Two day workshop delivered on site in your place of work.
You book a meeting room, invite the delegates and we’ll do the rest.
The sessions usually run from around 9.30 until 4pm, but we’ll fit it around you.
Two day workshop delivered on remotely, so your team can work at their desks, or from home.
However, experience shows that sometimes it works better when everyone’s together in a meeting room – no distractions means greater focus!
Get access to a suite of carefully curated video tutorials designed to take you through the training in simple steps.
We’ll have a weekly get-together to answer questions and review code, and to set expectations for the next week (usually to complete two videos).
We also offer ongoing support options to keep your team on track long after the formal training is complete.
This can be discussed on your consultation call.
chris lawlorApril 16, 2025Trustindex verifies that the original source of the review is Google. Nick is clearly very passionate about SQL and his knowledge of its workings is immense. Having benefited from a quick talk from him during my study at School of Code, I snapped up the opportunity for a day's intensive SQL deep-dive. It really opened my eyes to the power of SQL, having only previously used it in a very basic capacity over a day or two during the coding bootcamp and I'm looking forward to getting to grips with its more complex workings. Thanks again, Nick. Hamad AjmiApril 13, 2025Trustindex verifies that the original source of the review is Google. I signed up to the BI School in December 2024 and I don't regret!. I followed datacamp courses for a few months and I realised they are not reflective of what are considered 'intermediate' and 'advanced' skills in the real world. This is where The BI School is a breath of fresh air. From start to finish it's clear Nick is a expert in SQL and his excitement for teaching it is infectious. He makes no apologies for putting you through your paces and that's why the course is excellent. Don't worry if you struggle because Nick is more than happy to help. He is very friendly and reassuring. Even if you are unable to attend his online group sessions you can book 1-1 online sessions instead. The videos within the course are extremely detailed and will get you through the course too (good news for the introverts out there!). As someone who has done the Datacamp and the BI School course, I can honestly tell you The BI School blows it out of the water in every respect. Like the old saying goes 'You get what you pay for!' And it's 110% worth the money. Tarren GreenacreApril 13, 2025Trustindex verifies that the original source of the review is Google. Having participated in a one-day SQL course run by Nick, my knowledge and confidence using SQL has increased significantly. Nick's approach to the course was well structured and gave us plenty of practical exercises to apply our knowledge in addition to ample time for questions. A well-run course and one that I would recommend. Rehema RafiqzadahApril 10, 2025Trustindex verifies that the original source of the review is Google. The BI School is incredibly beginner-friendly and designed in a way that makes it very easy to understand, even for someone with no prior experience. The explanations are clear, straightforward, and engaging, which makes learning both enjoyable and effective. Nick, the instructor, does an amazing job breaking down complex concepts into simple, digestible lessons. One of the best parts is that he provides a practical lab at the end of each video, allowing students to immediately apply what they’ve learned and reinforce their understanding through hands-on practice. Ankita SharmaApril 7, 2025Trustindex verifies that the original source of the review is Google. I recently attended a one-day SQL training course run by Nick Holt at the BI School, and I couldn’t be more pleased with the experience. Nick is a fantastic instructor who managed to pack a remarkable amount of valuable content into a single day. The course significantly boosted my confidence and ability with SQL. Nick’s teaching style is clear, engaging, and practical. I’d highly recommend this training to anyone looking to sharpen their SQL skills, whether you're a beginner or looking to level up. Robert HawkerApril 6, 2025Trustindex verifies that the original source of the review is Google. I joined a 1 day SQL training course led by Nick Holt from the BI School. Nick delivered an excellent course which really transformed my SQL skills. I was impressed at how much ground we managed to cover in a single day and everything on Nick's syllabus was highly relevant to the reporting / analytics use cases which I work on. I highly recommend Nick's training. Robbie BeckwithApril 4, 2025Trustindex verifies that the original source of the review is Google. Took part in the first SQL in a day course. Started off with 0 experience of SQL and feel like I now know enough to make a good start at writing my own queries. I also have a ton of notes to look back on. Nick is a great teacher and I’d recommend the course to anybody looking to enter into the world of SQL HollyApril 4, 2025Trustindex verifies that the original source of the review is Google. I learnt a huge amount from Nick's 'SQL in a day' course. He is incredibly knowledgeable and luckily also extremely patient! ShekharMarch 30, 2025Trustindex verifies that the original source of the review is Google. The BI School's SQL Superhero Program is by far the best and well articulated I've come across. The course is developed in such manner that understanding SQL makes it easy to learn for all professionals (regardless of the level of SQL background you may have prior to joining this program). This also includes hands-on tutorial/assignment and personalized support when needed. I'm close to 50% done with the program and definitely recommend to anyone that's looking to not only understand the fundamentals of SQL language and tools within SQL Server vital for developing and optimizing SQL queries but to master it! Nick goes the extra mile in not just providing great support when needed but also regularly checks in to ensure you are not left behind and remain motivated. A great investment for anyone looking to master SQL from zero to hero! Nouer Uz-ZamanMarch 30, 2025Trustindex verifies that the original source of the review is Google. I have signed up to get improve and refrsh my SQL skills and Nick is a very experienced SQL Developer with emmence knowledge. I would definately recommend him if you are looking to improve or learn SQL.Load moreVerified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
