Oracle Database – Introduction to SQL Ed 2

In this course you will learn how write subqueries, combine multiple queries into a single query using SET operators and report aggregated data using group functions. This course is based on hands-on exercises.

You will also learn how to understand the basic concepts of relational databases ensure refined code by developers, create reports of sorted and restricted data, run data manipulation statements (DML), control database access to specific objects, manage schema objects, manage objects with data dictionary views, retrieve row and column data from tables, control privileges at the object and system level, create indexes and constraints; alter existing schema objects, create and query external tables.
