Re: SQL looking for differences in rows in same table

Originally, no...

But I just did. It looks fine given the initial test data....

However, try adding a row

insert into qtemp/mytbl
values ( 1, 1, 277, '25')

The new row will be returned, and I'd imagine that it shouldn't be.
Since the OP was looking for differences.

Honestly, initally my response was a gut feel based upon seeing
ITEM,VENDOR and HAVING COUNT(*) =
1

But I had to run
SELECT ITEM, VENDOR, COUNT(*) FROM qtemp/MYtbl B
WHERE 303 = B.ITEM
GROUP BY ITEM, VENDOR

SELECT ITEM, VENDOR, COUNT(*) FROM qtemp/MYtbl B
WHERE 256 = B.ITEM
GROUP BY ITEM, VENDOR

Just now to understand why your statement came as close as it did. :)

Charles,

My apologies, but my example (as well as yours) worked on our system. Did
you get any different results (just curious).

That's not quite right...

This would work...

SELECT * FROM MYFILE A
WHERE EXISTS(
SELECT count(distinct vendor) FROM MYFILE B
WHERE A.ITEM = B.ITEM
HAVING COUNT(distinct vendor) > 1 )

Dave,

Just a quick try, so not very sure if this could work in every case:

SELECT * FROM MYFILE A
WHERE EXISTS(
SELECT ITEM, VENDOR, COUNT(*) FROM MYFILE B
WHERE A.ITEM = B.ITEM
GROUP BY ITEM, VENDOR
HAVING COUNT(*) = 1 )

Sorry I was not clearer. I want to be able to distinguish between

rows

where the Item is the same, but the Vendor is different, and I want

to

see a list of all the records in which this is true. From my example
table, I would like to see all of the 256 rows (since amongst them,

the

vendors are all not the same) but would not like to see any of the

303

rows. And I want to see all four(4) 256 rows, even though two (2) of
them share the same vendor.

I have a table where my data would be like

Company Warehouse Item Vendor
1 1 256 25
2 1 256 *blanks
3 1 256 24
4 1 256 24
1 1 303 25
2 1 303 25

What I am looking to do is generate a list which will show all of

the

Item 256 rows (since these rows are not all the same) but not show

any

of the Item 303 rows.
