<p>
Sometimes, the actual database data type does not match the SQL data type that you would like to use in Java. This is often the case for ill-supported SQL data types, such as <code>BOOLEAN</code> or <code>UUID</code>. jOOQ's code generator allows you to apply simple data type rewriting. The following configuration will rewrite <code>IS_VALID</code> columns in all tables to be of type <code>BOOLEAN</code>.

See the section about <reference id="custom-data-types" title="Custom data types"/> for rewriting columns to your own custom data types.
