查询之间的日期不会返回确切的结果

Question

此查询不会返回jan上的记录，但会返回feb上的记录

SELECT EventAsstCharged,CustomerName,EventID ,EventName,EventExpectedCharges,EventActuallyCharged,EventUserCharged,date_format(EventDate,'%d-%m-%Y') as EventDate ,EventTime 
FROM tblevent 
WHERE Status=1 AND date_format(EventDate,'%d-%m-%Y') between '01-01-2011' AND '20-02-2011' AND EntryUser=2 AND Status=1 
ORDER BY EventID DESC

EventDate是DATE类型

Answer 1

MySQL的日期格式为YYYY-MM-DD。尝试

EventDate between '2011-01-01' AND '2011-20-02'
