Subject Does Firebird support column-based locking?
Author cbmrussn
Is it possible to have specific permissions on specific columns in a
table, based on another column?

For example, if I have ATable with FieldOne, FieldTwo and LockField,
can I lock FieldTwo to read-only if LockField has a secific value,
through the FireBird engine?

Reading through the documentation, this doesn't appear possible, but
I would think that it could be possible.
