Sorry, why do you need the joins?
Best,
Oliver
Strictly speaking, for the examples and results given, the joins are pointless
when you can get all the info from the 'move' table (but then the problem is
like the 'hello world' of SQL)
But then the other 2 tables are completely redundant in
'
group by product_id
) X
on pm.product_id = X.product_id and pm.datetime = X.datetime
Thus you will know where every product was coming into the period and every
subsequent destination it was moved to within that period.
(although I'm still not sure this is what you want)

the use of the 'from' date is in your examples.
Do you need to know the final destination of the product in that time period?
Or every destination location of the product in that time period?

Hi Tom,
Thanks for that, that was exactly the issue.
It absolutely is IMMUTABLE and changing it from VOLATILE has fixed the issue.
Much appreciated,
Russell,
