Hi,

I'm using the ADO.NET with C#. When I perform an SQL query on a table in which the primary key consists of multiple fields and the SQL query is done on fewer fields than the primary key I get an exception.
("No value given for one or more required parameters")
I get why this may not be allowed, but I could to this in the old ADO.
(let's say I want all the x's of y, then y & x consist of the primary key, but I still need to create a query that returns all the x's of a certain y)

Does anybody know if they changed that? or do I need to do something else.

Thanks!
