Hibernate Criteria API vs HQL: Which Should I Use?

What are the main differences between Hibernate Criteria API and HQL?

Hibernate Criteria API is a programmatic way to create queries, while HQL is a query language similar to SQL. Criteria API is more flexible and type-safe, whereas HQL is more concise and easier for simple queries.

When should I use Criteria API instead of HQL?

You should use Criteria API when you need dynamic queries or want to build queries programmatically. It's also beneficial for complex queries involving multiple criteria.

Are there performance differences between the two?

Generally, performance is similar, but Criteria API can be less efficient for very complex queries due to its abstraction. HQL might perform better in straightforward cases.

Can I use both in the same project?

Yes, you can use both Hibernate Criteria API and HQL in the same project. Choose based on the specific needs of each query.
