Errore MySql

[Domainer]

Ho eseguito sul databse questa query:

INSERT INTO " . TABLE_PREFIX . "cron (weekday,day,hour,minute,filename,loglevel,active,varname, volatile,product)) VALUES (-1, 10, 0, 'a:1:{i:0;i:0;}', './includes/cron/cronautodelete.php', 1, 'Auto Delete/Move  Thread After  per days')

ma mi viene restituito questo errore:

INSERT INTO " . TABLE_PREFIX . "cron(weekday,

DAY ,
HOUR ,
minute,
filename,
loglevel,
active,
varname,
volatile,
product
)
)
VALUES ( -1, 10, 0, 'a:1:{i:0;i:0;}', './includes/cron/cronautodelete.php', 1, 'Auto Delete/Move Thread After per days'
) Messaggio di MySQL:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '" . TABLE_PREFIX . "cron (weekday,day,hour,minute,filename,loglevel,active, varna' at line 1

Qualcuno ha idea di cosa può essere il problema?
