In MySQL storage time, we can use the DateTime format, timestamp format, can also be used in int format. So what should we think about when we design?First of all, I think we should understand how these formats are, and then look at their differences so that we can think about when to use the right format.The datetime format, by default, is "Yyyy-mm-dd HH:MM:SS", which represents 19 characters from 1000-01-

In the previous collection script, the collection time is taken out in the form of unix timestamps. When writing SQL statements, you need to query the corresponding records by time, the $ time passed in on the page is a string like '2017-01'. How can I write an SQL statement? $ SQL. = and \ ''. $ time. '\''; this way, records corresponding to $ time in the database can be retrieved. Some may say why don't we directly strtotime () $ time and then match the database data? The situation is as f

DateTime types are used when you need to include values for both date and time information. MySQL retrieves and displays the datetime value in the ' yyyy-mm-dd HH:MM:SS ' format, supported by ' 1000-01-01 00:00:00 ' to ' 9999-12-31 23:59:59 '. ("support" means that although earlier values may work, there is no guarantee that they can.) ） The date type has no time part when you only need a date value. MySQL
