Hey all,
Is there way to determine a table column referenced by
a view column via SQL?
I want to create an universal function to determine
mandatoriness of some column of the view (i.e.
check the not null constraint of underlying table column).
note that a view column can be the result of a function or operation,
perhaps on fields of several columns from several tables being joined in
the view. how would your function cope with something like this?
