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

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

DESCRIPTION
    mysql stores session records in a MySQL table. For details see 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
      );

    To use different column names, change the 'create table' statement, and then simply do this:

        $s = CGI::Session->new('driver:mysql', undef,
        {
            TableName=>'session',
            IdColName=>'my_id',
            DataColName=>'my_data',
            DataSource=>'dbi:mysql:project',
        });

    or

        $s = CGI::Session->new('driver:mysql', undef,
        {
            TableName=>'session',
            IdColName=>'my_id',
            DataColName=>'my_data',
            Handle=>$dbh,
        });

  DRIVER ARGUMENTS
    mysql driver supports all the arguments documented in CGI::Session::Driver::DBI. In addition,
    *DataSource* argument can optionally leave leading "dbi:mysql:" string out:

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

  BACKWARDS COMPATIBILITY
    As of V 4.30, the global variable $CGI::Session::MySQL::TABLE_NAME cannot be used to set the
    session table's name.

    This is due to changes in CGI::Session::Driver's new() method, which now allows the table's name
    to be changed (as well as allowing both the 'id' column name and the 'a_session' column name to
    be changed).

    See the documentation for CGI::Session::Driver::DBI for details.

    In particular, the new syntax for "new()" applies to all database drivers, whereas the old - and
    bad - global variable method only applied to MySQL.

    Alternately, call $session -> table_name('new_name') just after creating the session object if
    you wish to change the session table's name.
