If you have an updatable view like
CREATE VIEW bar AS SELECT * FROM foo
you can edit rows in simple Browse mode, but when you have a WHERE clause like
SELECT * FROM
barWHEREID= 1
phpMyAdmin says "Current selection does not contain a unique column. Grid edit, checkbox, Edit, Copy and Delete features are not available."
