I want to select all row from two tables and one row from last table mysql
My table is given below,
tbl_order
order_id order_no
-------- --------
1 1000
2 1001
3 1002
tbl_assign
assign_id order_id central_status
--------- -------- --------------
1 1 1
2 2 1
3 3 1
tbl_unit_status
status_id assign_id status_status
--------- --------- -------------
1 1 Work
2 2 Cutter
3 2 Stitch
4 1 Stitch
From the above 3 table, I want the result as,
order_id order_no assign_id status_status
-------- -------- --------- -------------
3 1002 3 {null}
2 1001 2 Stitch
1 1000 1 Stitch
I have tried the below code,
SELECT * FROM tbl_order o LEFT JOIN tbl_assign a ON a.order_id = o.order_id LEFT JOIN (SELECT * FROM tbl_unit_status u ORDER BY u.status_id DESC LIMIT 1) uu ON uu.assign_id = a.assign_id WHERE a.central_status = 1 ORDER BY a.assign_id DESC
But the result comes as,
order_id order_no assign_id status_status
-------- -------- --------- -------------
3 1002 3 {null}
2 1001 2 {null}
1 1000 1 Stitch
Where am doing wrong. I have tried a lot. Please help me find the answer. Thank you.
