Question

is it possible to do a single SQL query to group a table twice?

let’s say i have a table of people belonging to different groups.
i want to see:

group1  males    14
group1  females  15
group2  males    23
group2  females  25
...

what’s the best general approach to achieve this?
is it possible to do with a single query or do i need to use the UNION operator?

Answer 1

Yes it is possible in mysql….

Select * from table GROUP BY column1, column2
