Podrobnosti:

This course introduces students to PL/SQL and explains the benefits of this programming language. Participants learn to create PL/SQL blocks of application code that can be shared by multiple forms, reports, and data management applications. The course also imparts how to create anonymous PL/SQL blocks, stored procedures, and functions. Participants learn about declaring identifiers and trapping exceptions. Demonstrations and hands-on practice reinforce the fundamental concepts.

Students use Oracle SQL Developer to develop these program units. SQL*Plus and JDeveloper are available as optional tools.

This is appropriate for a 10g and 11g audience. There are minor changes between 10g and 11g features.

• Conditionally control code flow (loops, control structures)
• Use Explicit Cursors
• Handle runtime errors
• Describe stored procedures and functions
• Work with Composite Data Types
• Declare PL/SQL Variables
