SQL Essentials: OR Operator in CASE Explained

Overview

The OR operator is a logical operator used in CASE WHEN statements to evaluate multiple conditions and return a result based on the first condition that evaluates to true. It allows you to create flexible and dynamic queries by providing an alternative option when the initial condition is not met.

In simple terms, the OR operator is like having a decision-making checklist. You present the database with multiple options or conditions, and it checks each one until it finds one that is true. Once it finds a true condition, it performs the corresponding action or returns the associated result.
