Except for SQL functions which can be inlined, the optimizer can't
optimize what is being done in the function with what is being done
in the select statement. This might be a performance issue depending
on your particular circumstances.

You should be able to have one view per table and use an OR in the where
clause to check for student, teacher or parent access. These tests
should be simple enough, that you should be able to just do the joins
in the view.
