Attribute Values Default Description

cascade Determines how changes to the parent entity

will affect the linked relation.

catalog The database catalog against which the queries

should apply.

collection-type The name of a UserCollectionType class describ-

ing the collection type to be used in place of the
defaults.

check

The SQL to create a multirow check constraint
for schema generation.

embed-xml true , false

When using XML relational persistence, indi-
cates whether the XML tree for the associated
entity itself, or only its identifier, will appear in
the generated XML tree.

fetch join , select

The mode in which the element will be retrieved
( outer-join , a series of select s, or a series of
subselect s). Only one member of the enclosing
class can be retrieved by outer-join .

lazy true , false

Can be used to disable or enable lazy fetching
against the enclosing mapping's default.

mutable true , false true

Can be used to flag that a class is mutable (allow-
ing Hibernate to make some performance opti-
mizations when dealing with these classes).

name The (mandatory) name of the attribute. This

should start with a lowercase letter.

node Specifies the name of the XML element or attrib-

ute that should be used by the XML relational
persistence features.

optimistic-lock true , false true

Specifies the optimistic locking strategy to use.

outer-join true , false ,

Specifies whether an outer join should be used.

auto

persister Allows a custom ClassPersister object to be

used when persisting this class.

schema The database schema against which queries

should apply.

subselect A query to enforce a subselection of the

contents of the underlying table. A class can
only use a subselect if it is immutable and read-
only (because the SQL defined here cannot be
reversed). Generally, the use of a database view
is preferable.

table The name of the table in which the associated

entity is stored.

where An arbitrary SQL where clause limiting the linked

entities.
