Sample customer feedback

"The Introduction to SQL course was really good, it covered all the basics and there was a wide range of examples shown by the trainer, as well as exercises from the Exercise booklet. The trainer was very knowledgeable in the subject and answered questions throughout the course on topics not covered on the course itself. On the Advanced SQL I really like how everything is explained and the trainer checking how everyone is getting on with exercises."

"Great website, easy to use and informative."

Claire White (DFDS Seaways)

You should only attend this course if you have either attended our two-day introduction to SQL course or if you are comfortable creating queries using SQL. The course shows how to write the dialect of SQL used by Microsoft (called T-SQL), using SQL Server Management Studio as a development environment.
