time comparison

For example, date 1 is 2009-8-1, date 2 is 2009-7-1. Using the Split function to slice, Method 1 The code is as follows Copy Code Method 2 JS Date comparison (YYYY-MM-DD) The code is as follows

If the current time is July 19, 2007 13:56 47 secondsConvert.todatetime ("07/07/19"). CompareTo (DateTime.Now) The value returned at this time is "-1"Result: Convert.todatetime ("07/07/19") represents a time less than DateTime.NowReasonThe time

Simple string comparison results are imprecise.select * from 表明 where times> ‘2088/12/8 10:02:40‘ (x)The conversion function is as follows (the database is varchar):select * from h_hotelcontext where now() between STR_TO_DATE(Start_time,‘%Y-%m-%d %H:

fields in the database 2017-07-11 13:37:51 type is char or varcharTo compare the input with ' 20170625 ', the format is inconsistent and needs to be converted to: YYYYMMDD string1, first to_dateto_date (create_date, ' yyyy-mm-dd,hh24:mi:ss ') format

Web development sometimes need to enter the time in the box (mainly the start time and end time) to compare, online search, found that a lot of is invalid, the following methods by the younger brother Test really effective, hereby share. (Please pay
