A couple of days went by this – a couple of useful days. Thanks to the employer and the course leader. I dare say that after this I get more power out of me.
Participant in company-specific SQL training

Well-structured course, very good teaching material, good lecturer and good SQL environment. The things I taught myself were already pretty much familiar, but I had learned them in a MySQL environment. Now the old things were repeated and I was able to learn a few dialect differences with SQL Server. In addition, it was really good that the exercise material was available all the time.
