Informix Error -769: Internal - iterator execution/phase error parameter.

Reasons / Common Causes

-769 is flagged by the official text as an internal error in the execution of an iterator (a row-producing routine or query-execution mechanism operating in phases), with no documented application-level trigger.

1. A genuine internal engine condition during iterator execution, per the official guidance's framing, with no other documented application-level cause.
2. An iterator table function or a RETURN ... WITH RESUME routine hitting an unusual execution-phase transition, plausible given the "iterator execution/phase" framing, though not explicitly named by the sparse official text.

Solutions / Resolution

1. If you cannot find a direct cause, note all circumstances and contact IBM Informix Technical Support, per the official guidance — there is no documented general application-level fix.
2. Check whether an iterator table function or a WITH RESUME routine was involved in the failing statement, given the error's specific "iterator" framing, and capture that detail for escalation.
3. Try simplifying the statement or routine as a practical first step, if an unusual iterator-based construct was involved.

Examples

Capturing circumstances for escalation

-- Record whether an iterator table function or a RETURN ... WITH RESUME
-- routine was involved, and the exact statement in progress, for
-- escalation.

Diagnostic Checks

1. Check whether an iterator table function or WITH RESUME routine was involved.
2. Capture the exact statement/operation in progress for escalation.
