You can not make it not-null (your "not null" was ignored.).<div>We just thought it is no reason to have not-nullable text/blob/picture fields. Internally, empty data takes one blob-segment but null-data takes zero segments. On the other hand "not null" is sort of constraint which can be required by your business logic. Probably we have to allow not-nullable BLOBs...</div><div><br><div apple-content-edited="true">
