Mastering Oracle SQL is therefore guaranteed to open exciting opportunities.

You will then perform aggregation and combine tables. The last chapter will have you handle missing values and convert data. By the end of this course, you will understand how Oracle processes SQL queries and will have a solid foundation in Oracle SQL.
