Hello,
I am trying to validate all the 22-Queries in the TPC-H Benchmark on
DB2 UDB 8.2, I am having a little bit of trouble with Query #8
The result should be:
YEAR MKT_SHARE
1995 .03
1996 .04
But when I run the query, I got the following result:
YEAR MKT_SHARE
1995 .0
1996 .0
I am not really sure what could be wrong, the query syntax is %100
correct. I would really appreciate any help.
Query #8 :
select
o_year,
sum(case
when nation = 'BRAZIL' then volume
else 0
end) / sum(volume) as mkt_share
from
(
select
year(o_orderdate) as o_year,
l_extendedprice * (1 - l_discount) as volume,
n2.n_name as nation
from
part,
supplier,
lineitem,
orders,
customer,
nation n1,
nation n2,
region
where
p_partkey = l_partkey
and s_suppkey = l_suppkey
and l_orderkey = o_orderkey
and o_custkey = c_custkey
and c_nationkey = n1.n_nationkey
and n1.n_regionkey = r_regionkey
and r_name = 'AMERICA'
and s_nationkey = n2.n_nationkey
and o_orderdate between date('1995-01-01') and date('1996-12-31')
and p_type = 'ECONOMY ANODIZED STEEL'
) as all_nations
group by
o_year
order by
o_year;
Regards,
Salem
