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

The major distinguishing characteristics are the following:

  • The AS attribute_name list with an optional INSTANTIABLE specification.

    For CREATE TYPE (Distinct Form), the corresponding clause is the AS predefined_data_type clause.

  • The mandatory NOT FINAL specification.

    For CREATE TYPE (Distinct Form), the mandatory specification is FINAL.

  • The ability to create constructor method signatures, which you cannot do for distinct types.
