Java, SQL and jOOQ. Best Practices and Lessons Learned from Writing Awesome Java and SQL Code. Get some hands-on insight on what’s behind developing jOOQ.
- Consider using JSON arrays instead of JSON objects for serialisationby lukaseder on August 11, 2025 at 12:43 pm
When implementing the awesome MULTISET operator in jOOQ, its implementation mostly relied on SQL/JSON support of various RDBMS. In short, while standard SQL supports nested collections via ARRAY or MULTISET operators like this: This is poorly supported in most RDBMS, so jOOQ emulates it using […]
- When SQL Meets Lambda Expressionsby lukaseder on March 27, 2025 at 1:04 pm
ARRAY types are a part of the ISO/IEC 9075 SQL standard. The standard specifies how to: But it is very unopinionated when it comes to function support. The ISO/IEC 9075-2:2023(E) 6.47 <array value expression> specifies concatenation of arrays, whereas the 6.48 <array value function> […]
- Think About SQL MERGE in Terms of a RIGHT JOINby lukaseder on March 13, 2025 at 2:45 pm
RIGHT JOIN is an esoteric feature in the SQL language, and hardly ever seen in the real world, because almost every RIGHT JOIN can just be expressed as an equivalent LEFT JOIN. The following two statements are equivalent: It’s not unreasonable to expect these two statements to produce the same […]
- Resisting the Urge to Document Everything Everywhereby lukaseder on February 28, 2025 at 10:39 am
Every product manager knows this situation: This is such a common pattern, and while it’s perfectly understandable for such a user to request this, it is so terribly wrong to give in to this user’s request. Why is it wrong? The features are unrelated Most of the time, the two features X1 and X2 […]
- jOOQ 3.20 released with ClickHouse, Databricks, and much more DuckDB support, new modules, Oracle type hierarchies, more spatial support, decfloat and synonym support, hidden columns, Scala 3, Kotlin 2, and much moreby lukaseder on February 20, 2025 at 10:27 am
New dialects: jOOQ 3.20 ships with 2 new experimental dialects: ClickHouse is a fast-moving SQL dialect with a historic vendor-specific syntax that is gradually migrated to a more standards compliant alternative, which is why our support is still experimental. A lot of behaviours differ from what […]
