I've also tried renaming 'Alex' to a temp. value: # update drupal_users set name='Alex_1972' where name='Alex'; UPDATE 1 # INSERT INTO drupal_users (uid, name, mail, created, access) SELECT user_id, username, user_email, user_regdate, user_lastvisit FROM phpbb_users WHERE user_id > 50 and length(username) > 0 and username <> 'Alex'; ERROR: duplicate key value violates unique constraint "drupal_users_name_key" # select username, user_id from phpbb_users where exists (select 1 from drupal_users where drupal_users.name = phpbb_users.username); username | user_id ----------+--------- (0 rows) so there must be a duplicated username in the source table phpbb_users, but how could I find that record?
