Business Intelligence training - Fast-track SQL

SQL Training

Fast track SQL course (3 days)

3 days

We recognise that not everyone can devote two days to attend our SQL Introduction course and another two days to sit on our two-day Advanced SQL course, so we've combined the contents together into this single, intensive three-day SQL course. The course will cover everything from creating basic SELECT statements all the way through to writing stored procedures and using CTEs, temporary tables and table variables.

Our fast-track courses are only available as tailored training, either at your premises or at either our London or Manchester venues (here's why).

Sample customer feedback

"Excellent course delivery and content."

Richard Teulon (Welsh Ambulance Service NHS Trust)

"I was worried about covering this subject (SSRS) as I knew nothing but now I feel like I know so much. I can't wait to get back and practice. "

Victoria Wass (CHP)

"The trainer was fantastic - very engaging and informative. Excellent training - thank you."

Victoria Elliott (Bloom Services)

"I thoroughly enjoyed the course. Wise Owl provided an excellent service from the booking process to the end of the course. The trainer had excellent interaction with everyone on the course and his knowledge was unquestionable. He was very engaging and I enjoyed the course due to his delivery on the subject. He was able to answer any question and apply it to real world examples. The course was presented at a pace which meant you could take in the information and had time to ask questions. Before the course I had been writing SQL scripts and was worried that I might not learn much from it, but I am happy to say I was able to learn new information that has already improved my effectiveness and I am already using these new skills. This was by far one of the most useful courses I have ever attended. I am looking forward to booking another course with Wise Owl in the near future. "
