Informix Error -4025: Function "name" is already declared in the class.

Reasons / Common Causes

-4025 fires when a function with the same name is declared more than once in the same class — per the official guidance, a function of the specified name has already been declared in the current class.

1. The same function name declared twice within one class, per the official guidance — the direct, only cause.

Solutions / Resolution

1. Remove the duplicate declaration, or rename one of the two functions.

Examples

A duplicate function declaration

CLASS Order
  FUNCTION save()
    ...
  END FUNCTION

  FUNCTION save()
    -- -4025: save() is already declared above
  END FUNCTION
END CLASS

Corrected

CLASS Order
  FUNCTION save()
    ...
  END FUNCTION
END CLASS

Diagnostic Checks

1. Check the class for more than one declaration of the same function name, and remove or rename the duplicate.
