Cant we do this
Select taxmonth, Max(clothing+electronics+sports)
From eshop
Group by 1

[@saib7231]

no this is syntax wise all
instead you can use this
Select taxmonth, sum(cast(clothing as int)+cast(electronics as int)+cast(sports as int)) as total_sales
From eshop
Group by taxmonth
order by total_sales desc
limit 1
