What are the differences between Hibernate Criteria and JPQL?

Hibernate Criteria is a programmatic way to create queries using Java objects, while JPQL (Java Persistence Query Language) is a string-based query language similar to SQL.

Can you give me an example of each?

Sure! For Criteria, you might use CriteriaBuilder to create a query, while in JPQL, you would write something like SELECT e FROM Employee e WHERE e.salary > 50000.

Which one is better for performance?

It depends on the use case. Criteria can be more efficient for dynamic queries, while JPQL is often easier to read and write for static queries.

Are there any limitations to using Criteria?

Yes, Criteria API can be more verbose and complex for simple queries compared to JPQL, which is more straightforward.
