sql query to return display by month

Question

I am trying to generate a query which returns results based on month.

For example: table1

Name     Amount   createDate
p1        100      01/01/2012
p1         50      02/01/2012
p1        200      03/01/2012
p3        100      04/01/2012

The query should return:

Name Jan   Feb   Mar   April
p1   100   50    200    0
p2    0     0     0    100 

Any suggestion or any idea of how to do it.

I am using db2 database.Sorry for missing the details

Answer 1

Something like this might work...

select
  name, 
  case when month(createDate) = '1' then amount end as Jan,
  case when month(createDate) = '2' then amount end as Feb
  --etc...
from
  table1
group by
  name
;

However, the date equality test may not pass muster. Like the others said, you'll probably have to look up date functions and find the one that suits your needs.
