Examples of org.eclipse.persistence.queries.ResultSetMappingQuery

org.eclipse.persistence.queries.ResultSetMappingQuery

Purpose: Concrete class to perform read using raw SQL and the SQLResultSetMapping.

Responsibilities: Execute a selecting raw SQL string. Returns a List of results. Each item in the list will be another list consisting of the expected populated return types in the order they were specified in the SQLResultSetMapping @see SQLResultSetMapping @author Gordon Yorke @since TopLink Java Essentials
