=head1 NAME

CGI::Session::Driver::mysql - CGI::Session driver for MySQL database

=head1 SYNOPSIS

    $s = new CGI::Session( "driver:mysql", $sid);
    $s = new CGI::Session( "driver:mysql", $sid, { DataSource  => 'dbi:mysql:test',
                                                   User        => 'sherzodr',
                                                   Password    => 'hello' });
    $s = new CGI::Session( "driver:mysql", $sid, { Handle => $dbh } );

=head1 DESCRIPTION

B<mysql> stores session records in a MySQL table. For details see L<CGI::Session::Driver::DBI|CGI::Session::Driver::DBI>, its parent class.

It's especially important for the MySQL driver that the session ID column be
defined as a primary key, or at least "unique", like this:

 CREATE TABLE sessions (
     id CHAR(32) NOT NULL PRIMARY KEY,
     a_session TEXT NOT NULL
  );

=head2 DRIVER ARGUMENTS

B<mysql> driver supports all the arguments documented in L<CGI::Session::Driver::DBI|CGI::Session::Driver::DBI>. In addition, I<DataSource> argument can optionally leave leading "dbi:mysql:" string out:

    $s = new CGI::Session( "driver:mysql", $sid, {DataSource=>'shopping_cart'});
    # is the same as:
    $s = new CGI::Session( "driver:mysql", $sid, {DataSource=>'dbi:mysql:shopping_cart'});

=head2 BACKWARDS COMPATIBILITY

For backwards compatibility, you can also set the table like this before calling C<new()>. However, it is not recommended because it can cause conflicts in a persistent environment. 

    $CGI::Session::MySQL::TABLE_NAME = 'my_sessions';

=head1 LICENSING

For support and licensing see L<CGI::Session|CGI::Session>.
