In this course, you'll get an in-depth look at the SQL SELECT statement and its main clauses. The course focuses on big data SQL engines Apache Hive and Apache Impala, but most of the information is applicable to SQL with traditional RDBMs as well; the instructor explicitly addresses differences for MySQL and PostgreSQL.

Great course! I would just add 1 more full business task for practicing before the final one. Anyway, I find the course very useful with clear and understandable explanation.\n\nThank you!
How amazing the course was! From the video lectures, the reading materials, to the practical exercises and the teachers as well, everything was fantastic in this course. Highly recommended!
Great overview of SQL. Some decent hands-on and well thought-of quiz questions. Recommended even for people who might know SQL somewhat, but never had a structured overview of it.
Excellent course even if you have an sql knowledge with a bachelor. Especially the part where it explains the handling of NULLs which is not obvious and I didn't know about.
