Informix Error -4500: A numeric conversion error has occurred due to incompatibility between a calling program and its function parameters or between a variable and its assigned expression.

Reasons / Common Causes

-4500 is a legacy code — per the official guidance, it has been replaced by error -1317. See -1317 for the current documentation of this condition: a data-type mismatch either between a function call's argument and its declared parameter type, or between an assignment's computed value and its target variable.

1. This exact wording is superseded, per the official guidance — -1317 now covers the same underlying condition.

Solutions / Resolution

1. Treat this as -1317 and apply that code's resolution steps, per the official guidance.

Examples

N/A

No triggering example is documented separately from -1317 — see that code for worked examples of the underlying numeric-conversion mismatch.

Diagnostic Checks

1. Confirm the environment/version reporting -4500 rather than -1317, and refer to -1317 for the actual diagnostic steps.
