我在我的问答中有一个问题,我以这种格式在数据库中节省了时间:

我想按日期对各行各业进行分类,但这一日期格式不允许我这样做。 页: 1 日期_FORMAT和STR_TO_DATE功能,但若无工作能力,请帮助我解决这一问题?
假设你修改了表格,以便你能够进入原定日期(新日期),并希望将重新调整的本地日期引入一个新的领域(新日期),然后:
UPDATE yourtable
SET newdate = STR_TO_DATE(olddate, %a, %e %b %Y %H:%i:%s )
然而,MySQL并不在其日期/时间领域储存时间区信息,因此,你必须把厄立特里亚国防军的帽子转化为任何希望的茨克区(UTC?)。
一旦改为本土形式,你将:
SELECT ...
...
ORDER BY YEAR(newdate)
这一格式只是MySQL的明晰文本,你应当有另一个文本,即:datetime或timeamp,有相同的数据,但MySQL可以理解。
