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.
