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).
