GenerationType.AUTO - JPA enum constant

Enum Constant
javax.persistence.GenerationType
AUTO

Indicates that the persistence provider should pick an appropriate strategy for the particular database. The AUTO generation strategy may expect a database resource to exist, or it may attempt to create one. A vendor may provide documentation on how to create such resources in the event that it does not support schema generation or cannot create the schema resource at runtime.
