Informix Error -4150: First parameter must be an ixRow object.

Cause and resolution

First parameter must be an ixRow object.

For calls to the built-in functions packrow() and unpackrow(), the first argument must be of type ixRow.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-4150 fires when the built-in functions packrow() or unpackrow() are called with a first argument that isn't of type ixRow — per the official guidance, this is a strict requirement for both functions.

  1. packrow() or unpackrow() called with a first argument that isn't an ixRow object, per the official guidance — the direct, only cause.
Solutions / Resolution
  1. Pass an ixRow object as the first argument to packrow()/unpackrow().
Examples
An incorrect first argument type
CALL packrow(rec, ...)
-- -4150: rec must be an ixRow object, not a plain RECORD
Corrected
DEFINE r ixRow
CALL packrow(r, ...)
Diagnostic Checks
  1. Check the first argument of every packrow()/unpackrow() call, and confirm it's declared as ixRow.
