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 per

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
roduct p on pm.product_id = p.id inner join
location l on pm.destination_location = l.id
and datetime < '2012-12-31'
I'm not what 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 desti
uct_id, l.id as location_id
FROM product_move pm inner join product p on pm.product_id = p.id inner join
location l on pm.destination_location = l.id
and datetime BETWEEN '2010-1-01' AND '2012-12-31'

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,

ove this causes up problems as we have to create all views to point directly
to the table rather than deriving them from other views.
Any ideas?
