Introduction to SQL

Descriptions

This Oracle Database: Introduction to SQL training helps participants write subqueries, combine multiple queries into a single query using SET operators, and report aggregated data using group functions through hands-on exercises. The course enables learners to understand the basic concepts of relational databases to help developers produce refined code, create reports with sorted and restricted data, and run data manipulation statements (DML). Participants will also learn how to retrieve row and column data from tables, control database access to specific objects, and manage schema objects using data dictionary views. In addition, the training covers controlling privileges at both the object and system level,
creating indexes and constraints, altering existing schema objects, and creating as well as querying external tables.
