Session parameter

Question

Hello all!
I would like to know if there is any kind of session parameter that could be filled with user information, and later be used in a view. I will detail it below.
I would like to bind a view object to a client provided information. Something like this (ignore no matching syntax):
CREATE VIEW v AS
SELECT *
FROM mytable
WHERE
tableinfo = :user_provided_paramter
After connecting, the user should provide the parameter value (ignore no matching syntax, I'm wondering):
SET :user_provided_parameter = 'myinfo'
And the view would be sensible to this setting.
Any ideas?

What is:
The manner/application the user is connecting with (i.e., SQL*Plus, PL/SQL Gateway, Forms, etc.).
The nature of information you want to capture and persist (i.e., passive like client IP address, or interactive like their favorite color).
The length of time you need to persist things (i.e., between sessions or not)
The database version you are using.
