Sessions - Not Working

I'm trying to use sessions in database on v 3.01 and it is not working. I am getting the error

A Database Error Occurred
Error Number: 1064
You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'WHERE `id` = '79a66a6e1e7cb4dcb58794a078629cc5532f2e6b'' at line 2
SELECT `data` WHERE `id` = '79a66a6e1e7cb4dcb58794a078629cc5532f2e6b'
Filename: libraries/Session/drivers/Session_database_driver.php
Line Number: 160

I am using mysqli

at config.php there is description just before session configuration:

sess_save_path: 
....
| For the 'database' driver, it's a table name.
| Please read up the manual for the format with other session drivers.

At the moment you haven't set its name and for that reason there is NO FROM .. in you session DB queries ..


I missed that line in the user guide. Thanks!!!! It works now...
