Method Signatures

Unlike other SQL database objects, the definition for a method is split between CREATE METHOD (see “CREATE METHOD” on page 403) 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
  • Note that the RETURNS clause is defined both in the CREATE METHOD definition and in the CREATE TYPE signature for the method.
