Agreed. ParameterCompiledValue is the one which should be considered to answer this question (as I got it and please correct me if I'm wrong).
With my earlier attempt it was giving "Pelle" in both attempts (may be because of my multiple runs of procedure before checking the xml. So now I dropped and created the proc and table again and checked the execution plan. And the xml gave me following in both attempts:
<ColumnReference Column="@Name" ParameterCompiledValue="'Kalle'" ParameterRuntimeValue="'Pelle'" />
So should the answer be "Kalle", "Kalle" instead of "Kalle", "Pelle" ?
or you tried asking what hsould be ParameterCompiledValue and ParameterRuntimeValue ?
Apologies but I'm just try to clear my doubt here. Interesting question though.
