how to combine two 'count' value from different tables (2 column, NOT union)

Question

I want to get the count of addmited records by user in 2 table. for example, I have a list of users(table STF) and want to know how many product did a user create (in table PV1) and how many product did he sell (in table dpq), I want to show these data like below:

I have these 2 queries, and don't know how to show them in one table with 3 columns...

Query 1:

select staff_username,  COUNT(*)  as 'count 1'
from STF right join PV1 on STF.staff_username = PV1.admit_user
group by staff_username, staff_name + ' ' + staff_family

Query 2:

select trf_staff_id, COUNT(trf_staff_id)
from dpq join stf on trf_staff_id = stf.staff_username
group by trf_staff_id

Answer 1

You can try joining two queries like this. From limited info which you have provided it seems that staff_username is same as trf_staff_id as you have used it in join condition of second query.

SELECT
    staff_username,
    count_1,
    count_2 FROM
    (
        SELECT
            staff_username,
            COUNT(*) AS count_1
        FROM
            STF
        RIGHT JOIN
            PV1
        ON
            STF.staff_username = PV1.admit_user
        GROUP BY
            staff_username,
            staff_name + ' ' + staff_family ) QRY_CNT_1 INNEER JOIN
    (
        SELECT
            trf_staff_id,
            COUNT(trf_staff_id) AS count_2
        FROM
            dpq
        JOIN
            stf
        ON
            trf_staff_id = stf.staff_username
        GROUP BY
            trf_staff_id ) QRY_CNT_2 ON
    QRY_CNT_2.trf_staff_id = QRY_CNT_1.staff_username
