Similarities With The Syntax For CREATE TYPE (Distinct Form)

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.
