Become a Certified Oracle PL/SQL Developer with Confidence

The Oracle 1Z0-149: Program with PL/SQL exam is designed for developers who want to validate their ability to write efficient, secure, and maintainable PL/SQL code in Oracle Database 19c environments.

Whether you’re working with stored procedures, database triggers, or advanced data manipulation logic, this certification confirms your real-world PL/SQL expertise. If you’re aiming for the Oracle PL/SQL Developer Certified Professional Certification, this exam is a critical step.

To strengthen your preparation, many candidates combine structured study with practice questions and downloadable PDF dumps, helping simulate real exam conditions and reinforce key concepts.

What You Will Learn: PL/SQL Skills & Exam Domains

This exam focuses heavily on hands-on PL/SQL programming and practical database development. Instead of theory alone, Oracle expects you to understand how PL/SQL behaves in real execution environments.

Writing Efficient PL/SQL Blocks and Control Structures

You’ll start with the fundamentals of PL/SQL block structure, including:

• Anonymous blocks and nested blocks
• Variable declarations using %TYPE and %ROWTYPE
• Conditional logic with IF, CASE
• Looping constructs such as FOR, WHILE, and cursor-based loops

Understanding execution flow is essential, especially when writing reusable and optimized code.

Working with SQL Inside PL/SQL

A large portion of the exam revolves around embedding SQL within PL/SQL:

• DML operations (INSERT, UPDATE, DELETE)
• Transaction control using COMMIT and ROLLBACK
• Using SELECT INTO for single-row queries
• Handling multiple rows with explicit and implicit cursors

You’ll also work with cursor attributes like %FOUND, %NOTFOUND, and %ROWCOUNT.

Exception Handling and Error Management

Robust PL/SQL code must gracefully handle runtime issues:

• Predefined exceptions like NO_DATA_FOUND, TOO_MANY_ROWS
• Custom exception creation
• Using EXCEPTION blocks effectively
• Logging and debugging techniques

This section tests your ability to prevent failures in production-grade database code.

Creating Stored Procedures, Functions, and Packages

You’ll need strong knowledge of modular programming:

• Creating and invoking procedures and functions
• IN, OUT, and IN OUT parameters
• Package specification vs package body
• Overloading subprograms

Oracle emphasizes reusable, maintainable code design in enterprise systems.

Working with Triggers and Advanced Database Features

Triggers are a key part of Oracle database automation:

• Row-level vs statement-level triggers
• BEFORE vs AFTER triggers
• Managing mutating table errors
• Using compound triggers

You’ll also encounter advanced features such as:

• Collections (VARRAY, Nested Tables)
• Records and user-defined types
• Dynamic SQL using EXECUTE IMMEDIATE

Managing Performance and Optimization

Efficient PL/SQL code matters in real systems:

• Bulk processing with BULK COLLECT and FORALL
• Reducing context switching between SQL and PL/SQL
• Using bind variables
• Profiling and tuning PL/SQL code

Performance-focused questions often test practical optimization strategies.
