Writing a program to check if a number is an "Armstrong Number" (or a "narcissistic number") is a classic programming challenge. It's a great exercise to learn how to manipulate individual digits of a number using loops and math functions.…

Swapping the values of two variables (making a become b and b become a) is one of the most fundamental logic puzzles in programming. In PL/SQL, this is easily accomplished by using a third, temporary variable. This simple guide will…

A "palindrome" is a number (or word) that reads the same backward as it does forward. For example, 121, 535, and 7 are all palindrome numbers. Writing a program to check for this is a great exercise because it combines…

Writing a program to reverse a string (for example, turning "hello" into "olleh") is a classic programming challenge. It's a great way to learn how to use loops and string functions to manipulate data one character at a time. This…

Determining if a number is odd or even is a fundamental programming exercise. In PL/SQL, this is very easy to do and is the perfect way to learn about conditional logic (IF...THEN...ELSE) and the MOD function. This simple guide will…

The Fibonacci series is a famous mathematical sequence where each new number is the sum of the two preceding ones. Writing a program to generate this sequence is a fantastic exercise for learning how to manage and "shift" variable values…

Writing a program to reverse a number (for example, turning 12345 into 54321) is a classic programming challenge. It's a great way to learn how to use loops and basic math functions like MOD and TRUNC to manipulate individual digits.…

A common exercise for learning any new programming language is to print a multiplication table (e.g., the "5 times table"). This is a perfect task for learning how to use loops and print formatted output in PL This simple guide…

Writing a program to determine if a number is prime is a classic programming challenge. It's a great exercise to learn about loops, conditional logic (IF statements), and boolean flags in PL This simple guide will walk you through the…

This is one of the most basic and common programs for beginners to write. It teaches you the fundamental structure of a PL/SQL program, including how to declare variables, assign values, perform a calculation, and print the result. This simple…

A common task for new programmers is to compare several values to find the largest or smallest. In Oracle PL/SQL, you can easily find the greatest of three numbers using conditional logic. This simple guide will show you the basic…

Printing patterns like triangles and pyramids is a classic programming exercise for learning how to use loops. In Oracle, you can do this using PL/SQL (Procedural Language/SQL). This simple guide will show you the basic building blocks and two common…
