk about three articles written by members of the SQL Server community on interviewing that I can't stop thinking about: "Playing the Third Party Recruiter Game", by Adam Machanic - http://sqlblog.com/blogs/adam_machanic/archive/2017/08/08/playing-the-third-party-recruiter-game-t-sql-tuesday-093.aspx "I Hate Interviews", by Rob Sewell - https://sqldbawithabeard.com/2017/08/08/i-hate-interviews-tsql2sday/ "Learning to say 'No'" by Mark Broadbent - https://tenbulls.co.uk/2017/08/08/learning-to-say-no/

Hear the story of an interview where my dreams were crushed - and what I learned about interviewing from the experience.

You've got some troubling wait stats in SQL Server. How can you tell which queries are causing those waits? Kendra discusses the pros and cons of different techniques to track down the cause of both common and tricky waits in SQL Server, including CXPACKET, PAGEIOLATCH, LCK, RESOURCE_SEMAPHORE, and THREADPOOL waits.

If you need to add, remove, or replace hints from ad-hoc queries and you can't change the code, plan guides can help. See a demo of removing hints from parameterized TSQL run from an application, and get tips on how to make your plan guides work in SQL Server.
