Informix Error -4069

-4069 The type of expression on which member function "name" is

called is not a class.

This statement attempts to invoke the specified function using either the scope resolution (::) operator or the record membership (.) operator. However, the name to the left of the scope resolution operator is not the name of a class in which name is a member, or the name to the left of the record membership operator is not the name of an object reference of which name is a member. If you intended to call name through a reference to an object, use object.name syntax. Otherwise, make sure that you have specified the class and member names that you intended, and review the declaration of the class.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-4069 fires when a function call uses :: or . but the left-hand name isn't a valid class (for ::) or object reference (for .) that has that member — per the official guidance, if calling through an object was intended, use object.name syntax; otherwise check the class and member names.

  1. The name before :: isn't a class declaring that member, per the official guidance — the first named case.
  2. The name before . isn't an object reference that has that member, per the official guidance — the second named case.
Solutions / Resolution
  1. If calling through an object reference was intended, use object.name syntax, per the official guidance.
  2. Otherwise, check the class and member names intended, and review the class declaration, per the official guidance.
Examples
Calling through a plain variable, not an object
DEFINE qty INTEGER
CALL qty::validate()
-- -4069: qty is not a class or object reference
Corrected
DEFINE o Order
CALL o.validate()
Diagnostic Checks
  1. Check whether the name before ::/. is actually a class or object reference, and switch to object.name syntax if calling through an object was intended.
Related Errors / Related Topics
  • -4068 — "Function "class::member" has not been declared as SHARED." A related member-call error, about a valid class's member not being SHARED rather than the left-hand operand not being a class/object at all.
  • -4029 — "The type of expression on which member "name" is selected is not an object reference or record." A closely related error covering the same non-class/non-object condition for member selection rather than member function calls.

The expression before ::/. isn't a valid class or object reference — check the names, or switch to object.name syntax.
