Unsigned types

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

The JDBC and Java type system don't know any unsigned integer data types, but some databases do, most importantly MySQL. This flag allows for overriding the default mapping from unsigned to signed integers and generates jOOU types instead:

Those types work just like ordinary java.lang.Number wrapper types, except that there is no primitive version of them. The configuration looks like follows:

XML (standalone and maven)
Programmatic
Gradle
<configuration>
  <generator>
    <database>
      <unsignedTypes>true</unsignedTypes>
    </database>
  </generator>
</configuration>

See the configuration XSD, standalone code generation, and maven code generation for more details.

new org.jooq.meta.jaxb.Configuration()
  .withGenerator(new Generator()
    .withDatabase(new Database()
      .withUnsignedTypes(true)
    )
  )

See the configuration XSD andprogrammatic code generation for more details.

myConfigurationName(sourceSets.main) {
  generator {
    database {
      unsignedTypes = true
    }
  }
}

See the configuration XSD andgradle code generation for more details.
