Question

well i have this messages table with sample values like these:

msg_id  recipient_id   read   locked   new   0         1            N       Y      Y   2         1            Y       N      N 

ok, so lets just say this is a messaging table, and i want to reset all messages addressed to recipient with id=1

i was wondering why

UPDATE `messages` SET `new`='Y',`read`='N',`locked`='N' where `recipient_id`=1; 

doesn’t work, MYSQL always returns 0 affected rows… can anyone help me?

to robert gamble: yes, im sure the values were changed, since my purpose for this update query is to reset the data i was using for the testing phases 😀

Answer 1

You have some floating single-quotes in there. You may be assigning one string to another or something.

It’s ok to just say

UPDATE messages   SET new = 'y', read = 'N', locked = 'N'   WHERE recipient_id = 1
