 public ResultSet getResultSet() throws SQLException

<dl>
  <dd> Implements Array interface method
Returns a result set that contains the elements of the array
designated by this <code>Array</code> object.  If appropriate,
the elements of the array are mapped using the connection's type
map; otherwise, the standard mapping is used.
<p>
The result set contains one row for each array element, with
two columns in each row.  The second column stores the element
value; the first column stores the index into the array for
that element (with the first array element being at index 1).
The rows are in ascending order corresponding to
the order of the indices.
<p>
  <dd><dl>
    <dt> <b>Returns:</b>
    <dd> a {@link ResultSet} object containing one row for each
of the elements in the array designated by this <code>Array</code>
object, with the rows in ascending order based on the indices.
    <dt> <b>Throws:</b> SQLException
    <dd> if an error occurs while attempting to
access the array

 public ResultSet getResultSet(Dictionary map) throws SQLException
</pre>
<dl>
  <dd> Implements Array interface method   
Returns a result set that contains the elements of the array
designated by this <code>Array</code> object and uses the given
<code>map</code> to map the array elements.  If the base
type of the array does not match a user-defined type in
<code>map</code>, the standard mapping is used instead.
<p>
The result set contains one row for each array element, with
two columns in each row.  The second column stores the element
value; the first column stores the index into the array for
that element (with the first array element being at index 1).
The rows are in ascending order corresponding to
the order of the indices.

  <dd><dl>
    <dt> <b>Parameters:</b>
    <dd> map - contains mapping of SQL user-defined types to
classes in the Java(tm) programming language

    <dd> a <code>ResultSet</code> object containing one row for each
of the elements in the array designated by this <code>Array</code>
object, with the rows in ascending order based on the indices.

</pre>
<dl>
  <dd> Implements Array interface method   
Returns a result set holding the elements of the subarray that
starts at index <code>index</code> and contains up to
<code>count</code> 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.
<P>
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 <code>index</code>.  The result set has
up to <code>count</code> rows in ascending order based on the
indices.  Each row has two columns:  The second column stores
the element value; the first column stroes the index into the
array for that element.
<p>
  <dd><dl>
    <dt> <b>Parameters:</b>
    <dd> index - the array index of the first element to retrieve;
the first element is at index 1
    <dd> count - the number of successive SQL array elements to retrieve
    <dt> <b>Returns:</b>
    <dd> a <code>ResultSet</code> object containing up to
<code>count</code> consecutive elements of the SQL array
designated by this <code>Array</code> object, starting at
index <code>index</code>.

<dl>
  <dd> Implements Array interface method   
Returns a result set holding the elements of the subarray that
starts at index <code>index</code> and contains up to
<code>count</code> successive elements.  This method uses
the <code>Map</code> object <code>map</code> to map the elements
of the array unless the base type of the array does not match
a user-defined type in <code>map</code>, in which case it uses
the standard mapping.
<P>
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 <code>index</code>.  The result set has
up to <code>count</code> rows in ascending order based on the
indices.  Each row has two columns:  The second column stores
the element value; the first column stroes the index into the
array for that element.

of SQL type names to classes in the Java(tm) programming language
    <dt> <b>Returns:</b>
    <dd> a <code>ResultSet</code> object containing up to
<code>count</code> consecutive elements of the SQL array
designated by this <code>Array</code> object, starting at
