Class ResultSetMappingQuery

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable
    public class ResultSetMappingQuery
extends ObjectBuildingQuery

    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
