Обсуждение: Connection local variables?

Is there a way to create a variable specific to the current working
connection? Like a connection context or some such? I'm trying to take a
variable in a query, and allow it to be used by a rule.

Thanks,
Steve

You can create functions in a language that allows global storage.
Search in the archives for "app_session tcl" for examples of what I use.
