I’m trying to update from Expression Engine 2.5.5 to 2.10.1 and I get this error:

A Database Error Occurred Error Number: 1048

Column ‘field_id_14’ cannot be null

UPDATE exp_channel_data SET field_id_14 = NULL

Filename: D:\EE_directory\system\codeigniter\system\database\DB_driver.php

Line Number: 382

Have you identified which field is id 14?

You can by looking at table exp_field-types or by looking at your field-groups inside the CP. Once you figure out the field in question, that may give you a clue. If unused, you can try getting rid of it.

Or you can change the NULLs to "" by running the following Query (backup your table before doing this, just in case):

UPDATE exp_channel_data SET field_id_14 = "" WHERE field_id_14 = NULL.
  • exp_fieldtypes only goes up to 10, so I don't think I know what I'm looking for. I looked at exp_channel_data -> field_id_14 values in the db and none are set to NULL. I ran the command anyway and 0 rows were affected. thx Commented Oct 26, 2015 at 19:40
  • Actually, you should take a look in exp_channel_fields to identify which one has field_id 14. If you don't need it, I recommend removing it. I'm not sure what happens if you delete its record from that table, so I'd delete it from your EE Control Panel (Admin > Channel Admin > Channel Fields).

  • In the table exp_channel_fields, looking in field_id, the entry with an ID of 14 shows field_name is 'information_category'. Numbers shown at Admin > Channel Admin > Channel Fields page only goes up to 10 and I don't see how the Channel Fields info presented on this Admin page relates to the exp_channel_fields table. I may not know what I'm looking for. Commented Oct 27, 2015 at 23:18
