create or replace VIEW view_name (col1,col2, P_inputparam VARCHAR2)
as
SELECT Col1,Col2

Not like that... no.
What you're using as "input" there are SQL*Plus substitution variables. Those values are requested by SQL*Plus before the code is sent to the database and compiled. Code that runs on the database has no way of interacting with a client keyboard or screen, so you cannot get stored code to prompt for user input.
See: {message:id=10744582}
It's possible to use SYS_CONTEXT to get a view to pick up a value that has been previously assigned before the view is used, though I rarely find a need to do this myself.
