applySqlSelections
public void applySqlSelections(DomainResultCreationState creationState)
Description copied from interface:DomainResultProducerUsed when this producer is a selection in a sub-query. The DomainResult is only needed for root query of a SELECT statement. This default impl assumes this producer is a true (Sql)Expression- Specified by:
