SQL选择created_at大于日期的行

Question

I am getting very odd results running the following query:

select * from "statuses" where "created_at" > '2015-04-26 02:04:24';

this seems to returning the following dates:

2015-04-26 10:44:04
2015-04-26 12:19:47
2015-04-26 12:20:12

as you can see these are actually below the specified DATE/TIME i entered. I assume that this has something to do with the formatting of the date?

How should my query look to get accurate results?

Answer 1

If you have saved the data in datetime or timestamp then you are getting the correct result, the hour minute and second format is H:i:s ie 24 hours format.

So in the comparison

created_at > '2015-04-26 02:04:24'

2015-04-26 02:04:24 means 2 AM + and the results you are getting are all greater than that

10 AM, 12 PM and so

If you are looking to find greater than 2 PM then you need

created_at > '2015-04-26 14:04:24'

Answer 2

Ok, so thanks to the commenters I have figured out what was going on, I didn't actually think to check the actual time value, but in my PHP script I was converting the timestamp to h:m:s this should have been H:m:s (24hr) and it is now producing the correct results.

Thanks for prompting me to check that, I can miss the simplest things sometimes.
