Online Training
Advanced SQL
Live online training course - classroom version also available
£650 + VAT (where applicable)
Two days (09:30 to 16:30 UK time each day)
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).

How our live online training courses work
We've published a full summary of what it's like to attend a Wise Owl course online - here are the main things you need to know.
You'll need three things for the course:
- A computer (obviously) running Windows.
- A good internet connection.
- A microphone and (ideally) webcam.
In addition you'll find the course very difficult without an additional monitor (so that you can participate in the course on one screen, and use the software you're learning on the other).
Within a few hours of your booking a place on one of our online courses, we'll be in touch to get you set up correctly. This usually takes about half an hour, and can be done at any mutually convenient date/time.
A few days before your course begins you'll receive a parcel in the post (free for UK bookings) containing:
- A full colour courseware manual;
- An exercise booklet to go with the course; and
- A USB stick containing the files for the course, should you need a back-up.
Your parcel will even include a Wise Owl Sheaffer biro (they're good; trust us) and pad.
You won't need to install any software at all on your computer. 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; and
- we use Teams for our online training, which you can run through most modern browsers.
On the day of the course itself you will be able to join the course up to half an hour before it begins. This will give you time to:
- familiarise yourself with the set-up;
- meet your trainer; and
- get to know the other delegates!
After the course finishes you'll receive an electronic certificate proving your attendance (we will gladly send a paper copy on request also).
