As data-driven decisions become increasingly crucial to business success, the ability to extract meaningful insights from vast amounts of data has become a valuable asset for organizations. SQL (Structured Query Language) has emerged as the go-to language for data manipulation and analysis. Among its many strengths, SQL between is a powerful operator that allows developers to query data based on a specified range or interval. In this article, we'll delve into the world of SQL between, exploring its applications, benefits, and best practices to help you master this essential SQL skill.
