An expression to be used exclusively in GROUP BY clauses.

The SELECT … GROUP BY clause accepts a variety of expressions, mostly ordinary Field expressions, but also some special expressions usable only in the GROUP BY clause, such as DSL.groupingSets(Field[][]).

Example: 


 // Assuming import static org.jooq.impl.DSL.*;

 using(configuration)
    .select(ACTOR.LAST_NAME)
    .from(ACTOR)
    .groupBy(ACTOR.LAST_NAME) // GroupField reference here
    .fetch();

Instances can be created using DSL.groupingSets(Field[][]) and related methods, or by creating a subtype.
