pivot - MySQL converting colums to rows -


i'm trying figure out how count presidents, managers etc , convert columns rows in 1 query. example there sample db 'employee' here: http://www.mysqltutorial.org/tryit/ can count employees of types using query this:

select      sum(case         when jobtitle = 'president' 1         else 0     end) 'presidents',     sum(case         when jobtitle 'vp%' 1         else 0     end) 'vps',     sum(case         when jobtitle '%manager%' 1         else 0     end) 'managers',     sum(case        when jobtitle '%rep' 1        else 0     end) 'reps' employees;

but want convert columns rows , have no idea how include in query similar answer here: mysql convert column row (pivot table ) have idea?

you use sub query standardise job titles, group , order case statement to produce output in descending order of bossiness.

select  jobtitle,count(*) ( select  case          when jobtitle = 'president' 'presidents'         when jobtitle 'vp%' 'vps'         when jobtitle '%manager%' 'managers'         when jobtitle '%rep' 'reps'         end jobtitle employees  ) s  group   jobtitle order  case when jobtitle = 'presidents' 1  when jobtitle = 'vps' 2  when jobtitle = 'managers' 3  when jobtitle = 'reps' 4  end
