PrimaryJoinColumnAttribute Class

Defines the primary key column of a child table that references the parent table's primary key in a joined-tables inheritance strategy.

Remarks

Apply this attribute to each descendant class when using the joined-tables inheritance strategy. The named column is both the primary key of the child table and a foreign key referencing the corresponding column in the parent table. If omitted, the same column name as the parent table's primary key is used. When the ancestor has a composite identifier, one PrimaryJoinColumn can be specified per primary key column.
