Unlike other SQL database objects, the definition for a method is split between CREATE METHOD and its signature as defined in its associated CREATE TYPE statement.

Although the definition for a method is generally similar to that of a UDF, unlike a UDF definition, the following components of a method are defined only in its signature:
  • SPECIFIC NAME clause
  • LANGUAGE clause
  • PARAMETER STYLE clause
  • [NOT] DETERMINISTIC clause
  • SQL data access (NO SQL) clause

The RETURNS clause is defined both in the CREATE METHOD definition and in the CREATE TYPE signature for the method.
