我想在具有特定ID的同一表中将值从一列减去另一列

Question

Proc Id       Start_time             end_time                Status
111           7/4/2017 9:08:43 AM    7/4/2017 9:35:54 AM     Success

我想找到star_time和end_time之间的持续时间（以分钟为单位）。 请帮我怎么做？

Answer 1

你可以试试这个......

SELECT TIMESTAMPDIFF(MINUTE,tmp.start_time,tmp.end_time) FROM (select start_time,end_time from table_name where id=?) as tmp;

Answer 2

SELECT TIMESTAMPDIFF(MINUTE,STR_TO_DATE(Start_time,'%d/%m/%Y %H:%i:%s),STR_TO_DATE(end_time,'%d/%m/%Y %H:%i:%s)) from TABLENAME;

尝试以上查询。希望这对您有帮助。
