Help creating a report

Question

Hello people I need some help creating a report on 9i. So far:
SELECT TRUNC(sampled,'MM'), c.name country, o.name operator, SUM(SMS)
FROM TEST s, operators_info o, countries_info c
WHERE sampled >= '01/01/2010' AND sampled < '01/01/2011'
AND s.dest_id = o.id
AND o.country_id = c.id
GROUP BY TRUNC(sampled,'MM'), c.name, o.name
ORDER BY 1, 2, 3;
I am getting:
01/01/2010 UK OPERATOR1 100
01/01/2010 UK OPERATOR2 150
01/01/2010 USA OPERATOR3 500
01/01/2010 USA 0PERATOR4 650
01/02/2010 UK OPERATOR1 50
01/02/2010 UK OPERATOR2 170
01/02/2010 USA OPERATOR3 550
01/02/2010 USA 0PERATOR4 670
01/12/2010 UK OPERATOR1 0
01/12/2010 UK OPERATOR2 270
01/12/2010 UK OPERATOR3 150
01/12/2010 USA OPERATOR3 570
01/12/2010 USA 0PERATOR4 800
How can I create a more efficient report like:
........................01/01/2010...01/02/10...01/12/2010
UK OPERATOR1...100.............50.............0
UK OPERATOR2...150.............170...........270
UK OPERATOR3......................................150
USA OPERATOR3.500..............550............570
USA 0PERATOR4.650..............670.............800
Thank you very much in advance

Hi,
That's called a Pivot , and this thread shows you how to do it:
Help for a query to add columns
Pivoting the output requires more work, so it probably won't be any more efficient that what you're doing now.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only), and the results you want from that data.
Explain how you get those results from that data.
Always say what version of oracle you're using.
