n SQL, the "LIKE" keyword is used to search for a specified pattern within a column. It's commonly used in conjunction with the "WHERE" clause to filter rows based on specific text patterns, making it a powerful tool for querying data in databases.
Let's say we have a table named users with a column named username. We want to retrieve all users whose usernames start with the letter "J". We can use the "LIKE" keyword as follows:
SELECT * FROM users
WHERE username LIKE 'J%';
This query will return all rows from the users table where the username column starts with the letter "J". The "%" symbol is a wildcard that matches any sequence of characters.
