Answer
Complex JOINs can lead to performance issues and maintenance challenges.
Using complex SQL JOINs can significantly slow down query performance, especially in large datasets, due to the increased computational overhead. They can also make the SQL harder to read and maintain. As a result, it is crucial to carefully design the database schema and indexes. In Java, using simple queries with logic in code can sometimes be more efficient. For example, consider whether a query with multiple JOINs can be split into more manageable parts or if database views could simplify the logic.
