Dynamic way to turn rows (which are already in cross-tab format) into columns?

The recordset I have is like this:
Date      Type            North_Cnt       West_Cnt
5/1/09     A                 20                  30  
5/1/09     B                 40                  25
5/2/09     A                30                  20
5/2/09     B                35                  45
...
I want to turn it into this way:
Date      Type    North_Cnt   West_Cnt    Date     Type  North_Cnt     West_Cnt
5/1/09     A             20                30         5/2/09     A          30                  20
5/1/09     B             40                25         5/2/09     B           35                 45

so if there are 10 dates then there will be 10 sections each of which has 4 columns (date, type, North_cnt, West_cnt) so totally 40 columns.

I want to try Pivot in 2005 but doubt it would work. I guess the only way is to use dynamic sql?
Has anyone done something similar like this before?

One of our local hot shots here at EE wrote an article on doing dynamic pivots.

Take a look at this:

Thanks! This is a very helpful article, the only problem is that it can only have one pivot_value_column in the aggregate. it doesn't do both sum(Tcs_quantity) and sum(tcs_quantity) together in the same pivot in the example, but this function is what i need.

I haven't worked with PIVOT a lot, but I'll assume that "sum(Tcs_quantity) and sum(tcs_quantity)" are acutally two different columns.  You MAY need to do two pivot statements.  Or two whole selects, built as derived tables, then joined together.

actually since my recordset is already in pivot format i'm looking for something like this:
select * from
(
select * from myTable
where date=5/1/09'
) a
join
(
select * from myTable
where date=5/2/09'
) b
on a.type=b.type

and make it dynamic:
declare @min datetime
select @min = min(date) from myTable

declare @max datetime
select @max=max(date) from myTable

declare @sql varchar(max)
select @sql = 'SELECT * from (select * from myTable where date=, ' + CHAR(13),

while @min<=@max
begin
SET @sql = @sql + ''

SET @min = @min + 7 ;

end

Yes I can do it that way and that's the only way to do it if using pivot, but I was just trying to avoid two or multiple pivot statements as I have 4 columns which i need to do aggregation on. That's why i was thinking about other ways in dynamic sql.

Thanks!
