Routine signature

Because routines can be overloaded and have duplicate names, the database server uniquely identifies an overloaded routine by its signature.

The routine signature includes the following information:
  • The type of routine (procedure or function)
  • The routine name
  • The number of parameters
  • The data types of the parameters
  • The order of the parameters
  • The owner name (ANSI database only)

For more information about routine signatures, see the Informix® User-Defined Routines and Data Types Developer's Guide.
