Description: Range queries are a type of SQL query that allows retrieving data that falls within a specific range of values. This type of query is fundamental in database management, as it facilitates the efficient extraction of relevant information. Range queries are commonly used with operators like BETWEEN and comparisons of greater than or less than, allowing users to specify upper and lower limits for the data they wish to retrieve. For example, they can be used to obtain sales records within a date range or to filter products whose price falls between two specified values. The ability to perform range queries is essential for data analysis, as it enables analysts and developers to gain meaningful insights from large volumes of information. Additionally, these queries are highly optimizable, meaning they can be adjusted to improve performance and speed of data retrieval, especially in large and complex databases. In summary, range queries are a powerful tool in SQL that allows users to effectively interact with data, facilitating informed decision-making based on the retrieved information.
