  /**
   * A table of data representing a database result set, which
   * is usually generated by executing a statement that queries the database.
   *
   * <P>A <code>ResultSet</code> object  maintains a cursor pointing
   * to its current row of data.  Initially the cursor is positioned
   * before the first row. The <code>next</code> method moves the
   * cursor to the next row, and because it returns <code>false</code>
   * when there are no more rows in the <code>ResultSet</code> object,
   * it can be used in a <code>while</code> loop to iterate through
   * the result set.
   * <P>
   * A default <code>ResultSet</code> object is not updatable and
   * has a cursor that moves forward only.  Thus, you can
   * iterate through it only once and only from the first row to the
   * last row. It is possible to
   * produce <code>ResultSet</code> objects that are scrollable and/or
   * updatable.  The following code fragment, in which <code>con</code>
   * is a valid <code>Connection</code> object, illustrates how to make
   * a result set that is scrollable and insensitive to updates by others, and
   * that is updatable. See <code>ResultSet</code> fields for other
   * options.
   * <PRE>
   *
   *       Statement stmt = con.createStatement(
   *                                      ResultSet.TYPE_SCROLL_INSENSITIVE,
   *                                      ResultSet.CONCUR_UPDATABLE);
   *       ResultSet rs = stmt.executeQuery("SELECT a, b FROM TABLE2");
   *       // rs will be scrollable, will not show changes made by others,
   *       // and will be updatable
   *
   * </PRE>
   * The <code>ResultSet</code> interface provides
   * <i>getter</i> methods (<code>getBoolean</code>, <code>getLong</code>, and so on)
   * for retrieving column values from the current row.
   * Values can be retrieved using either the index number of the
   * column or the name of the column.  In general, using the
   * column index will be more efficient.  Columns are numbered from 1.
   * For maximum portability, result set columns within each row should be
   * read in left-to-right order, and each column should be read only once.
   *
   * <P>For the getter methods, a JDBC driver attempts
   * to convert the underlying data to the Java type specified in the
   * getter method and returns a suitable Java value.  The JDBC specification
   * has a table showing the allowable mappings from SQL types to Java types
   * that can be used by the <code>ResultSet</code> getter methods.
   * <P>
   * <P>Column names used as input to getter methods are case
   * insensitive.  When a getter method is called  with
   * a column name and several columns have the same name,
   * the value of the first matching column will be returned.
   * The column name option is
   * designed to be used when column names are used in the SQL
   * query that generated the result set.
   * For columns that are NOT explicitly named in the query, it
   * is best to use column numbers. If column names are used, the
   * programmer should take care to guarantee that they uniquely refer to
   * the intended columns, which can be assured with the SQL <i>AS</i> clause.
   * <P>
   * A set of updater methods were added to this interface
   * in the JDBC 2.0 API (Java<sup><font size=-2>TM</font></sup> 2 SDK,
   * Standard Edition, version 1.2). The comments regarding parameters
   * to the getter methods also apply to parameters to the
   * updater methods.
   *<P>
   * The updater methods may be used in two ways:
   * <ol>
   * <LI>to update a column value in the current row.  In a scrollable
   *     <code>ResultSet</code> object, the cursor can be moved backwards
   *     and forwards, to an absolute position, or to a position
   *     relative to the current row.
   *     The following code fragment updates the <code>NAME</code> column
   *     in the fifth row of the <code>ResultSet</code> object
   *     <code>rs</code> and then uses the method <code>updateRow</code>
   *     to update the data source table from which <code>rs</code> was derived.
   * <PRE>
   *
   *       rs.absolute(5); // moves the cursor to the fifth row of rs
   *       rs.updateString("NAME", "AINSWORTH"); // updates the
   *          // <code>NAME</code> column of row 5 to be <code>AINSWORTH</code>
   *       rs.updateRow(); // updates the row in the data source
   *
   * </PRE>
   * <LI>to insert column values into the insert row.  An updatable
   *     <code>ResultSet</code> object has a special row associated with
   *     it that serves as a staging area for building a row to be inserted.
   *     The following code fragment moves the cursor to the insert row, builds
   *     a three-column row, and inserts it into <code>rs</code> and into
   *     the data source table using the method <code>insertRow</code>.
   * <PRE>
   *
   *       rs.moveToInsertRow(); // moves cursor to the insert row
   *       rs.updateString(1, "AINSWORTH"); // updates the
   *          // first column of the insert row to be <code>AINSWORTH</code>
   *       rs.updateInt(2,35); // updates the second column to be <code>35</code>
   *       rs.updateBoolean(3, true); // updates the third column to <code>true</code>
   *       rs.insertRow();
   *       rs.moveToCurrentRow();
   *
   * </PRE>
   * </ol>
   * <P>A <code>ResultSet</code> object is automatically closed when the
   * <code>Statement</code> object that
   * generated it is closed, re-executed, or used
   * to retrieve the next result from a sequence of multiple results.
   *
   * <P>The number, types and properties of a <code>ResultSet</code>
   * object's columns are provided by the <code>ResultSetMetaData</code>
   * object returned by the <code>ResultSet.getMetaData</code> method.
   *
   * @see Statement#executeQuery
   * @see Statement#getResultSet
   * @see ResultSetMetaData
