Pivot Tables PHP/MySQL

Question

What\'s the best way of handling pivot tables in php/MySQL (or something to that effect)

I have a query that returns information as below

id      eng         


        

Answer 1

You can likely do this with a sub-query and then produce and aggregation of this data. Try something along the lines of this:

select week, 
    count(*) as total, 
    sum(technical) as technical, 
    sum(non_technical) as non_technical) 
from(
    select week, 
    case(type) when 'Technical' then 1 else 0 END as technical, 
    case(type) when 'Non-Technical' then 1 else 0 END as non_technical
) as data
GROUP BY week
