/**
 * A table of data representing a database result set, which
 * is usually generated by executing a statement that queries the database.
 *
 * 
A ResultSet object  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, and because it returns false
 * when there are no more rows in the ResultSet object,
 * it can be used in a while loop to iterate through
 * the result set.
 * 

 * A default ResultSet 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 ResultSet objects that are scrollable and/or
 * updatable.  The following code fragment, in which con
 * is a valid Connection object, illustrates how to make
 * a result set that is scrollable and insensitive to updates by others, and
 * that is updatable. See ResultSet fields for other
 * options.
 * 
 *
 *       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
 *
 * 
 * The ResultSet interface provides
 * getter methods (getBoolean, getLong, 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.
 *
 * 
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 ResultSet getter methods.
 * 

 * 
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 AS clause.
 * 

 * A set of updater methods were added to this interface
 * in the JDBC 2.0 API (JavaTM 2 SDK,
 * Standard Edition, version 1.2). The comments regarding parameters
 * to the getter methods also apply to parameters to the
 * updater methods.
 *

 * The updater methods may be used in two ways:
 * 

 * 
to update a column value in the current row.  In a scrollable
 *     ResultSet 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 NAME column
 *     in the fifth row of the ResultSet object
 *     rs and then uses the method updateRow
 *     to update the data source table from which rs was derived.
 * 
 *
 *       rs.absolute(5); // moves the cursor to the fifth row of rs
 *       rs.updateString("NAME", "AINSWORTH"); // updates the
 *          // NAME column of row 5 to be AINSWORTH
 *       rs.updateRow(); // updates the row in the data source
 *
 * 
 * 
to insert column values into the insert row.  An updatable
 *     ResultSet 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 rs and into
 *     the data source table using the method insertRow.
 * 
 *
 *       rs.moveToInsertRow(); // moves cursor to the insert row
 *       rs.updateString(1, "AINSWORTH"); // updates the
 *          // first column of the insert row to be AINSWORTH
 *       rs.updateInt(2,35); // updates the second column to be 35
 *       rs.updateBoolean(3, true); // updates the third column to true
 *       rs.insertRow();
 *       rs.moveToCurrentRow();
 *
 * 
 * 
 * 
A ResultSet object is automatically closed when the
 * Statement object that
 * generated it is closed, re-executed, or used
 * to retrieve the next result from a sequence of multiple results.
 *
 * 
The number, types and properties of a ResultSet
 * object's columns are provided by the ResulSetMetaData
 * object returned by the ResultSet.getMetaData method.
 *
 * @see Statement#executeQuery
 * @see Statement#getResultSet
 * @see ResultSetMetaData
