The syntax for CREATE TYPE (Distinct Form) is similar to that for the CREATE TYPE (Structured Form) statement.

The major distinguishing characteristics for distinct types are the following:

  • The AS predefined_data_type clause.

    For CREATE TYPE (Structured Form), the corresponding clause is AS attribute_name list with an optional INSTANTIABLE specification.

  • The mandatory FINAL specification.
  • The inability to create a user-defined constructor method signature for a distinct type.

    Structured UDTs allow you to define constructor method signatures.
