BETWEEN Operator

The BETWEEN operator is a powerful SQL construct used to filter records within a specified range, making it highly useful for queries that require range-based comparisons. This operator is inclusive, meaning that it includes both endpoints of the defined range. For example:

sqlCopy codeSELECT * FROM products WHERE price BETWEEN 100 AND 200;

In this query, all products with prices ranging from 100 to 200, inclusive, will be retrieved. The BETWEEN operator simplifies the syntax needed for range comparisons, thereby enhancing readability and maintainability of SQL queries. It can be particularly beneficial when analyzing numeric or date values. For instance, when assessing sales data over a specific period, using BETWEEN allows analysts to efficiently filter results based on date ranges, improving their ability to derive insights quickly. This operator can be applied in various contexts, such as filtering customer age ranges or product quantities, making it a versatile tool in data querying.
