Aren't you much better off doing raid 0 over raid 1?
With raid 1 over raid 0 you're mirroring two stripe sets. That means if any

Without starting too much controvesy I hope, I would seriously

I created a temporary table:
create table statesnew as select distinct state,state_code from postalcode where lower(country)='us';
And then changed the query to :
SELECT (SELECT sn.state FROM statesnew sn WHERE U
Please post in plaintext, not html where possible.
Your group by clause was 'myst'...was that supposed to be mystate?
Her is something you might try...use the original query form and create a
function which resolves the state code from the input data...you are already
doing that with upper.
So,
Hi All,
I have the following query to generate a report grouped by "states".
SELECT distinct upper(cd.state) as mystate, SUM(d.amount) as total_amount, SUM(COALESCE(d.fee,0) + COALESCE(mp.seller_fee, 0) + COALESCE(mp.buyer_fee,0)) as total_fee FROM data d left JOIN customerdata cd ON d.uid = cd
