SUM time values MySQL [duplicate] - mysql

Surpassing MySQL's TIME value limit of 838:59:59
(7 answers)
Closed 4 years ago.
I am trying to sum time values and have it in the format of hours:minutes:seconds i.e. 100:30:10.
SEC_TO_TIME(SUM(TIME_TO_SEC(ActualHours))) AS Hours
But I'm having a problem because time's max value is 838:59:59.
So if summing the time is over this value it won't show i.e. if it equals 900 hours it will show as 838:59:59 which is wrong.
How do I the display the total hours if it is over 838:59:59?

Answer 1

If I had to do this conversion in SQL, I would do something like this:
SELECT CONCAT( ( _secs_ DIV 3600)
, ':'
, RIGHT(CONCAT('0',( _secs_ DIV 60 ) MOD 60 ),2)
, ':'
, RIGHT(CONCAT('0',( _secs_ MOD 60)),2)
) AS `h:mm:ss`
We can just replace the _secs_ with the expression that returns the number of seconds we want to convert. Using the expression given in the question, we get something like this:
SELECT CONCAT( ( SUM(TIME_TO_SEC(ActualHours)) DIV 3600)
, ':'
, RIGHT(CONCAT('0',( SUM(TIME_TO_SEC(ActualHours)) DIV 60 ) MOD 60 ),2)
, ':'
, RIGHT(CONCAT('0',( SUM(TIME_TO_SEC(ActualHours)) MOD 60)),2)
) AS `h:mm:ss`
DEMONSTRATION
The syntax provided in this answer is valid in MySQL 5.6. As a demonstration, using a user-defined variable #_secs as the expression number of seconds:
Set user-defined variable for demonstration:
SELECT #_secs_ := ( 987 * 3600 ) + ( 5 * 60 ) + 7 ;
returns
#_secs := ( 987 * 3600 ) + ( 5 * 60 ) + 7
-----------------------------------------
3553507
demonstrating the query pattern:
SELECT CONCAT( ( #_secs_ DIV 3600)
, ':'
, RIGHT(CONCAT('0',( #_secs_ DIV 60 ) MOD 60 ),2)
, ':'
, RIGHT(CONCAT('0',( #_secs_ MOD 60)),2)
) AS `hhh:mm:ss`
returns
hhh:mm:ss

987:05:07

Answer 2

Here is one way we can do this:
SELECT
CONCAT(CAST(FLOOR(seconds / 3600) AS CHAR(50)), ':',
CAST(FLOOR(60*((seconds / 3600) - FLOOR(seconds / 3600))) AS CHAR(50)), ':',
CAST(seconds % 60 AS CHAR(50))) AS time
FROM yourTable;
For an input of 10,000,000 (ten million) seconds, this would generate:
2777:46:40

Answer 3

Use some simple math to concat a time period from seconds,replace 35000 with your column.
SELECT CONCAT(FLOOR(35000/3600),':',FLOOR((35000%3600)/60),':',(35000%3600)%60)
