Description

for example, sql29 as follows:

select 

  i_item_id,

  i_item_desc,

  s_store_id,

  s_store_name,

  max(ss_quantity) as store_sales_quantity,

  max(sr_return_quantity) as store_returns_quantity,

  max(cs_quantity) as catalog_sales_quantity

from

  store_sales,

  store_returns,

  catalog_sales,

  date_dim d1,

  date_dim d2,

  date_dim d3,

  store,

  item

where

  d1.d_moy = 4

and d1.d_year=1998

and d1.d_date_sk = ss_sold_date_sk

and i_item_sk = ss_item_sk

and s_store_sk = ss_store_sk

and ss_customer_sk = sr_customer_sk

and ss_item_sk = sr_item_sk

and ss_ticket_number = sr_ticket_number

and sr_returned_date_sk = d2.d_date_sk

and d2.d_moy between 4 and 4+3

and d2.d_year = 1998

and sr_customer_sk = cs_bill_customer_sk

and sr_item_sk = cs_item_sk

and cs_sold_date_sk = cs_item_sk

and cs_sold_date_sk = d3.d_date_sk

and d3.d_year in (1998, 1998+1, 1998+2)

group by 

  i_item_id,

  i_item_desc,

  s_store_id,

  s_store_name

order by

  i_item_id,

  i_item_desc,

  s_store_id,

  s_store_name

limit 100;
