| The jOOQ User Manual. Multiple Pages : Code generation : Advanced generator configuration : Database : Unsigned types | previous : next |
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 configuration (standalone and Maven)
<configuration xmlns="http://www.jooq.org/xsd/jooq-codegen-3.9.2.xsd">
<generator>
<database>
<unsignedTypes>true</unsignedTypes>
</database>
</generator>
</configuration>
Programmatic configuration
configuration
.withGenerator(new Generator(
.withDatabase(new Database()
.withUnsignedTypes(true))));
Gradle configuration
myConfigurationName(sourceSets.main) {
generator {
database {
unsignedTypes = true
}
}
}
