Re: SQL Question

I'm not sure the structure of the data you have is enough to answer your
question...

How do you know that
boxB, 1, widget2
boxB, 1, widget3

Held both types of widgets at the same time? Seems just as likely that at
some point boxB was used to ship 1xwidget2 and at another time was used for
1xwidget3.

It's an interesting challenge, certainly seems set based. So I'd think SQL
should be able to provide an answer.
But I'd definitely call the solution non-trivial...

Possible paths,
using the INTERSECT of two results sets, this would give you all boxes
that had contained at least the desired objects. But you'd have to then
discard the boxes with extras.

Using LISTAGG, to build a string 'widget2@1|wudget3@1' that you could
search for directly. You'd have to be careful about how you combined qty &
sku. But this might be the best performance as you could pre-calculate and
store the historical data.

We have a historical table containing what items we previous packed into

what box to use when packing the same items/qty again.

BOX TYPE, QTY, SKU

Data might look like this

boxA, 3, widget1
boxA, 1, widget2
boxA, 1, widget3
boxB, 1, widget2
boxB, 1, widget3

And so forth. This means that "boxA" can hold 3 of widget1 and 1 each of
widget2 and widget3

I would like to query the table to so what box type to use when I have 1
of widget2 and 1 of widget3 (i.e. find "boxB"). In other words, find a
"matching" box type for my current two rows.
1 widget2
1 widget3

Is this even possible with SQL?
