Oracle Database: SQL and PL/SQL Fundamentals

Database SQL and PL/SQL Fundamentals

Course Objectives

  • Run data definition language (DDL) statements to create and manage schema objects;
  • Run data manipulation statements (DML) to update data in the Oracle Database;
  • Use PL/SQL programming constructs and conditionally control code flow (loops, control structures, and explicit cursors);
  • Use cursors to process rows;
  • Create reports of sorted and restricted data;
  • Describe stored procedures and functions;
  • Describe the features and syntax of PL/SQL;
  • Design PL/SQL anonymous block that execute efficiently;
  • Display data from multiple tables using the ANSI. SQL 99 JOIN syntax;
  • Create reports of aggregated data;
  • Employ SQL functions to generate and retrieve customized data;
  • Handle runtime errors;
  • Retrieve row and column data from tables with the SELECT statement.

What you will learn

This Oracle Database: SQL and PL/SQL Fundamentals training delivers 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.

Benefits to You

Ensure fast, reliable, secure and easy to manage performance. Optimize database workloads, lower IT costs and deliver a higher quality of service by enabling consolidation onto database clouds.

Hands-On Practices

Demonstrations and hands-on practice reinforce the fundamental concepts that you’ll learn in this course. By enrolling in this course, you’ll begin using Oracle SQL Developer to develop these program units. SQL*Plus is available as optional tools.

Course Bundle

Note: This course is a combination of Oracle Database: SQL Workshop I and Oracle Database: PL/SQL Fundamentals courses.
