jOOQ

jOOQ's DSL validates column names, table references, and data types at compile time, preventing errors like typos and mismatches, as shown in the README's IDE auto-completion screenshots.

Supports complex SQL operations like nested collections with MULTISET and implicit joins, enabling type-safe mapping to DTOs in a single query, demonstrated in the film-actor-category example.

Works with 30+ RDBMS with automatic SQL translation, allowing developers to write database-agnostic code without rewriting queries for different systems.

Enables building SQL queries dynamically while maintaining type safety through the DSL API, useful for conditional logic and adaptive filtering without sacrificing validation.
