Course Description

Prepare to pass exam: Oracle Database Program with PL/SQL

Oracle Advanced PL/SQL Developer Certified Professionals demonstrate expertise in database-centric Internet applications for Oracle Database 10g, 11g and 12c.

To successfully pass the Oracle Database Program with PL/SQL exam, dive deep into topics such as managing dependencies, optimizing code for performance, and using dynamic SQL for complex data operations. It's also important to understand working with cursors, collections, and large objects (LOBs), as these are frequently covered in the exam. Practice creating robust PL/SQL applications that handle exceptions efficiently and follow best practices in security and performance tuning. Leveraging Oracle's official study materials, sample exams, and hands-on labs will further enhance your preparedness. Focus on understanding real-world applications of PL/SQL programming to excel in practical scenarios.

Additionally, ensure you are comfortable with advanced PL/SQL features such as triggers, procedures, and packages, which are key components of the exam. Practicing with real-world coding challenges can help sharpen your problem-solving skills. Stay updated with the latest Oracle documentation and resources to align with the most current exam objectives and best practices.

Creating Functions

• Differentiate between a procedure and a function
  
• Describe the uses of functions
• Work with functions (create, invoke and remove functions)

Creating Packages

• Identify the benefits and the components of packages
  
• Work with packages (create package specification and body, invoke package subprograms, remove a package and display package information)
• Overload package subprograms and use forward declarations

Working with Packages

• Use package types and variables
  
• Use packaged constants and functions in SQL
• Use ACCESSIBLE BY to restrict access to package subprograms

Using Dynamic SQL

• Describe the execution flow of SQL statements

Design Considerations for PL/SQL Code

• Create standard constants and exceptions
  
• Write and call local subprograms
• Control the run-time privileges of a subprogram
• Perform autonomous transactions
• Use NOCOPY hint, PARALLEL ENABLE hint and DETERMINISTIC clause
• Use bulk binding and the RETURNING clause with DML

Creating Compound, DDL, and Event Database Triggers

• Create triggers on system events
• Describe different types of triggers and their uses

Using the PL/SQL Compiler

• Describe the PL/SQL compiler and features
  
• Use the PL/SQL compiler initialization parameters
• Use the PL/SQL compile time warnings

Managing PL/SQL Code

• Describe and use conditional compilation
  
• Code-based access control: granting roles to program units
