Hi all,
I recently encounter the "(1062) Duplicate entry '' for key '*UNKNOWN*'" error with the following SQL. It is strange that none of the updating value is '', and why is the key *UNKNOWN* ???
Please help.
1) (1062) Duplicate entry '' for key '*UNKNOWN*'
UPDATE common_task SET applicants=applicants+'1' WHERE taskid=5
2) (1062) Duplicate entry '' for key '*UNKNOWN*'
UPDATE common_task SET achievers=achievers+'1' WHERE taskid=10
3) (1062) Duplicate entry '' for key '*UNKNOWN*'
INSERT INTO forum_medallog SET `uid`='6042' , `medalid`='36' , `type`='0' , `dateline`='1407142477' , `expiration`='0' , `status`='0'
4) (1062) Duplicate entry '' for key '*UNKNOWN*'
