Php DB在不同月份的两个日期之间获取数据时给出空结果集

我正在使用php/mysql。当我尝试在两个日期之间获取数据时，一切正常。但当我想在两个月之间获取数据时，例如：2014年1月31日和2014年2月3日，它不工作，并给出空结果集。它的工作周期为一个月

我的问题是：

在reg.id=paynline.stuid上加入paynline，其中paynline.status='success'和paynline.paydate>='“$\u POST['date1']”和paynline.paydate在我看来，最好的解决方案是以日期、日期时间或时间戳格式保存日期。

但在您的情况下，如中所述，您可以在查询中使用和在您的条件下将它们转换为DATETIME：

 StruthtoJoad（左边（Pay-No.PayLoad，PayLoad，PayLo.PayDATE），'%m/%D/%y '）在2010－07－28和'2010－07－29′/P>中，你的<代码> PayDATE < /Case>字段有哪些类型？也许你可以将这个问题简化为一个更简单的情况，以便在选择列表中没有厨房接收器？也请考虑SQL注入
