here i need the sum(total_qty) in this query? how to achieve this

Answer 1

Just modify GROUP BY, adding WITH ROLLUP:

SELECT a.id AS supplier, sum( processed_weight ) AS total_qty
FROM supplier_inward a
  INNER JOIN warehouseb ON a.id = b.supplier
WHERE a.master_product_id = '38'
GROUP BY b.supplier
  WITH ROLLUP

Output:

supplier    total_qty
12046       475.00
12482        99.00
NULL        574.00
