------解决方案--------------------
直接return一个空字符串,这样用起来也不用判断直接连字符串。
return "";
------解决方案--------------------
首先你数据库里面的那条或者那些数据的时间字段是int(10) 吗 如果是的化 假如这个字段的名称叫
time 那么 你搜索数据的时候
select * from tbl_name where time
select * from tbl_name where unix_timestamp(time) 转化的方法:
select unix_timestamp("2011-11-22 18:55:05");
这样就可以了 最好抽点时间学习点mysql的函数 这些可以节省很多时间

1. Overview As part of this article, let us start with some problems with the existing Date and CalendarAPI and explore how the new Java8Date and TimeAPI solve these problems. We will also take a look at the core classes in the Java8 time class library, such as LocalDate, LocalTime, LocalDateTime, ZonedDateTime, Period, Duration and their APIs. 2. The problem of thread safety of the old time API (before Java 8)-Date and Calendar classes are not thread-safe, making it difficult for developers to debug concurrency problems of these APIs and need to write additional code to deal with them.
