The SQL language seems simple – and that’s true. However, some topics can cause mistakes – things like NULL values, duplicate rows and missing rows, etc. This course covers the frequent mistakes, and how to avoid them.

You will learn SQL syntax applicable to most relational databases.  In the practice exercises you will use PostgreSQL, but the knowledge is easily transferable to other databases.  The standard SQL is the same in all ANSI-compliant SQL databases.

The course has English subtitles (closed captions) manually created!
