Question

I need a MySql query to do the following:
Select all the items in a table, group them by a type, order them by count type and also sum all the count.

This is what I’ve done so far:

select type, count(*) as cnt from $tbl_name group by type order by count(*) desc;

This only gives me the count for each group. What should I add so that this code will also show the total count (sum the counts from every group).

Answer 1

select * from (
select type as type, 
count(*) as cnt 
from $tbl_name 
group by type WITH ROLLUP) as inner_table
order by cnt desc;

Note that the first row will be the rolled up total sum.

ROLLUP reference
