PL/SQL Recipes

PL/SQL

Recipes for writing robust PL/SQL code — exception handling, bulk operations, cursors, packages, and common patterns.

Handle errors gracefully with predefined exceptions, custom exceptions, and SQLCODE/SQLERRM.

Process large datasets efficiently by fetching and modifying rows in bulk instead of one at a time.

Understand when to use explicit cursors, implicit cursors, and cursor FOR loops.

Run independent transactions for logging and auditing without affecting the main transaction.

Work with associative arrays, nested tables, and PL/SQL records for complex data structures.

Return result sets from PL/SQL functions that can be queried like tables.
