sqlite: excess bound parameters produce an opaque "column index out of range" error

Version

v24.15.0 (also present on main)

Platform

Darwin 25.6.0 arm64 (platform-independent — pure BindParams logic)

Subsystem

sqlite

What steps will reproduce the bug?

const { DatabaseSync } = require('node:sqlite');
const db = new DatabaseSync(':memory:');
db.exec('CREATE TABLE t(a)');

const ins = db.prepare('INSERT INTO t VALUES (?)');
ins.run(1, 2);          // ERR_SQLITE_ERROR, errcode 25, "column index out of range"
db.prepare('SELECT 1').get(5);   // same

Any excess anonymous argument reproduces it, regardless of type — 2, 'x', and null all give the identical message.

How often does it reproduce? Is there a required condition?

Always, whenever the number of anonymous arguments exceeds the statement's sqlite3_bind_parameter_count().

What is the expected behavior? Why is that the expected behavior?

An error naming the actual problem — that more parameters were supplied than the statement accepts, ideally with both counts. Something like:

TypeError [ERR_INVALID_ARG_COUNT]: Statement accepts 1 parameter, but 2 were provided.

Two reasons this matters:

1. The message describes the wrong thing. "Column index out of range" is SQLite's wording for a binding index, but to a JS caller "column" reads as a table column, pointing them at their schema rather than their call site. Nothing in the message indicates an argument-count mismatch.

2. It's inconsistent with how the adjacent failure is reported. A wrong-type argument gets a precise Node-authored error: ERR_INVALID_ARG_TYPE: Provided value cannot be bound to SQLite parameter 2. A wrong-count argument falls through to a raw SQLite error code. Both are caller mistakes in the same call, caught in the same function.

What do you see instead?

ERR_SQLITE_ERROR with errcode: 25 and message column index out of range.

Additional information

The anonymous-binding loop in StatementSync::BindParams (src/node_sqlite.cc) iterates args from anon_start to args.Length() without comparing that span against sqlite3_bind_parameter_count(), so the overflow surfaces from sqlite3_bind_* instead. param_count is already fetched a few lines above, inside the bare-named-params block. A pre-loop guard would cover every excess-argument case at once.

Worth deciding up front whether this should throw at all, or ignore extra arguments the way ordinary JS functions do. Throwing seems better for a database API, and it's the current behavior, so a guard would preserve semantics while fixing only the message. Note this would be a breaking change for anyone matching on ERR_SQLITE_ERROR/errcode 25, so it likely wants semver-major treatment.

Surfaced while reviewing #62008, which changes undefined handling in the same function; the two are independent.

Inizia in src/node_sqlite.cc, in StatementSync::BindParams, esaminando la gestione esistente di param_count e il ciclo di binding anonimo. Riproduci il problema con gli snippet SQL forniti; il lavoro è completato quando gli argomenti anonimi in eccesso riportano un errore chiaro sul numero di parametri invece di SQLite errcode 25, senza modificare il comportamento di binding esistente.
