Re: SQL equivalent of query/400 needed

Iam using libraries when doing SQL. I dont think this is library list issue.

As per Steve Richter post
"If the count is high with your join query check that there is more
than 1 b row for every matching a row.
with t1 as (
select a.sbkrnm, b.srcdta, count(*) joinCount
from file1 a
join file2 b
on a.sbkrnm = b.srcdta
group by a.sbkrnm, b.srcdta
)
select * from t1 where joinCount > 1 "

I ran the above SQL , I am seeing all SBKRNM & SRCDTA displayed. I dont know why?


SRCDTA is a line in a source member? What is SBKRNM?

Does file1 contain unique SBKRNM rows where A.SQCDE IN('SA', 'SB',
'SD', 'SG', 'SH'))?

is file 2 unique on the SRCDTA column?
