l_shipdate <= date('1998-12-01') - 69 days
Someone must have done some really creative thinking with the generated
query ;-)

If anyone wants to see the all actual queries that IBM used for the TPC-H
benchmark they are documented teh following link (posted on the TPC
website):
http://www.tpc.org/results/FDR/tpch/...030810.fdr.pdf
The query in question appears to be Query 1 of the TPC-H benchmark which is
documented on page 92 of the above referenced document.
Here is the entire query #1:
select
l_returnflag,
l_linestatus,
sum(l_quantity) as sum_qty,
sum(l_extendedp rice) as sum_base_price,
sum(l_extendedp rice * (1 - l_discount)) as
sum_disc_price,
sum(l_extendedp rice * (1 - l_discount) * (1 + l_tax))
as sum_charge,
avg(l_quantity) as avg_qty,
avg(l_extendedp rice) as avg_price,
avg(l_discount) as avg_disc,
count(*) as count_order
from
tpcd.lineitem
where
l_shipdate <= date ('1998-12-01') - 90 day
group by
l_returnflag,
l_linestatus
order by
l_returnflag,
l_linestatus
On page 17 of the above linked document, the query modifications made by IBM
are disclosed in accordance with Clause 2.2.3 of the TPC-H benchmark rules.
Appendix C.1, "Qualificat ion Queries," contains the output for each of the
queries. The functional query definitions and variants used in this
disclosure use the following minor query modifications:
- Table names and view names are fully qualified. For example, the nation
table is referred to as "TPCD.NATIO N."
- The standard IBM SQL date syntax is used for date arithmetic. For example,
DATE('1996-01-01') +3 MONTHS.
- The semicolon (;) is used as a command delimiter.
