Multiple counts in table

I've got a table containing (among some other columns) 3 different type columns.

TABLE
xxxx as int
type 1 as string
type 2 as string
type 3 as string
date as Date

First i'd like to select the number of counts each of these appear in my table. I realized that it can be done by union 3 select statements each grouped by a type.

select type1, count(type1) from table group by type1
union
select type2, count(type2) from table group by type2...

Now this is time consuming and not what I would like to do

Secondly i'll try to do something like

SELECT type1 ,
SUM(CASE WHEN MONTH(date) = 1 THEN 1 END) AS 'Januar'
,SUM(CASE WHEN MONTH(date) = 2 THEN 1 END) AS 'Februar'
,SUM(CASE WHEN MONTH(date) = 3 THEN 1 END) AS 'Mars'
,SUM(CASE WHEN MONTH(date) = 4 THEN 1 END) AS 'April'
,SUM(CASE WHEN MONTH(date) = 5 THEN 1 END) AS 'Mai'
,SUM(CASE WHEN MONTH(date) = 6 THEN 1 END) AS 'Juni'
,SUM(CASE WHEN MONTH(date) = 7 THEN 1 END) AS 'Juli'
,SUM(CASE WHEN MONTH(date) = 8 THEN 1 END) AS 'August'
,SUM(CASE WHEN MONTH(date) = 9 THEN 1 END) AS 'Sept'
,SUM(CASE WHEN MONTH(date) = 10 THEN 1 END) AS 'Okt'
,SUM(CASE WHEN MONTH(date) = 11 THEN 1 END) AS 'Nove'
,SUM(CASE WHEN MONTH(date) = 12 THEN 1 END) AS 'Desem'
,SUM(CASE WHEN YEAR(date) = 2006 THEN 1 END) AS 'TOTAL'
FROM table
WHERE YEAR(date) = 2006
GROUP BY type

This in combination with union the other 2 types results in what I'd like to do but then again, phuu this is some crappy approach :)

Any suggustions in how to solve this?
I.E I'd like to list each type count for each month like this

Jan Feb Mars ...
type1 23 43 45
type2 12 11 15
type3 54 55 65

Any hints?

Maybe something like?

set nocount on

Unfortunatly the types are 3 different columns (at design time this report was not considered).
To work around this I union these to one "alltypes" column. This is timeconsuming and I would prefere not to do so.

Part from that your approach works find (part from pivot, I'm on SQL server 2000, not a problem though).

Is there a workaround for the unions?

Thanks
