Oracle REGEXP_LIKE Function Guide

In Oracle, the method for matching regular expressions is by using the REGEXP_LIKE function.

The REGEXP_LIKE function is used to check if a string matches a specified regular expression pattern. It takes three parameters: the string to be checked, the regular expression pattern, and optional flags.

For example, the following query uses the REGEXP_LIKE function to check if a string starts with a letter:

Choose all the records from your table where your column starts with a letter in the alphabet.

This will retrieve all records in your_column column that start with a letter.
