                                        throws java.sql.SQLException
        Retrieves a result set holding the elements of the subarray that starts at index index and contains up to count successive elements. This method uses the connection's type map to map the elements of the array if the map contains an entry for the base type. Otherwise, the standard mapping is used.

        The result set has one row for each element of the SQL array designated by this object, with the first row containing the element at index index. The result set has up to count rows in ascending order based on the indices. Each row has two columns: The second column stores the element value; the first column stores the index into the array for that element.

        Specified by:
        getResultSet in interface java.sql.Array
        Parameters:
        index - the array index of the first element to retrieve; the first element is at index 1
        count - the number of successive SQL array elements to retrieve
        Returns:
        a ResultSet object containing up to count consecutive elements of the SQL array designated by this Array object, starting at index index.
