Juraj Duráni updated TEIID-4265:
--------------------------------
Attachment: plans_metadata.zip
ZIP archive contains metadata for 6.2.0.GA and for 6.3.0.ER3 and query plans for GA, ER3,
ER4 and ER4.1.
I have used first query from "02" set. All queries from "02" set are
similar.
{code:sql}
select
s_acctbal,
s_name,
n_name,
p_partkey,
p_mfgr,
s_address,
s_phone,
s_comment
from
tpch2.tpch.part,
tpch1.tpch.supplier,
tpch2.tpch.partsupp,
tpch1.tpch.nation,
tpch1.tpch.region
where
p_partkey = ps_partkey
and s_supplierkey = ps_supplierkey
and p_size = 23
and p_type like '%COPPER'
and s_nationkey = n_nationkey
and n_regionkey = r_regionkey
and r_name = 'AMERICA'
and ps_supplycost = (
select
min(ps_supplycost)
from
tpch2.tpch.partsupp,
tpch1.tpch.supplier,
tpch1.tpch.nation,
tpch1.tpch.region
where
p_partkey = ps_partkey
and s_supplierkey = ps_supplierkey
and s_nationkey = n_nationkey
and n_regionkey = r_regionkey
and r_name = 'AMERICA'
)
order by
s_acctbal desc,
n_name,
s_name,
p_partkey;
{code}
