/**
* 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>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™ 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
* @since 1.1
