cgi::session::driver::mysql
CGI::Session::Driver::mysql(3) User Contributed Perl Documentation CGI::Session::Driver::mysql(3)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
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.
