Identifing the source of a view column

Hello,

Does anyone know a script to select the source column for a view column.

For example:

create view v1 (f1, f2)
as select t1.f2, t2.f2
from t1,t2
where t1.f1=t2.f1;

When I want the know the source for v1.f1 the script or function should return
t1.f2.

Thanks,
