Interface ResultSetInternalMethods

All Superinterfaces:
  java.sql.ResultSet, java.sql.Wrapper

All Known Implementing Classes:
  JDBC4ResultSet, JDBC4UpdatableResultSet, ResultSetImpl, UpdatableResultSet

    public interface ResultSetInternalMethods

extends java.sql.ResultSet

This interface is intended to be used by implementors of statement interceptors so that implementors can create static or dynamic (via java.lang.reflect.Proxy) proxy instances of ResultSets. It consists of methods outside of java.sql.Result that are used internally by other classes in the driver. This interface, although public is not designed to be consumed publicly other than for the statement interceptor use case.

### getObjectStoredProc

    java.lang.Object getObjectStoredProc(int columnIndex,
                                         int desiredSqlType)
                                         throws java.sql.SQLException
