Hi List,
A general question:
Why does this query:
> area > 10000000000 & area < 100000000000
return the entire dataset,
when this query (same but with brackets):
> (area > 10000000000) & (area < 100000000000)
returns the correct subset?
Surely they both evaluate to the same thing - my (limited) understanding of
boolean logic says they both equate to the same thing because there is only
the one logical operator so strictly speaking the brackets are not
necessary.
Is my understanding of the logic wrong, or should that work?
Cheers,
Jonathan
