New live online training class in October: Fixing Slow Queries, Inefficient Code, and Caching/Statistics Problems

Continuing our series of live, online classes, Erin, Jonathan, and Kimberly will be delivering their new IEQUERY: Immersion Event on Fixing Slow Queries, Inefficient Code, and Caching/Statistics Problems in October! The class will be delivered live via WebEx on October 23-25 (roughly 12-13 hours of content including Q&As; about the same as two full workshop days!) and the attendees will have lifetime access to the recordings following the end of the class.

Rather than have people try to watch a full day of training at their computer for one of more days, the class will run from 10am to 3pm PST each day, with two 90-minute teaching sessions, each followed by Q&A, and a lunch break. We chose to do this, and to spread the class over a few days, so the times work pretty well for those in the Americas, Africa, and Europe. We also realize that this is complex content, so want to give attendees time to digest each day’s material, plus extensive Q&A.

Here are some select quotes from prior attendees of Erin’s/Jon’s/Kimberly’s online classes:

  • “Extremely pleased with the course. FAR exceeded my expectations.”
  • “Well worth the time and expense to attend. Would highly recommend this to others.”
  • “Great course – very informative – very great instructors – I am sure to be back!”
  • “Great course. Good new info for me, plus refresher on other info. Thanks!”
  • “Both Erin and Jon have a vast knowledge of not only SQL Server & tools, but also effective presentation.”
  • “Thanks for taking the time to better my knowledge of SQL and allow me to better my career.”
  • “Kimberly is incredibly knowledgeable and was able to adapt the techniques to all the different scenarios presented to her.”
  • “Great course. I could hear clearly, the content was relevant to current day problems, and provided clear instruction.”
  • “Loved the online aspect. It felt like I was there with the question ability and having the questions just answered right there. I felt I had a voice and could ask anything and the ability to watch it later made it totally worth the registration.”
  • “I really enjoyed the ability to ask questions as the course went along so that I didn’t forget what I wanted to ask while you were teaching. This allowed for questions to come through and class to continue until a good stopping point to answer the questions. Plus having the questions written from other attendees was nice for future reference instead of trying to remember from an in-person class discussion.”

The class is split into three parts, with each part taught by a different instructor:

  • Part 1/Day 1: Capturing Query Information and Analyzing Plans (presented by Erin Stellato)
    • Baselining options and considerations
    • Sources of query performance data (e.g. DMVs, Extended Events or Trace)

    • Operators and memory use
    • Predicates and filters
    • Parallelism in plans
  • Part 2/Day 2: Removing Anti-Patterns in Transact-SQL (presented by Jonathan Kehayias)
    • Set based concepts for developers
    • Design considerations that affect performance
    • Reducing/eliminating row-by-row processing
      • CURSORs and WHILE Loops, scalar UDFs, TVFs
    • Understanding Sargability and eliminating index scans in code
    • Profiling during development and testing properly
  • Part 3/Day 3: How to Differentiate Caching / Statistics problems and SOLVE THEM! (presented by Kimberly L. Tripp)
    • Troubleshooting Statement Execution and Caching
      • Different ways to execute statements
      • Some statements can be cached for reuse
      • Statement auto-parameterization
      • Dynamic string execution
      • sp_executesql
      • Stored procedures
      • Literals, variables, and parameters
      • The life of a plan in cache
      • Plan cache limits
      • Bringing it all together
    • Troubleshooting Plan Problems Related to Statistics (not Caching)
      • Statement selectivity
      • What kinds of statistics exist
      • How does SQL Server use statistics
      • Creating additional statistics
      • Updating statistics

The price of the class is US$699 (or US$599 for prior live, online attendees) and there’s also a combo price for all three new classes announced today.

You can get all the details here.

The class was also announced in our newsletter today, with a US$100 discount for those people who received that newsletter, valid through the end of June. All future live, online classes will always feature a discount for newsletter subscribers.

We decided to start teaching some live, online classes as we recognize that not everyone can travel to our in-person classes, or take that time away from work or family, or simply have travel budget as well as training budget. People also have different ways they learn, some preferring in-person training, some preferring recorded, online training, and some preferring live, online training.

We’ll be doing more of these so stay tuned for updates (and discounts through the newsletter).

We hope you can join us!

New live online training class on using Query Store in May!

Continuing our series of live, online classes, Erin will be delivering her new IEQS: Immersion Event on Solving Common Performance Problems with Query Store in May! The class will be delivered live via WebEx on May 22-23 (roughly 12-13 hours of content including Q&As; about the same as two full workshop days!) and the recording will be available to attendees for six months following the end of the class.

  • “Great course. Good new info for me, plus refresher on other info. Thanks!”
  • “Both Erin and Jon have a vast knowledge of not only SQL Server & tools, but also effective presentation.”
  • “Thanks for taking the time to better my knowledge of SQL and allow me to better my career.”

New Pluralsight course: Analyzing Query Performance for Developers

Erin’s latest Pluralsight course has been published – SQL Server: Analyzing Query Performance for Developers. It’s four hours long, and from the course description:

Developers are sometimes charged with fixing performance issues, and they have no idea where to start. They’ve never seen a query plan, or when they look at one they’re not sure what it *really* means. The developers know how long it takes for a query to execute, but they don’t know how to see how much IO, CPU, or memory it uses. And sometimes they just create an index and that seems to fix the problem (even though they have no idea why!). In this course, SQL Server: Analyzing Query Performance for Developers, you’ll learn about all the data that SQL Server generates when a query executes – it’s more than just the query plan – and you’ll learn where it exists and how to find it. First, you’ll discover what the data represents and how to read a query plan. Next, you’ll explore some of the query plan operators you’ll see most often. Finally, you’ll learn what information is included in the plan, which may not be immediately obvious, but can be extremely valuable when troubleshooting. When you’re finished this course, you’ll have the skills and knowledge to start examining and understanding query plans and making query changes for better performance!

The modules are:

  • Introduction
  • Finding Information About Queries
  • Understanding Query Performance Metrics
  • Reading Query Plans
  • Operators in a Query Plan
  • Important Information in a plan

Check it out here.

We now have more than 165 hours of SQLskills online training available (see all our 54 courses here), all for as little as $29/month through Pluralsight (including more than 5,000 other developer and IT training courses). That’s unbeatable value that you can’t afford to ignore.

Enjoy!
