Run Queries on Data
On this page
Now that the data is all loaded into your instance, you can start running queries on the database.
First, open up your SQL Editor to begin querying the data.
Query 1: Pricing Summary Report
This query reports the amount of business that was billed, shipped, and returned within 60 - 120 days of the greatest ship data contained in the database.
use tpch;selectl_returnflag,l_linestatus,sum(l_quantity) as sum_qty,sum(l_extendedprice) as sum_base_price,sum(l_extendedprice * (1 - l_discount)) as sum_disc_price,sum(l_extendedprice * (1 - l_discount) * (1 + l_tax)) as sum_charge,avg(l_quantity) as avg_qty,avg(l_extendedprice) as avg_price,avg(l_discount) as avg_disc,count(*) as count_orderfromlineitemwherel_shipdate <= date('1998-12-01' - interval '90' day)group byl_returnflag,l_linestatusorder byl_returnflag,l_linestatus;
Note
Run the query again and observe the execution time difference.
Query 2: Shipping Priority
This query retrieves the 10 unshipped orders with the highest value.
use tpch;selectl_orderkey,sum(l_extendedprice * (1 - l_discount)) as revenue,o_orderdate,o_shippriorityfromcustomer,orders,lineitemwherec_mktsegment = 'BUILDING'and c_custkey = o_custkeyand l_orderkey = o_orderkeyand o_orderdate < date('1995-03-15')and l_shipdate > date('1995-03-15')group byl_orderkey,o_orderdate,o_shippriorityorder byrevenue desc,o_orderdatelimit 10;
Query 3: Returned Item Reporting
This query identifies top 20 customers who might be having problems with the parts that are shipped to them.
use tpch;selectc_custkey,c_name,sum(l_extendedprice * (1 - l_discount)) as revenue,c_acctbal,n_name,c_address,c_phone,c_commentfromcustomer,orders,lineitem,nationwherec_custkey = o_custkeyand l_orderkey = o_orderkeyand o_orderdate >= date('1993-10-01')and o_orderdate < date('1993-10-01') + interval '3' monthand l_returnflag = 'R'and c_nationkey = n_nationkeygroup byc_custkey,c_name,c_acctbal,c_phone,n_name,c_address,c_commentorder byrevenue desclimit 20;
Query 4: Product Type Profit Measure
This query determines how much profit is made on a given line of parts, broken out by supplier nation and year.
use tpch;selectnation,o_year,sum(amount) as sum_profitfrom(selectn_name as nation,extract(year from o_orderdate) as o_year,l_extendedprice * (1 - l_discount) - ps_supplycost * l_quantity as amountfrompart,supplier,lineitem,partsupp,orders,nationwheres_suppkey = l_suppkeyand ps_suppkey = l_suppkeyand ps_partkey = l_partkeyand p_partkey = l_partkeyand o_orderkey = l_orderkeyand s_nationkey = n_nationkeyand p_name like '%green%') as profitgroup bynation,o_yearorder bynation,o_year desc;
