Any decent tutorials on creating pointers to copies of structures and
why/how to use the duplicate() function. I occasionally read about this
on this listserve and I cannot figure out what you guys are talking
about.
Thanks in advance.

Unofficially, assign your application/session variables to variable
scope
variables and use these instead in your database read/writes.
This way your lock is only for a fraction of a section while you
temporarily
reassign your variables and not for the entire time that your query is
talking to the webserver and database server...
Someone correct me if I'm wrong, but don't forget to duplicate() any
structures, otherwise if you do :
<cfset variables.mystruct = session.mysessionstruct>
all you do is create a pointer to your session structure and not a
second
copy of the structure. If you're only creating a pointer then you when
you
access that pointer you will also access the session or application
variable....
Well hope that helps...

Stephen
