What is the difference between IN and Exists in Oracle?
Answer Posted / imran
The EXISTS clause is used to check the existence of rows returned by a subquery. It returns TRUE if the subquery returns one or more rows.
The IN clause is used to filter rows based on a list of values or a subquery result set. It checks if a value matches any value in a list or subquery.
