Name of the structured UDT to be created.

For information about naming database objects, see SQL Fundamentals, B035-1141.

If the UDF library for your database contains any objects with multibyte characters in their name, you cannot use a single-byte session character set to create a new UDF, UDT, method, or Java stored procedure object even if the new object name contains only single-byte characters. Otherwise, the system returns an error to the requestor. Instead, use a multibyte session character set.

See SQL Fundamentals, B035-1141 for the rules for naming database objects.

Note that the creation of a structured type consumes two names in the TVMNameI name space for SYSUDTLIB:

  • The first name consumed corresponds to the name of the UDT itself.
  • The second name corresponds to the system-generated constructor function for the UDT.

    The system constructs this name as explained in the topic on naming conventions.

SYSUDTLIB
The containing database for UDT_name. If omitted, the containing database is SYSUDTLIB.
You cannot create a UDF within the SYSUDTLIB database with the same specific name or same routine signature.
If such a UDF already exists in SYSUDTLIB at the time you submit a CREATE TYPE request, the request fails because a routine with the same signature already exists.
