Jag stötte på ett liknande problem på grund av att infoga parenteser runt data :-(:
INSERT INTO Customers (Name,LastCredit,CreditDate) VALUES ( <-- Here.
("Nuclear Millitary Systems",500.0,CURRENT_DATE),
("Evil Corporation",67890.95,"2012-02-12"),
("Nuke Software Systems",5600.0,"2013-05-06"),
("RR Millitary",600.0,"2013-05-06"),
("Random Automation",560.0,"2012-05-01"),
("Evil Data Systems",600.0,"2013-03-01")
);
