It's important for developers to understand the basic concepts of relational databases. This course helps you write subqueries, combine multiple queries into a single query using SET operators and report aggregated data using group functions.
Learn Advanced Features of SQL
You'll also learn to create indexes and constraints, while altering existing schema objects. Expert instructors will teach you how to create and query external tables, along with the advanced features of SQL.
Expression Support in SQL
This course also discusses how to use the regular expression support in SQL. Learn to query and manipulate data within the database, use the dictionary views to retrieve metadata and create reports about their schema objects. You'll also explore some of the date-time functions available in the Oracle Database.
Controlling privileges at the object and system level are also dealt with in detail. This course is a combination of Oracle Database: SQL Fundamentals I and Oracle Database: SQL Fundamentals II courses.
