  • GitHub repo jOOQ

    jOOQ is the best way to write SQL in Java

    Project mention: Weekly "ask anything" thread | reddit.com/r/PHP | 2021-03-22

    I've been hugely inspired by https://github.com/jOOQ/jOOQ . Even though I am not familiar with JAVA much, but I really liked their way of typed column names and every part of SQL. Similar to them, I also want to be as close to SQL as possible. Because in my experience, using ORMs for long time can reduce your memory about simple SQL syntax's. I am also a fan of DB first approach for ORMs.

    Project mention: What is the Specification Pattern | reddit.com/r/programming | 2021-03-04

    I have written some utility functions for composing Specifications in a nicer and safer way, inspired by how QueryDSL composes Predicates. I created a PR in attempt to merge it directly to Spring Data JPA itself (https://github.com/spring-projects/spring-data-jpa/pull/404), but unfortunately it was rejected because the Spring team plans to majorly rework Specifications in the near future (https://github.com/spring-projects/spring-data-jpa/issues/1943#issuecomment-752504333). Feel free to copy the code in my PR for your own use.
