You wether mentioned a problem, nor what you have already tried.

[selvameena62]

SET @statmt=null;
SELECT GROUP_CONCAT(DISTINCT CONCAT('max(CASE WHEN prod_name = "',prod_name,'" THEN ',prod_qty,' end) AS "',prod_name,'"'))
INTO @statmt FROM  sup_prod_det  ;
SET @statmt = CONCAT('SELECT sales_stk_sup.st_sup_id,',@statmt,'FROM sales_stk_sup join sup_prod_det on 
sales_stk_sup.st_sup_id=sup_prod_det.st_sup_id group by st_sup_id');
PREPARE stmt FROM @statmt;
EXECUTE stmt;
DEALLOCATE PREPARE stmt; 

i have tried this, but it throws the wrong result

May be better asking in the ‘database’ section, there’s no PHP content as far as I can see. Should there be a space before “FROM” in that query?

you’re looking for PIVOT

which version of SQL are you using?

OP says:

Mysql version is ‘5.7.19-log’
