  • Element Details

    • force

      boolean force
      If enabled, allowed discriminator values are always explicitly enumerated in select queries, even when retrieving all instances of a root entity and its subtypes. This is useful if there are discriminator column values which do not map to any subtype of the root entity type.

      This setting has the side effect of suppressing the generation of a check constraint in the DDL for the discriminator column.

      Returns:
      true if allowed discriminator values must always be explicitly enumerated
      Default:
      false

    • insert

      boolean insert
      Should be false if a discriminator column is also part of a mapped composite identifier, and should not be duplicated in SQL INSERT statements.
      Default:
      true
