FAQ: Can a Definition Query Be Applied to a Table without an ObjectID or Primary Key Field

Answer

An ObjectID or primary key field is required to perform any selection of features or records in the map. A definition query is a form of selection, and therefore cannot be conducted without the presence of a unique identifier, like a primary key field or an auto-number field.
