Sql count distinct values

Question

I am trying to count distinct values grouped by different column this is my table: product

id	typePr	namePr
1	typeA	nameA
2	typeeB	nameC
3	typeA	nameB
4	typeA	nameB
5	typeB	nameA
6	typeB	nameC
7	typeC	nameB

I wanna get something like this:

[{"typePr":"typeA","nameA":"1","nameB":"2"}, {"typePr":"typeB","nameC":"2","nameA":"1"}, {"typePr":"typeC","nameB":"1"} ]

is there any possibility to do this?

Answer 1

The general query you want here uses GROUP BY :

SELECT age, SUM(gender = 'F') AS countF, SUM(gender = 'H') AS countH
FROM yourTable
GROUP BY age;

As for turning your result set into JSON, you could try to do this from MySQL, but more typically you would handle this from your presentation layer (eg PHP).
