count for different column in union and displaying in same row - mysql

Question

I am trying to get a count(*) for different column from a different table using union.
//tbl_churidar
order_id order_no_first order_no
--------------------------------------
1 C 1000
2 C 1001
3 C 1002
//tbl_anarkali
order_id order_no_first order_no
--------------------------------------
1 A 1003
2 A 1004
3 A 1005
//tbl_assign
assign_id order_id order_no_first
---------------------------------------
1 1 C
2 1 A
3 2 C
4 3 C
5 2 A
6 3 A
//tbl_unit_status
status_id assign_id status_status stitching_worker
-----------------------------------------------------------
1 1 Stitch AA
2 2 QC {null}
3 3 Stitch BB
4 4 Stitch BB
5 5 Stitch AA
6 6 Stitch CC
from the table tbl_unit_status where status_status = Stitch should INNER JOIN with other two table and get the total count of churidar and anarkali each stitching_worker taken.
the required output is,
churidar anarkali stitching_worker
----------------------------------------
1 1 AA
2 0 BB
0 1 CC
I have tried to get the above output but got stuck. Below is my code,
SELECT churidar, anarkali, stitching_worker
FROM ((
SELECT count(*) AS churidar, NULL AS anarkali,
us.stitching_worker
FROM tbl_unit_status us
INNER JOIN tbl_assign a ON a.assign_id = us.assign_id
INNER JOIN tbl_churidar o ON
(o.order_id = a.order_id AND
o.order_no_first = a.order_no_first)
INNER JOIN tbl_contacts c ON c.contacts_id = o.contacts_id
LEFT JOIN tbl_title t ON t.title_id = c.title_id
WHERE us.status_status = "Stitch" AND
o.order_no_first = "C"
GROUP BY us.stitching_worker
)
UNION (
SELECT NULL AS churidar, count(*) AS anarkali,
us.stitching_worker
FROM tbl_unit_status us
INNER JOIN tbl_assign a ON a.assign_id = us.assign_id
INNER JOIN tbl_anarkali o ON (
o.order_id = a.order_id AND
o.order_no_first = a.order_no_first)
INNER JOIN tbl_contacts c ON c.contacts_id = o.contacts_id
LEFT JOIN tbl_title t ON t.title_id = c.title_id
WHERE us.status_status = "Stitch" AND
o.order_no_first = "A"
GROUP BY us.stitching_worker
)
) AS T1
the output for the above code is,
churidar anarkali stitching_worker
----------------------------------------
1 0 AA
{null} 1 AA
2 0 BB
0 1 CC
how to get the required output. I have tried a lot. Help me find the answer. Thankyou.

If I understand correctly (which I may not), you don't need the first two tables. You can get the information you need from tbl_assign and just use aggregation:
select us.stitching_working,
sum(a.order_no_first = 'C') as churidar,
sum(a.order_no_first = 'A') as anarkali
from tbl_unit_status us join
tbl_assign a
on us.assign_id = a.assign_id
where us.status_status = 'Stitch'
group by us.stitching_working;
