Re:So, you have an input parameter named "session_id" and a query with
a column named "session_id" - this is the problem.
Well, I'll re-try with a revised function, but surely the database
could have come up with a more meaningful and insightful message than
the coded incomprehensible error message it did ? I would say its
not only user error, its developer error too for creating such
confusing error messages !
