What does the ISMATCH function allow you to do with strings in queries?

The ISMATCH function is essential for performing pattern matching in strings, which often involves using regular expressions. This capability allows users to check if a given string matches a specific pattern or follows certain criteria set by the regular expression syntax. Regular expressions are powerful tools for string manipulation, enabling a wide array of comparisons by defining complex search patterns.

In the context of queries, being able to utilize regular expressions via the ISMATCH function opens up possibilities for validating user inputs, filtering data, or making decisions based on string formats, such as validating email addresses or checking for specific substrings. This ability to use regular expressions makes ISMATCH a versatile function in querying string data.
