Fergal,
Thanks - worked perfect. I'll remember that NOT () syntax for next time, instead of using double operators.

Hi Chris,

The query is returning the correct result. If you want to exclude may 2012 then the filter is NOT ( month = 5 and year = 2012 )

Well, this gives me the right results but I don't understand why...

(change the AND to an OR)

select
tm.month, tm.year, count(*)
 from img.ton_miles tm
where (tm.month != 5 OR tm.year != 2012) group by tm.month, tm.year
order by 1,2

I'm a bit fuzzy at the moment due to pain meds after a minor surgery so I'm hoping someone can spot my error (if I have an error)

Table has months, years and 'x' number of rows for each

The table has Years 2011 and 2012
In 2011, it has months 1-12
And in 2012 it has months 1-5

I run this:
Select month, year, count(*) -- month, and year are actual column names From some_table Where (month != 5 and year != 2012) Group by month, year /

The data set I get is Months 6-12 for 2011 *ONLY*

Shouldn't that query *ONLY* exclude MONTH=5 and YEAR 12 together? (instead of ALL 2012 and ALL 5s?)
