Unfortunately mysql does not have any inbuilt pivot function so you need to either write a dynamic sql for the unknown set of pivot element or can use the most commonly used pivot generating technique for known set of pivot element, and in your case its known set since you are looking at pivot data from hour1 till hour23 and it could be done as

select
sum( case when HOUR = 1 then price else 0 end) as `HOUR1`,
sum( case when HOUR = 2 then price else 0 end) as `HOUR2`,
sum( case when HOUR = 3 then price else 0 end) as `HOUR3`,
sum( case when HOUR = 4 then price else 0 end) as `HOUR4`,
sum( case when HOUR = 5 then price else 0 end) as `HOUR5`,
sum( case when HOUR = 6 then price else 0 end) as `HOUR6`,
sum( case when HOUR = 7 then price else 0 end) as `HOUR7`,
sum( case when HOUR = 8 then price else 0 end) as `HOUR8`,
sum( case when HOUR = 9 then price else 0 end) as `HOUR9`,
sum( case when HOUR = 10 then price else 0 end) as `HOUR10`,
sum( case when HOUR = 11 then price else 0 end) as `HOUR11`,
sum( case when HOUR = 12 then price else 0 end) as `HOUR12`,
sum( case when HOUR = 13 then price else 0 end) as `HOUR13`,
sum( case when HOUR = 14 then price else 0 end) as `HOUR14`,
sum( case when HOUR = 15 then price else 0 end) as `HOUR15`,
sum( case when HOUR = 16 then price else 0 end) as `HOUR16`,
sum( case when HOUR = 17 then price else 0 end) as `HOUR17`,
sum( case when HOUR = 18 then price else 0 end) as `HOUR18`,
sum( case when HOUR = 19 then price else 0 end) as `HOUR19`,
sum( case when HOUR = 20 then price else 0 end) as `HOUR20`,
sum( case when HOUR = 21 then price else 0 end) as `HOUR21`,
sum( case when HOUR = 22 then price else 0 end) as `HOUR22`,
sum( case when HOUR = 23 then price else 0 end) as `HOUR23`,
product,
mode,
region
from mytable 
group by product,mode,region;
