Read Original

This article presents an alternative method for fetching hierarchical Data Transfer Object (DTO) projections in Spring Data JPA, using the jOOQ library. It explains and provides code examples for using jOOQ's MULTISET value constructor and MULTISET_AGG aggregate function to create type-safe, nested DTO structures from a database, promoting compile-time safety and reduced boilerplate code.
