EXISTS is a keyword used in SQL to check for the existence of any record in a subquery. It executes faster than the IN operator when searching for a single value in a large table. The IN operator is used to specify multiple values in a WHERE clause, and it requires a complete table scan, which can result in slower query execution times.
