Hands-On Practice is Critical
- Write at least 100+ PL/SQL code examples across all topic areas
- Use Oracle Live SQL or local Oracle XE for daily coding practice
- Type code manually rather than copying—builds muscle memory for exam
- Create a personal code repository organized by topic for quick review
- Practice debugging broken code—exam may include identifying errors
Master the Syntax Details
- Memorize exact syntax for cursors, exceptions, and stored program units
- Know when semicolons are required vs optional in PL/SQL blocks
- Understand differences between := (assignment) and = (comparison)
- Learn all cursor attributes (%FOUND, %NOTFOUND, %ROWCOUNT, %ISOPEN)
- Memorize parameter mode keywords (IN, OUT, IN OUT) and their behaviors
Focus on Exception Handling
- Memorize all predefined exceptions and triggering conditions
- Understand exception propagation rules in nested blocks
- Practice RAISE_APPLICATION_ERROR with different error numbers
- Know how to create and handle user-defined exceptions
- Study WHEN OTHERS handler placement and best practices
Packages Deserve Extra Attention
- Build at least 5 complete packages with specifications and bodies
- Practice overloading functions within packages
- Understand the difference between package-level and local variables
- Study forward declarations and when they're required
- Learn initialization blocks and package state management
Understand Trigger Mechanics
- Create examples of all trigger types (BEFORE, AFTER, INSTEAD OF)
- Practice using :NEW and :OLD in row-level triggers
- Understand when to use statement-level vs row-level triggers
- Learn compound triggers and their five timing points
- Study mutating table errors and how to avoid or resolve them
Data Dictionary Views
- Learn to query USER_SOURCE, USER_PROCEDURES, USER_TRIGGERS
- Practice finding object definitions and dependencies
- Understand USER_ERRORS for compilation issues
- Know how to query package specifications vs bodies
- Familiarize with ALL_* and DBA_* view variants
Performance and Best Practices
- Understand when to use bulk operations (FORALL, BULK COLLECT)
- Learn the performance implications of different cursor types
- Study autonomous transactions and when to use PRAGMA
- Know the differences between static and dynamic SQL
- Practice using bind variables vs literals in dynamic SQL
Exam-Specific Strategies
- Practice reading code snippets quickly—many questions include code blocks
- Time yourself: 78 questions in 120 minutes = 92 seconds per question
- Mark difficult questions for review and move on
- Eliminate obviously wrong answers first in multiple choice
- Watch for tricky syntax errors in code examples
- Don't assume code works—look for compilation or runtime errors
Exam Day Tips
- 1Arrive 15-30 minutes early to the testing center or log in early for online proctoring
- 2Bring valid government-issued ID matching your Oracle registration name
- 3Read each question carefully—look for keywords like 'NOT', 'EXCEPT', 'ALWAYS', 'NEVER'
- 4For code questions, trace through execution mentally or use scratch paper
- 5Watch for semicolon placement and syntax errors in code snippets
- 6Remember that some questions may have multiple correct answers—read carefully
- 7Use the mark-for-review feature for questions you're uncertain about
- 8Manage your time: aim to complete 40 questions in first hour, 38 in second hour
- 9If stuck, eliminate wrong answers and make educated guess—no penalty for wrong answers
- 10Review marked questions if time permits at the end
- 11Trust your preparation—your first instinct is often correct
- 12Pay attention to PL/SQL block structure in code examples—missing END or exception handlers
- 13For cursor questions, verify that OPEN, FETCH, and CLOSE are in correct order
- 14Check parameter modes carefully when analyzing procedure/function calls
- 15Remember that predefined exceptions don't need declaration, but user-defined do
