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
UUID. jOOQ's code generator allows you to apply simple data type rewriting. The following configuration will rewrite
IS_VALID columns in all tables to be of type
<database> <!-- Associate data type rewrites with database columns --> <forcedTypes> <forcedType> <!-- Specify any data type that is supported in your database, or if unsupported, a type from org.jooq.impl.SQLDataType --> <name>BOOLEAN</name> <!-- Add a Java regular expression matching fully-qualified columns. Use the pipe to separate several expressions. If provided, both "expressions" and "types" must match. --> <expressions>.*\.IS_VALID</expressions> <!-- Add a Java regular expression matching data types to be forced to have this type. If provided, both "expressions" and "types" must match. --> <types>.*</types> </forcedType> </forcedTypes> </database>
You must provide at least either an
<expressions/> or a
<types/> element, or both.
See the section about Custom data types for rewriting columns to your own custom data types.
