Unknown column 'emp' in 'field list'
1.Please check if you are trying to do the insert/update on the table with trigger.
2.If so, we can either rewrite trigger and remove 'field3' column *from insert command or * alter table 't2' and add column 'field3'.
Please refer to UNOBVIOUS "UNKNOWN COLUMN IN 'FIELD LIST'" ERROR.
Best regards,
Mona
