Does SQL contain a certain character?

In SQL, the LIKE operator can be used to determine if a string contains a particular character or sequence of characters. The LIKE operator is typically used in conjunction with wildcards, with % representing any character wildcard.

Here is an example query to check if the “first_name” column in a table named “employees” contains the character “a”:

SELECT * FROM employees WHERE first_name LIKE '%a%';

This query will return all the records in the “first_name” column that contain the character “a”.
