Question

Say you have a table such as:

id   status  date
-----------------------
1    2       today
2    3       today
3    3       yesterday
4    2       yesterday
5    1       yesterday

And you want a query that counts the number or results that have the status 1, 2 or 3 for a given date, in the example the desired result set would be:

date        status 1   status 2  status 3 
            count      count     count 
------------------------------------------
today       0          1         1
yesterday   1          1         1

Can anyone point me in the right direction?. Thank you.
