Dave,
The way you make it sound, the instance of the UDF that is run stays
in memory as long as there is a reference to the query that it
contains.
If I expanded the example to say that the UDF was a method of some
component and was being called with a cfinvoke, the same case would
apply. The component instance will stay in memory as long as a
reference to the query exists, even though the query should be local
to the UDF and nothing should be returned from the UDF.
You also use the term "go out of scope" which I take to mean "can no
longer be accessed, but still exists in memory". I assume this is
linked to my other question about the memory used by invoked
components being reused or not. If the memory is not reused, the
component stays in memory but is no longer accessible ('out of scope')
Rather useless questions, but...
Thanks. :)
