About half of our courses are created bespoke for a single organisation, and either delivered onsite (usually somewhere in the UK, but we're willing to travel!) or online. For onsite courses we will usually provide and set up the necessary computers free of charge.

There are four main reasons why you might want to book tailored training like this:

  1. If you have 3 or more people, organising custom training will probably be cheaper than booking people individually onto a scheduled course.
  2. You'll be able to choose the content of any training, and be able to pause it for discussions on how you'll use software internally, or ask to take digressions.
  3. You may not be able to travel to our venues, so it might be easier to ask us to travel to you.
  4. You may not be able to make the dates of our published scheduled courses, and want to be able to choose when your training takes place.

If you'd like a quote for how much a tailored course would cost please let us know what you'd like to achieve and we'll get back to you (normally within half a working day).

About this Advanced SQL within Snowflake course

Click on one of the tabs below to see the given information about the course.

If you've already attended our two-day introduction to Snowflake SQL course you'll already know how to select data in SQL queries within Snowflake. This two-day advanced course aims to turn you into a fully fledged Snowflake SQL programmer. On the way you'll learn how to:

  • Create stored procedures and pass parameters to them

  • Work with programming concepts like variables, conditions and loops

  • Create your own user-defined functions to return single values and tables of data

  • Programmatically safely insert, update and delete data

  • Use temporary tables system functions and error-handling

This course uses (understandably) SQL for its stored procedure programming language.

Pre-requisites

You must already know how to create queries in Snowflake SQL to attend this course.

What you'll need to bring

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.

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 using our whizzy Wordsworth online training system, and these computers will have all of the necessary files and software installed.

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). We will also ask you whether you want to receive a printed copy of the course manual (and post this to you if you do).

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!

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.
