Can you help me under the optimized code and ask how to make cross table

[ximen]

ps.parent_id To the column value ,the ps.customer_id ,ps.short_name is row, sum(ps.quantity) is the value

WITH RECURSIVE PS ( product_code,description,parent_id,customer_id,short_name,quantity) as
    (select product_code,description,parent_id,'ID' D,'Sname' E,F=1000000.00*0  from product_code where parent_id='CP'
     union all
    select b.product_code,b.description,b.parent_id,cu.customer_id,cu.short_name,shl.quantity  from ((((ps p join product_code b on p.product_code=b.parent_id ) join part s on b.product_code=s.product_code) join shipper_line shl on s.part_id=shl.part_id) join shipper sh on shl.trans_no=sh.trans_no) join customer cu on sh.customer_id=cu.customer_id)
    select  ps.parent_id,product_code.description ,ps.customer_id  ,ps.short_name ,sum(ps.quantity   from ps,product_code

where ps.parent_id  in (select product_code from product_code where parent_id='CP') and product_code.product_code=ps.parent_id  group by ps.parent_id,product_code.description,ps.customer_id,ps.short_name order by ps.parent_id
