Error in auto lodaing of sessions ci_session table

[eluser]Unknown[/eluser]
Hi there I just started using ci and kinda understand just a tiny bit of it's concept, I've enabled the 'sess_use_database' in my config which is intended to recognize my ci_session table in my loaded database, this error appears:


Error Number: 1364

Field 'user_data' doesn't have a default value

INSERT INTO `ci_sessions` (`session_id`, `ip_address`, `user_agent`, `last_activity`) VALUES ('820155fa9bc6059cb16165126644bda0', '127.0.0.1', 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv', 1279170475)


and I can't get a work around with it, can anyone help me? I would really appreciate it thank you very much.

You have made an error in defining the ci_sessions table.

Either define the user_data field so that NULL is allowed, or assign a default value to it (p.e. "").

wow thanks WanWizard I've set the default value of the user_data as "null" and allowed null values in my database and it worked, now I can finally go on with this tutorial:

hopefully I get to absorb the information, and successfully create my first program using CI.

thanks
