NNGau,
It works because 'where invoiceid-12217' is true for every invoice except invoice 12217.
To undo it, assuming your server is running a binary log, back up the table in its current state to a safe place, restore the most recent backup of the table, then run mysqlbinlog for that database (-d) and that table (-t) from the timepoint of the backup (-start-datetime=...) to just before your typo (-stop-datetime=...).

Help! I did this query and it updated everything!
update customer_order_history set customerID="123 456 789 0123" where invoiceid-12217;
I typed a '-' rather than an '='.
I haven't did a commit or a rollback saving point. Is there any other way To undo this update??
Thanks.
