@original and stored procedures

When using @.original_{0}, how does this work if you are using a stored procedure instead of inline SQL? For example, if my update parameters are like this :

<

UpdateParameters><asp:ParameterType="String"Name="ProductType"/><asp:ParameterType="String"Name="OpportunityType"/><asp:ParameterType="Double"Name="Value"/><asp:ParameterType="String"Name="Probability"/><asp:ParameterType="Int32"Name="OpportunityID"/></UpdateParameters>

And my stored procedure like this :

CREATE procedure dbo.UpdateOpportunity

(
@.ProductType int,
@.OpportunityType int,
@.Value money,
@.Probability int,
@.OpportunityID int
)

as

update Opportunity
set ProductType = @.ProductType, OpportunityType = @.OpportunityType,
[Value] = @.Value, Probability = @.Probability
where OpportunityID = @.OpportunityID

Do I need to change both cases of @.OpportunityID in my stored procedure to @.original_OpportunityID for it to work?

Most likely. It also depends on what you have set for the conflictdetection property. If it's compareallvalues, then you'll need to accept @.original_ for each of the columns that you selected via your select statement.
