Previously on this blog, I've written a post explaining why you should use jOOQ's code generator, despite the possibility of using jOOQ without it. In a similar fashion, as I've answered numerous jOOQ questions on Stack Overflow, where someone used jOOQ to build a query, but then executed it elsewhere, including on: JPA JDBC / … Continue reading Why You Should Execute jOOQ Queries With jOOQ

jOOQ’s R2DBC LoggingConnection to log all SQL statements
jOOQ already has a LoggingConnection (see also the manual), which acts as a JDBC proxy Connection to log all SQL statements that are executed by any JDBC client (including Hibernate, MyBatis, JdbcTemplate, native JDBC, etc.). Starting from jOOQ 3.18.0, 3.17.7, and 3.16.13, a LoggingConnection is now also available for R2DBC clients to log all reactive … Continue reading jOOQ’s R2DBC LoggingConnection to log all SQL statements

The Many Different Ways to Fetch Data in jOOQ
The jOOQ API is all about convenience, and as such, an important operation (the most important one?) like fetch() must come with convenience, too. The default way to fetch data is this: Result<Record1<String>> result = ctx.select(BOOK.TITLE) .from(BOOK) .fetch(); for (Record1<String> record : result) { // ... } It fetches the entire result set into memory … Continue reading The Many Different Ways to Fetch Data in jOOQ
Nested Transactions in jOOQ
Since jOOQ 3.4, we have an API that simplifies transactional logic on top of JDBC in jOOQ, and starting from jOOQ 3.17 and #13502, an equivalent API will also be made available on top of R2DBC, for reactive applications. As with everything jOOQ, transactions are implemented using explicit, API based logic. The implicit logic implemented … Continue reading Nested Transactions in jOOQ
Detect Accidental Blocking Calls when Using R2DBC
A while ago, jOOQ has added the org.jetbrains:annotations dependency to the jOOQ API, in order to annotate return types with nullability information. For example, the entire DSL is non-nullable: public interface SelectWhereStep<R extends Record> extends SelectConnectByStep<R> { @NotNull @CheckReturnValue @Support SelectConditionStep<R> where(Condition condition); // ... } It makes sense to give this guarantee especially to … Continue reading Detect Accidental Blocking Calls when Using R2DBC
Reactive SQL with jOOQ 3.15 and R2DBC
One of the biggest new features of the recently released jOOQ 3.15 is its new support for reactive querying via R2DBC. This has been a highly popular feature request, and we finally delivered on it. You can continue using jOOQ the way you were used to, providing you with type safe, embedded SQL in Java, … Continue reading Reactive SQL with jOOQ 3.15 and R2DBC
3.15.0 Release with Support for R2DBC, Nested ROW, ARRAY, and MULTISET types, 5 new SQL dialects, CREATE PROCEDURE, FUNCTION, and TRIGGER support and Much More
R2DBC What a lot of users have been waiting for: jOOQ 3.15 is reactive, thanks to the new native R2DBC integration. Recent versions already implemented the reactive streams Publisher SPI, but now we're not cheating anymore. We're not longer blocking. Just wrap your R2DBC ConnectionFactory configured jOOQ query in a Flux (or any reactive streams … Continue reading 3.15.0 Release with Support for R2DBC, Nested ROW, ARRAY, and MULTISET types, 5 new SQL dialects, CREATE PROCEDURE, FUNCTION, and TRIGGER support and Much More
