Re: SQL looking for differences in rows in same table

I know this is an older post, but I have a slightly different approach than any of the others posted.

With TT As (
Select ITEM, Count(distinct VENDOR)
From TESTFILE
Group By ITEM
Having Count(Distinct VENDOR) > 1)
select * from TESTFILE join TT on TESTFILE.ITEM = TT.ITEM

This uses a CTE table containing only ITEMs with more than one Distinct VENDOR attached. That CTE (named TT) is then used in a Join with the original file (called TESTFILE in my example) to restrict results to full records for ITEMs with multiple VENDORs.

Subject: SQL looking for differences in rows in same table

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.
