Informix Error -4063

-4063 Function "name" should not return any results.

This statement invokes the function "name" in a context that implies it should return one or more values. However, that function has been declared earlier in this module without a RETURNING clause or with RETURNING VOID. Make sure that you have called the function you intended; then review its declaration.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-4063 fires when a function is called in a context expecting a returned value, but the function was declared without a RETURNING clause (or with RETURNING VOID) — per the official guidance, this is a mismatch between the call's expectation and the function's own declaration.

A function called where a return value is expected, but it's declared VOID (or with no RETURNING clause), per the official guidance — the direct, only cause.

Solutions / Resolution

Make sure the function called was the one intended, per the official guidance.
Review the function's declaration to confirm whether it should return a value, per the official guidance.

Examples

Expecting a value from a VOID function

FUNCTION logEvent(msg CHAR(50))
  -- no RETURNING clause; implicitly VOID
END FUNCTION

LET x = logEvent("started")
-- -4063: logEvent() returns nothing

Corrected

CALL logEvent("started")

Diagnostic Checks

Check the function's RETURNING clause, and confirm the call site's expectations match it.
