OCS to OJS data export

Postby johnkperks » Wed Jun 13, 2012 4:43 pm


We have a database of 300 delegates in OCS. Recently, we try to export that OCS database of users to OJS and keep on getting error "OJS DB Error: Column 'last_name' cannot be null". Can someone help please?

Hi johnkperks,

Are you doing a direct database conversion (i.e. right from your OCS MySQL to your OJS MySQL)?

The message suggests that you're trying to insert a value into the users table without supplying a value for the last_name column, which requires a value.
