ci_session database problem

Hello,
I want to save session data into my database
my database is MySQL:

Code:

CREATE TABLE IF NOT EXISTS `ci_sessions` (
        `id` varchar(40) NOT NULL,
        `ip_address` varchar(45) NOT NULL,
        `timestamp` int(10) unsigned DEFAULT 0 NOT NULL,
        `data` blob NOT NULL,
        PRIMARY KEY (id),
        KEY `ci_sessions_timestamp` (`timestamp`)
);

I have autoload session and database but I get:

Error Number: 1064

Erreur de syntaxe près de 'WHERE `id` = 'deeb1593af2f5d5d311ef6442cfa684736c8e554'' à la ligne 2

SELECT `data` WHERE `id` = 'deeb1593af2f5d5d311ef6442cfa684736c8e554'

Filename: libraries/Session/drivers/Session_database_driver.php

Line Number: 160

I use CI3

Hello,
Check you are using database session driver and your name for the database is 'ci_sessions' (name your are given when you created your table)

PHP Code:

$config['sess_driver'] = 'database';
$config['sess_save_path'] = 'ci_sessions' ; // config.php file

Another thing, perhaps, have you this in your configuration :

PHP Code:

$autoload['drivers'] = array('session');
$autoload['libraries'] = array('database',...) ; 


Can you show your configuration or the portion of code that causes the error please ?

config.php

PHP Code:

$config['sess_driver'] = 'database';
$config['sess_cookie_name'] = 'ci_sessions';
$config['sess_expiration'] = 7200;
$config['sess_save_path'] = NULL;
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE; 


autoload.php

PHP Code:

$autoload['libraries'] = array(
    'database',
    'session',
    'form_validation',
    'ion_auth',
    'jdate');
$autoload['drivers'] = array('session');

No, you didn't. Your 'sess_save_path' is NULL.

Thanks,fixed
