Unable to convert MySQL date/time value to System.DateTime

My database have a column named update_link, datetime type, that constants a row with zero value(0000-00-00 00:00:00). Then each times i try to select row i got this.

This's a solution: add "allow zero datetime" to you connection string

String conn = "SERVER=127.0.0.1;DATABASE=MoodleService;UID=root;PASSWORD=123456";allow zero datetim=true;

Hope this helps
