Final answer:
The 'BETWEEN' operator is used to specify that a data value must be within a range to be included in query results, such as finding values between 1 and 5 in a database.
Step-by-step explanation:
The range comparison operator is used to indicate that a data value must fall within a certain range of values to be included in the query results. In SQL and other query languages, this can be accomplished using the BETWEEN operator, which allows you to specify a lower and upper boundary for the values that you want to include in your results. For example, if you are looking for metric measurements in a database that fall within a specific range, you could use a query like 'SELECT * FROM table WHERE column BETWEEN 1 AND 5'. This means that the query will return all records where the column's value is greater than or equal to 1 and less than or equal to 5, inclusively.
Understanding how to use range operators is essential for effectively querying databases and analyzing data. You can use various comparison operators to fine-tune your data selection such as '>' for greater than, '<' for less than, '>=' for greater than or equal to, and '<=' for less than or equal to contribute to defining ranges.
