Problem when i try to replace Joomla database in phpMyAdmin


I try to install the new Drupal version of my customer website who was on joomla until now. But i have a database problem.
Although I empty the joomla database and import the drupal one in phpMyAdmin, I have this error message when I’m trying to connect to the site: Table ‘mydatabase.jnew_session’ doesn’t exist SQL=INSERT INTO `jnew_session` (`session_id`, `client_id`, `time`) VALUES (‘c47le3pqi8pp9kfq32anejhu90’, 0, ‘1520079798’)

Hoping that someone can help me,
thanks a lot in advance,

Drupal version:
