Using Native Queries
JPQL is a very powerful mechanism to access relational databases with an abstraction of the underlying database. Native Queries refers to executing SQL statements directly against the database. Depending on your requirements you might consider using Native queries, for instances like:
- Executing complex SQL operations that are not easily expressible in JPQL, for instance, queries that involve subqueries or database-specific functions.
- When you need to fine-tune the performance of a query, leveraging database-specific optimizations, indexes, and hints to improve the query execution time.
- Database-specific features, for instance, the databases that can manage JSON structures, may have different ways of doing it.
- Bulk Operations: Native queries are often more efficient for executing bulk insert, update, or delete operations on a large number of records, as they bypass the overhead of entity management and caching that comes with JPQL.
