Informix Error -4068

Reasons / Common Causes

-4068 fires when the class::member double-colon syntax is used to invoke a member function that isn't SHARED — per the official guidance, only shared member functions can be called this way; normal member functions must be called through an object reference, since they need that reference as their SELF value.

1. A non-SHARED member function invoked via class::member syntax, per the official guidance — the direct, only cause.

Solutions / Resolution

1. Check that the class and member specified were the ones intended, per the official guidance.
2. Review the declaration of that class, per the official guidance — if the function genuinely needs to be called this way, declare it SHARED; otherwise call it through an object reference.

Examples

Calling a normal member function via ::

CALL Order::save()
-- -4068: save() is a normal member function, not SHARED

Corrected, calling through an object

DEFINE o Order
CALL o.save()

Diagnostic Checks

1. Check whether the called member function is declared SHARED, and either add SHARED or call it through an object reference instead.

class::member syntax was used on a non-SHARED member function — declare it SHARED, or call it through an object reference.
