Cause and resolution
The statement must be closed before it can be reopened or executed.

Oninit® Troubleshooting Guidance
Reasons / Common Causes
-7443 fires when mi_open_prepared_statement or mi_exec_prepare_statement is called
against a prepared statement that's already open — per the official guidance.
- A prepared statement reopened or executed while already open, per the official guidance — the direct, only cause.
Solutions / Resolution
- Close the statement before reopening it (
mi_open_prepared_statement) or executing it (mi_exec_prepare_statement), per the official guidance.
Examples
Reopening an already-open statement
mi_open_prepared_statement(conn, stmt, ...);
mi_open_prepared_statement(conn, stmt, ...);
/* -7443: stmt is already open */
Diagnostic Checks
- Check the call sequence for the statement handle, and confirm it's closed before being reopened or executed again.
