I enjoyed the balance of lectures and exercises. When I was stuck Luke was very good at helping me to understand the problem and work towards solutions which made a really positive impact on my understanding.

Lukasz was very patient and knowledgeable and made learning SQL very fun and informative. Easily one of the most rewarding training sessions of any subject I've had the pleasure of being part of!
Carwyn - Welsh Revenue Authority
Course - Transact SQL Basic
Phil was great! He was both patient and knowledgeable. The training went at a good pace, moving a team of mixed SQL abilities through the basics into more advanced SQL querying together. The exercises were an excellent way for us to commit our newly learned skills to memory, and Phil's instructions/class discussions on numerous ways to achieve the same thing were interesting.
