Informix Error -4503: A function has not returned the correct number of values expected by the calling function.

Reasons / Common Causes

-4503 is a legacy code — per the official guidance, it has been replaced by error -1320. See -1320 for the current documentation of this condition: a function's RETURN statement supplies a different number of values than the caller expects to receive.

1. This exact wording is superseded, per the official guidance — -1320 now covers the same underlying condition.

Solutions / Resolution

1. Treat this as -1320 and apply that code's resolution steps, per the official guidance.

Examples
