Oracle Database: SQL and PL/SQL Fundamentals

WHAT YOU WILL LEARN

In this course, students learn the fundamentals of SQL and PL/SQL along with the benefits of the programming languages using Oracle Database technology. You'll explore the concepts of relational databases.

Learn To

  • Write queries against single and multiple tables, manipulate data in tables and create database objects.
  • Use single row functions to customize output.
  • Invoke conversion functions and conditional expressions.
  • Use group functions to report aggregated data.
  • Create PL/SQL blocks of application code that can be shared by multiple forms, reports and data management applications.
  • Develop anonymous PL/SQL blocks, stored procedures and functions.
  • Declare identifiers and trap exceptions.
  • Use DML statements to manage data.
  • Use DDL statements to manage database objects.
  • Declare PL/SQL Variables.
  • Conditionally control code flow (loops, control structures).
  • Describe stored procedures and functions. Retrieve row and column data from tables.
