[SOLVED]when the session inserts into table, database will show error.. how to solve?

Check out the second link. Maybe that will help. This is most likely not a CI problem. One way to check is if you have phpmyadmin installed. If yes try to run that query and see if you get the error. If yes then its a db issue. If no then I'm sorry I'm out of ideas.

Thank You.

The second link was useful.

You also get this error when the user_data field is defined as 'NOT NULL' (which is how it is defined in the manual).
This is wrong, because when the session is created, the user_data field is not included in the INSERT query.

I think you have to report this as an issue. Either the manual has to be modified, or the user_data field has to be properly initialized when the session record is created.

I agree with your comment.
