我想比较两个日期和时间,我想要所有结果 from tbl where date1 >日期2
I want to compare two dates with time, I want all the results from tbl where date1 > date2
Select * From temp where mydate > '2009-06-29 04:00:44';但它只是比较日期而不是时间.它给了我今天日期的所有结果集
but it is just comparing dates not time. it is giving me all the result set of today's date
'2009-06-29 11:08:57' '2009-06-29 11:14:35' '2009-06-29 11:12:38' '2009-06-29 11:37:48' '2009-06-29 11:52:17' '2009-06-29 12:12:50' '2009-06-29 12:13:38' '2009-06-29 12:19:24' '2009-06-29 12:27:25' '2009-06-29 12:28:49' '2009-06-29 12:35:54' '2009-06-29 12:36:54' '2009-06-29 12:49:57' '2009-06-29 12:58:04' '2009-06-29 04:13:20' '2009-06-29 04:56:19' '2009-06-29 05:00:23' '2009-06-29 05:04:26' '2009-06-29 05:08:17' '2009-06-29 05:26:57' '2009-06-29 05:29:06' '2009-06-29 05:32:11' '2009-06-29 05:52:07'提前致谢!
推荐答案您要作为示例显示的查询是:
The query you want to show as an example is:
SELECT * FROM temp WHERE mydate > '2009-06-29 16:00:44';04:00:00 是凌晨 4 点,所以您显示的所有结果都在之后出现,这是正确的.
04:00:00 is 4AM, so all the results you're displaying come after that, which is correct.
如果您想在下午 4 点之后显示所有内容,则需要在查询中使用正确的 (24hr) 表示法.
If you want to show everything after 4PM, you need to use the correct (24hr) notation in your query.
为了让事情更清楚,试试这个:
To make things a bit clearer, try this:
SELECT mydate, DATE_FORMAT(mydate, '%r') FROM temp;这将显示日期和 12 小时制.
That will show you the date, and its 12hr time.
