/**
 * <P>A ResultSet provides access to a table of data generated by
 * executing a Statement. The table rows are retrieved in
 * sequence. Within a row its column values can be accessed in any
 * order.
 * 
 * <P>A ResultSet maintains a cursor pointing to its current row of
 * data.  Initially the cursor is positioned before the first row.
 * The 'next' method moves the cursor to the next row.
 *
 * <P>The getXXX methods retrieve column values for the current
 * row.  You can retrieve values either using the index number of the
 * column, or by using the name of the column.  In general using the 
 * column index will be more efficient.  Columns are numbered from 1.
 *
 * <P>For maximum portability, ResultSet columns within each row should be
 * read in left-to-right order and each column should be read only once.
 *
 * <P>For the getXXX methods, the JDBC driver attempts to convert the
 * underlying data to the specified Java type and returns a suitable
 * Java value.  See the JDBC specification for allowable mappings
 * from SQL types to Java types with the ResultSet.getXXX methods.
 *
 * <P>Column names used as input to getXXX methods are case
 * insensitive.  When performing a getXXX using a column name, if
 * several columns have the same name, then 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. For columns that are NOT explicitly named in the query, it
 * is best to use column numbers. If column names were used there is
 * no way for the programmer to guarantee that they actually refer to
 * the intended columns.
 *
 * <P>A ResultSet is automatically closed by the Statement that
 * generated it when that Statement is closed, re-executed, or is used
 * to retrieve the next result from a sequence of multiple results.
 * 
 * <P>The number, types and properties of a ResultSet's columns are
 * provided by the ResulSetMetaData object returned by the getMetaData
 * method.

 * @see Statement#getResultSet
