Informix Error -416

-416 USING option with open statement is invalid for insert cursor.

This OPEN statement refers to a cursor that was declared for an INSERT statement. The USING clause of the OPEN is not appropriate in this case; it is only used to specify the variables that are used with a SELECT statement. Review the program to ensure that the correct cursor has been used in this statement. If it has, and if the INSERT statement is written as part of the DECLARE statement, you can name the host variables directly in it. If the INSERT statement has been prepared, you can specify the host variables in a FROM clause in the PUT statement.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-416 fires when OPEN includes a USING clause for a cursor that was declared over an INSERT statement — USING on OPEN is only meaningful for SELECT-based cursors, where it supplies parameter values for the query. Insert cursors get their values through a different mechanism entirely.

  1. An OPEN ... USING clause applied to an insert cursor — the direct, only cause, usually from applying SELECT-cursor syntax patterns to an insert cursor by mistake.
  2. Confusing how parameter values are supplied for insert cursors versus select cursors — insert cursors take their values at PUT time (or inline in the DECLARE), not at OPEN time.
Solutions / Resolution
  1. For an inline INSERT in the DECLARE statement, name host variables directly in the VALUES clause, per the official guidance — no USING clause on OPEN is needed or valid.
  2. For a prepared INSERT statement, specify host variables in a FROM clause within the PUT statement, per the official guidance, rather than on OPEN.
  3. Remove the USING clause from OPEN entirely for any insert cursor — it never belongs there.
Examples
Inline INSERT cursor with host variables named directly
DECLARE curs1 CURSOR FOR
    INSERT INTO orders (order_id, customer_id) VALUES (:ord_id, :cust_id);
OPEN curs1;
PUT curs1;
Prepared INSERT cursor using PUT ... FROM
PREPARE stmt1 FROM 'INSERT INTO orders (order_id, customer_id) VALUES (?, ?)';
DECLARE curs1 CURSOR FOR stmt1;
OPEN curs1;
PUT curs1 FROM :ord_id, :cust_id;
The disallowed direct attempt
DECLARE curs1 CURSOR FOR INSERT INTO orders (order_id, customer_id) VALUES (?, ?);
OPEN curs1 USING :ord_id, :cust_id;
-- -416: USING on OPEN isn't valid for an insert cursor
Diagnostic Checks
  1. Confirm whether the cursor is declared over an INSERT or a SELECT — USING on OPEN only applies to the latter.
  2. Check where parameter values are actually being supplied for the insert cursor — they belong inline in DECLARE, or in PUT ... FROM, never in OPEN ... USING.
Related Errors / Related Topics
  • -413 — "Insert attempted on unopen cursor." A related insert-cursor lifecycle error, about open/close state rather than parameter-passing syntax.
  • -414 — "Insert attempted on NULL cursor." Another related insert-cursor error, about the cursor structure's validity rather than parameter-passing syntax.

Insert cursors take their values via inline DECLARE syntax or PUT ... FROM, never via OPEN ... USING — that clause is exclusively for select cursors.
