SELECTTIMEDIFF(end_time,start_time)AStime_differenceFROMtable_name; 1. 步骤3:将差值转换为分钟 最后,我们需要将差值转换为分钟,可以使用TIME_TO_SEC()函数将时间值转换为秒,然后再将秒转换为分钟。 SELECTTIME_TO_SEC(TIMEDIFF(end_time,start_time))/60AStime_in_minutesFROMtable_name; 1. 饼状图示例 ...
在MySQL中,要以分钟为单位计算经过的时间,可以使用`TIMEDIFF()`函数和`TIME_TO_SEC()`函数。`TIMEDIFF()`函数用于计算两个时间值之间的差异,而`TIME_TO_S...
MySQL TIMEDIFF函数用于计算两个时间之间的差值,返回一个时间间隔。它只适用于非DATETIME类型的时间。 TIMEDIFF函数的语法如下: TIMEDIFF(time1, time2)...
However, TIMEDIFF returns a Time variable if I am correct... how can I turn that to minutes? ALSO... would this work even with the correct casting to minutes? Because of the "ON UPDATE" method used for the updated_at column, I would imagine the timestamp would just be updated, then...
(expr1,expr2) 时间相减,格式必须相同 TIMEDIFF(expr1,expr2) 时间相减,格式必须相同 PERIOD_ADD(P,N) 增加N个月,P格式为YYMM或YYYYMM,返回格式YYYYMM PERIOD_DIFF(P1,P2) 月相减,P1、P2格式为YYMM或YYYYMM,返回格式YYYYMM TIMESTAMP(expr1,expr2) TIMESTAMP相加 TIMESTAMPADD(unit,interval,datetime_...
Time difference in minutes: SELECT ROUND(TIME_TO_SEC(timediff(date1,date2))/60) AS diff Example: SELECT ROUND(TIME_TO_SEC(timediff('2014-01-01 11:29:00','2014-01-01 07:27:21'))/60) AS diff Result: 242 Time difference in hours: SELECT ROUND(TIME_TO_SEC(timediff(date1,date...
TIMEDIFF (datetime1 ,datetime2 ) //两个时间差 TIME_TO_SEC (time ) //时间转秒数] WEEK (date_time [,start_of_week ]) //第几周 YEAR (datetime ) //年份 DAYOFMONTH(datetime) //月的第几天 HOUR(datetime) //小时 LAST_DAY(date) //date的月的最后日期 ...
除了使用TIMEDIFF()函数,我们还可以直接对DATETIME或TIMESTAMP类型进行相减操作,得到的结果为TIME类型。 示例代码 SELECTevent_id,(end_time-start_time)ASduration,(TIMESTAMPDIFF(SECOND,start_time,end_time)/60)ASduration_in_minutesFROMevents; 1.
