You could do this with a query that used "Where exists" a couple of times to make sure those two parts were in the same box, and another "where not exists" maybe to make sure nothing else was used in that box. However, that query would not work for a variable number of stuff in the boxes, so, if that's what you actually want, it gets more complicated and would be more around how your program is written.

Subject: SQL Question

We have a historical table containing what items we previous packed into different boxes. I'd like to draw on that historical data to extrapolate what box to use when packing the same items/qty again.


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?
