Advanced SQL training course contents

Learning to write SQL involves two things.  First, you need to learn how to write SELECT statements to interrogate your corporate database (including joining tables, setting criteria and grouping data).  For this our two-day Introduction to SQL course is ideal.  This is where most people choose to stop.

However, SQL is so much more than just the SELECT statement.  Our advanced SQL course will teach you how to program in SQL, including:

  • Creating and running stored procedures (programs in SQL), including passing parameters

  • Creating your own user-defined functions

  • Inserting, updating and deleting rows and tables

  • Working with temporary tables and table variables

  • Creating Common Table Expressions (CTEs)

You should only consider attending this course if you already understand how to select data in SQL (including joining tables).

Stored procedures

  • Creating stored procedures
  • Executing stored procedures
  • System stored procedures


  • Declaring variables
  • SET versus SELECT

What other people have said

Our thanks to everyone who agreed to share their thoughts. All of the following reviews are from the last 3 calendar years:

"This course was very useful and helpful for the work that we will be undertaking at the council in the future. Our trainer was very knowledgeable, very helpful and delivered the course at a very good pace. He was able to answer any questions I had and was able to advise on how we are using the system for our performance data. Will definitely be doing another course with you in the future. I have previously done the Introduction to SQL course, so wanted to expand my knowledge further and learn how I could implement all the different techniques into our own system. I will be exploring the Power BI courses once we are in a position to do so."

Scott Lea (City of Lincoln Council)

"Really enjoyed this course and took a lot from it. Thank you again."

Mariannina Pascale (Frimley Health NHS Foundation Trust)

"I really enjoyed the course. Thank you for all the additional information and the videos you have available. I almost chose the beginner course but after a great chat with one of your trainers, I think I correctly chose the advanced course. I've also had great feedback from other employees at my company who have also taken a course with Wise Owl. Great staff at every point through the journey."

Kyle Anabossi (Hoist Finance)

How our training courses work

Below are some notes on how Wise Owl courses work, to help you decide whether they're for you or not.

What you'll need

If you book on a classroom course, the only thing you need to bring to the course is ... yourself! We even provide a notepad and a suprisingly nice pen for you to take notes with.

For online training you'll need two things:

  1. A good internet connection (otherwise you'll have a frustrating time); and
  2. A second screen (a requirement, not a nice-to-have!)

You can see full details of our online course requirements here.

When you book a place

If you book a place on one of our courses:

  • For classroom courses we will send out a joining email. That's it!
  • For online courses we will get in touch to organise a half-hour pre-course check to iron out any connection problems before the course (rather than during it).

Whatever type of course you book, we will also send you out a reminder a few days before the course is due to take place - not that (we hope) you'll have forgotten!

What you won't need

For classroom training, you won't need a computer - we (obviously) will provide that. However, you're welcome to use your own laptop if you prefer, providing that you have the correct software installed.

For online training you will need a computer, but you won't need to have any software installed.  This is because you'll use Windows Remote Desktop to connect to our computers, and these will have all of the necessary files and software installed.

The start of the course

For online courses you will be able to join up to half an hour before the course begins. This will give you time to:

  • familiarise yourself with the set-up;
  • meet your trainer; and
  • get to know the other delegates!

For classroom training it's always nice if people arrive a bit early too, to give people time to meet each other (and drink coffee).

You'll be given a full colour courseware manual, an exercise booklet to go with the course and a USB stick for taking course files away (we'll post all this to you for online courses).

After the course

After the course finishes you'll receive a digital certificate proving your attendance (we will gladly send a paper copy on request also).

We don't have any formal arrangement for answering questions after the course, but if you get stuck on something and email your trainer they should (and nearly always do!) respond as quickly as their training schedule allows.
