Question

My database is structured like this:

Number | Month | Country
------------------------
63     | June  | Ireland
48     | June  | England
55     | June  | Spain
66     | May   | Ireland
33     | May   | England
53     | May   | Spain
44     | April | Ireland
44     | April | England
44     | April | Spain

I want to use an SQL statement to call this from the data above. Can anyone help me out please. Basically I want to split the number column into multiple other columns according to the month associated with it. I’m using sql-server 2000

Country | June | May | April
---------------------------
Ireland | 63   | 66  |  44
England | 48   | 33  |  44
Spain   | 55   | 53  |  44

Answer 1

That process is called pivoting. One way to do it:

 select  Country
 ,       sum(case when Month = 'June' then Number end) as June
 ,       sum(case when Month = 'May' then Number end) as May
 ,       sum(case when Month = 'April' then Number end) as April
 from    YourTable
 group by
         Country
