I've got a table which can be described as holding one "RefDes" per
row. (They are reference designators in a electronic PCB schematic or
its bill-of-materials.) There are thousands of them, and each one is
very short, inducing the convention of clumping them together for
display in a bill-of-materials so that line counts are held down and
horizontal space is well used. So, starting with a column which might be:
RefDes
------
R1
R2
...
R190
I want to convert it to something like:
R1,R2,...,R50,
R51,R52,...,R100,
R101,R102,...,R150,
R151,...,R190
where the clump length, setting the number of designators per line, is a
parameter. (Ideally, the string length of the clump would be the
criterion, but this is dispensible.)
The converted result is destined for a spreadsheet, and I would really
like the pseudo-table created therein to be a simple projection or view
of the real data. I realize this is not hard to do programmatically,
(having done it a few times), but it would be nice for process/work-flow
reasons to be able to use a query to get the data in presentation form.
If there is no way to get a view that does this, I can create a
derivative database table with the clumping already done
programmatically. But that presents its own issues, such as when to run
the code that creates it.
I'm stumped as to how to do this. I've done the reverse transformation
in SQL, so it seems like this should not be as hard as I have found it
to be.
Thanks for any tips, (even "Give up.")
