Convert HH:MM:SS string to number of minutes

问题:

I have the below query.

select cast(dateadd(minute, datediff(minute, TimeIn, TimeOut), 0) as time(0) )

I get the results from two columns in the format of hrs-min-seconds. I would like it in the format of min only. So 02:47:00 will read 167.

For SQL Server (works for 2005 too):

select Datediff(mi,convert(datetime,'00:00:00',108), convert(datetime,'02:47:00',108))

SQL Server Query:

SELECT cast(substring('02:47:00',1,2) AS int)*60+
       cast(substring('02:47:00',4,2) AS int)+ 
       cast(substring('02:47:00',7,2) AS int)/60.0 AS minutes

MYSQL Query:

SELECT TIME_TO_SEC('02:47:00') / 60

Result:

| MINUTES |
-----------
|     167 |

回答3:

declare @Time DATETIME = '01:05:00'

select ((DATEPART(HOUR, @Time)*60) + (DATEPART(MINUTE, @Time)))

Try this:

datediff(minute, 0, '02:47')

Expanding on Justin's answer. This allows for situations where hours is larger than 2 digits.

declare @time varchar(50) = '102:47:05'

SELECT cast(right(@time,2) AS int)+
       cast(left(right(@time,5),2) AS int)*60+ 
       cast(left(@time,len(@time)-6) AS int)*3600 AS seconds,
       (cast(right(@time,2) AS int)+
       cast(left(right(@time,5),2) AS int)*60+ 
       cast(left(@time,len(@time)-6) AS int)*3600)/60.0 AS minutes

Result:

seconds     minutes
----------- ---------------------------------------
370025      6167.083333

回答6:

SELECT DATEDIFF(minute,CAST('00:00' AS TIME), CAST('02:47' AS TIME)) AS difference

Gives you:

| DIFFERENCE |
--------------
|        167 |

回答7:

$time = '02:47:00';

$time = explode(":",$time); 

$total = ($a[0]*60)+$a[1];

echo 'Minutes : '.$total;<br>
echo 'Seconds : '.$a[2];
