Re: SQL looking for differences in rows in same table

I've not iced a number of posts using the WITH statement. I am not familiar
with this and tried to find an overview in the SQL manuals but could not
find any reference.
Can someone tell me what I should be searching for so I can look it up
myself.

Thanks,

Rob

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.
