How to Fix PSQLException: Operator Does Not Exist: Character Varying = UUID

The PSQLException: Operator Does Not Exist: character varying = uuid error in Spring JPA and PostgreSQL arises from comparing UUID and VARCHAR fields. PostgreSQL requires strict type matching, so it won't automatically convert between them. Solutions include using native queries with explicit casting of the VARCHAR to UUID, ensuring consistent UUID typing in both method signatures and queries, or converting UUIDs to strings in your application code if the database column is VARCHAR. Choosing the right approach depends on your specific application needs.
