NAME

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

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 } );

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

or

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

BACKWARDS COMPATIBILITY

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

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