Question : Multiple counts on 1 column

I have seen this post: http://www.experts-exchange.com/Microsoft/Development/MS-SQL-Server/SQL-Server-2005/Q_22528773.html?sfQueryTermInfo=1+1+10+30+column+count+multipl+sql

but I think my question is different because I want the end result to display the counts in different columns when I used the examples in the post above it displays the results in rows.

I tried the attached code syntax but it didnt work for me - err with prefixes

I am using SQL 2000

Example:
I have 2 tables table A and table B below

--------------------------------------
Table A

ClientID ClientStartDate
1 1/1/2001
2 1/2/2001
3 3/5/2003
4 5/6/2002
5 4/7/2007

--------------------------------------
Table B

ClientID AccountDate ProductCode
1 2/2/2002 abc
1 5/6/2003 cde
1 6/6/2006 cde
2 1/2/2001 cde
3 3/5/2003 abc
3 5/8/2004 fgh
4 5/7/2003 abc
5 8/7/2007 abc

SQL Query:
need a count for each ProductCode

so the result should look something like this:
----------------------------------------------------------------------------------------------
ClientID abc cde fgh
----------------------------------------------------------------------------------------------
1 1 2
2 1
3 1 1

         
           
           
          Select T1.Column1 ,T1.c1 , T2.c2 from
(
select column1, count(*) as c1
from tbl_1
Where Column1 ='a'
Group By Column1
) T1
JOIN
(select column1, count(*) as c2
from tbl_1
Where Column1 ='B'
Group By Column1
) T2 ON T1.column1 = T2.Column1

Answer : Multiple counts on 1 column

Something like this?
If you knew the product codes beforehand.

select A.ClientID,
sum(case when B.ProductCode = 'abc' then 1 end) abc,
sum(case when B.ProductCode = 'cde' then 1 end) cde,
sum(case when B.ProductCode = 'fgh' then 1 end) fgh
from TableA A
left join tableB B on A.ClientID = B.ClientID
group by A.ClientID
