According to The Adobe LiveDocs, dbvarname is now ignored.
"Changed the dbvarname attribute behavior: it is now ignored
for all drivers."
It seems to me that it should ignore it then, instead of
erroring. I just tried adding dbvarname to a cfstoredproc on my
Oracle 10g server with CF8 and received the error:
"The dbvarname attribute, if used, must be present with each
cfprocparam tag of the stored procedure."
So it seems to me, that if you use it, its all or nothing. I
don;t use it at all in my cfprocparams and everything works fine,
as long as I pass in the Vars in the right order.
