Internally, this calls [`sqlite3_reset`](https://www.sqlite.org/capi3ref.html#sqlite3_reset) followed by [`sqlite3_step`](https://www.sqlite.org/capi3ref.html#sqlite3_step) until it no longer returns `SQLITE_ROW`. If the query returns no rows, `undefined` is returned.

Use the "RETURNING" SQL statement and `get()` when inserting a record to grab the last inserted row id.

```ts
const insertStatement = "INSERT INTO foo (greeting) VALUES ($greeting) RETURNING id;"
const insertQuery = db.query(insertStatement, { $greeting: "Welcome to Bun!" });
console.log(await insertQuery.get());
// Output: { id: 1 }
```

### `.run()`

Use `.run()` to run a query and get back `undefined`. This is useful for schema-modifying queries (e.g. `CREATE TABLE`) or bulk write operations.
