Informix Error -4501: A parameter count mismatch has occurred between the calling function and the called function.

Reasons / Common Causes

-4501 is a legacy code — per the official guidance, it has been replaced by error -1318. See -1318 for the current documentation of this condition: a function call supplying a different number of arguments than the called function's declared parameter list.

1. This exact wording is superseded, per the official guidance — -1318 now covers the same underlying condition.

Solutions / Resolution

1. Treat this as -1318 and apply that code's resolution steps, per the official guidance.

Examples

N/A

No triggering example is documented separately from -1318 — see that code for worked examples of the underlying parameter-count mismatch.
