I am new to programming and have been scratching my head over this problem for a few hours now.

In short, I have a dataset in postgresql that looks like this (there are 1000s of rows):

DonatorID   YearofDonation  NoofDonations   TotalAmount
2           1998            1               20
2           2000            2               20
2           2001            4               80
2           2005            3               15
2           2006            1               15
3           1999            1               15
3           2000            3               40
3           2014            1               50
4           2015            2               20

I want to collate the data such that I have one row per donator that summarises the number of donations in a year and the total amount i.e. I would like the data to look like this:

DonatorID 1998Don  1998Amt   1999Don    1999Amt ... 2015Don    2015Amt 
2         1          20        0          0     ...    0        0
3         0           0        1          15    ...    0        0
4         0           0        0          0     ...    2        20

I have tried using partition by but cannot seem to get the desired result. Any help would be much appreciated!
