Hi All,

I've got a problem with some results processing - it looks kind of
familar, but I can't remember if we understand it, or have ever done
anything about it...

I'm executing a statement, which is "exec stored_procedure...."
The stored procedure is quite complex, but *should* have no result set.
My subsequent dblibrary calls to handle the results are tailored to that
expectation.

In *some* cases (I cant figure out why, but it might be something to do
with the "duplicate key was ignored..."), 
a phantom result set appears in the resulting TDS packet, viz:

The result set describes a one column result set, with no column name.
followed by a DONEINPROC token (which shouldn't be here as the stored
proc has SET NOCOUNT ON....)

This badly skews my program. 
I have a *vague* recollection of dealing with this before, but it's too
long ago now...

can anyone remember this ?
