<h2>MySQL extensions</h2>
Besides the basic functionality
provided by all drivers (see manual),
the MySQL driver also offers these extra features:
<ul>
<li> <b><tt>env:connect(sourcename[,username[,password[,hostname[,port]]]])</tt></b> <br>
In the MySQL driver, this method has two other optional parameters
that indicate the hostname and port to connect.

This additional method returns the number of rows in the query result.<br>
See also: <a href="#cursor_object">cursor objects</a>
</ul>
Note: This driver is compatible to version 4.1 of MySQL API,
with support to BDB and INNODB tables.
MySQL has types of tables that don't support transactions,
so with these types, the methods <tt>setautocommit</tt>, <tt>commit</tt>
and <tt>rollback</tt> don't work.
