mysql minutes to hours and minutes

Question

I have a table that return minutes from a task and I'd like to convert into hours and minutes.

my select is:

select
m.mat_nome as 'Matéria',
round(
    sum(
        case when Hour(TIMEDIFF(est_horario_inicial, est_horario_final))*60 = 0 
            then Minute(TIMEDIFF(est_horario_inicial, est_horario_final))
            else Hour(TIMEDIFF(est_horario_inicial, est_horario_final))*60
        end
    )/60
 ,2)
as 'tempo' from estudos_realizados e
left join materias m on e.mat_id = m.mat_id; 

so this is returning 100 minutes from my table and 1.67 when divided by 60. I'd like to get the result 1h40m The hours and minutes.

This is possible? How can I divide the number to 60 and mod the decimals to 60?

Thank you!

Solution 1

You should look up FLOOR() function, and simple math. You need something like

CONCAT(FLOOR(minutes/60),'h ',MOD(minutes,60),'m') 

Solution 2

CONCAT(FLOOR(minutes/60),':',LPAD(MOD(minutes,60),2,'0'))

a variation on Damir Kasipovic's code: this converts 62 minutes to '1:02'

Solution 3

Why not simply do something like this?

select convert(date_add('2000-01-01', interval 146 minute), time);

This returns 02:26:00

Or the following if you want to specify return format

select date_format(date_add('2000-01-01', interval 146 minute), '%h:%i');
