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 HCL Informix® User-Defined Routines and Data Types Developer's Guide.
