Re: SELECT - parenthesis ignored by Oracle ???

See post from others.
Also you have to bear in mind that parenthesis will be 'ignored' in your particular statement since you are using all ANDs. If your statements had ORs, NOTs etc, the stuff in parenthesis will be worked out first and the OR or NOT logic applied (hope that makes sense, no time to explain by example!)

Your statement will be interperated as

select distinct(year || period)
from IC_BIN_MOVEMENTS
WHERE WAREHOUSE='SF'
AND PERIOD <> 10
AND YEAR <> 2001;

To actually get the results your require, try

select distinct(year || period)
from IC_BIN_MOVEMENTS
WHERE WAREHOUSE='SF'
AND year || period <> '200110';

Its not efficient index-wise but does the job.
