Help with sql query

Hi,

Can anyone please suggest a query I could use to extract all customers in the following sample table who have products "standard", "variable" and "offset" (all 3 products)?

Table: Client

Client_Id.....Product
--------.....--------
1...............Standard
1...............Variable
1...............Offset
2...............Redraw
2...............Interest
3...............Principal
...

Thanks.

One way:

Code:

select distinct client_id 
from client a
where 
exists (select 'X' from client b where a.client_id=b.client_id and product='Standard') 
and
exists (select 'X' from client b where a.client_id=b.client_id and product='Offset') 
and
exists (select 'X' from client b where a.client_id=b.client_id and product='Variable') ;
