Question

I have a question on how to sort data using sql. For that I made up a simple example to illustrate my problem.

if object_id('MyTable', 'U') is not null drop table  dbo.MyTable;

create table MyTable
(
    country varchar(10) not null
    , town varchar( 10 ) not null
    , amount int not null
)

insert into MyTable values
( 'US', 'NYC', 100 )
, ( 'US', 'BAL', 150 )
, ( 'US', 'WAS', 200 )
, ( 'CA', 'MON', 100 )
, ( 'CA', 'TOR', 150 )
, ( 'CA', 'VAN', 200 )

How can I sort the data in a sense the all “countries are sorted by the amount in descending order AND that the towns in alphabetical order for each country.

Thanks,
Christian

Answer 1

I think that this should do it:

SELECT
    country,
    SUM(amount) OVER(PARTITION BY country) as CountryTotal,
    town,
    amount
FROM        MyTable
ORDER BY    CountryTotal, country, town
