最近遇到两次插入日期类型后，数值为 0000-00-00 00:00:00 的情况，于是查了一下官方文档，找到了原因。

Mysql中我们经常用来存储日期的数据类型有三种：Date、Datetime、Timestamp。

Date数据类型用来存储没有时间的日期。Mysql获取和显示这个类型的格式为“YYYY-MM-DD”。支持的时间范围为“1000-00-00”到“9999-12-31”。

Datetime类型存储既有日期又有时间的数据。存储和显示的格式为 “YYYY-MM-DD HH:MM:SS”。支持的时间范围是“1000-00-00 00:00:00”到“9999-12-31 23:59:59”。

Timestamp类型也是存储既有日期又有时间的数据。存储和显示的格式跟Datetime一样。支持的时间范围是“1970-01-01 00:00:01”到“2038-01-19 03:14:07”。


所有不符合上面所述格式的数据都会被转换为相应类型的0值。（0000-00-00或者0000-00-00 00:00:00）
