Generated sqlite query to update on conflict fails with missing param

What happened?

Using the schema and query to update a row on insertion conflict with the following Go test fails:

package db

import (
	"context"
	"database/sql"
	"os"
	"testing"
	"time"

	_ "modernc.org/sqlite"
)

func TestSavePin(t *testing.T) {
	_, err := os.Create("test.sqlite")
	if err != nil {
		t.Fatal(err.Error())
	}

	db, err := sql.Open("sqlite", "test.sqlite")
	if err != nil {
		t.Fatal(err.Error())
	}

	schema, err := os.ReadFile("../schema.sql")
	if err != nil {
		t.Fatal(err.Error())
	}

	_, err = db.Exec(string(schema))
	if err != nil {
		t.Fatal(err.Error())
	}

	q := New(db)

	pin, err := q.SavePin(context.Background(), SavePinParams{
		Title:     "title",
		Url:       sql.NullString{String: "url", Valid: true},
		ImageUrl:  sql.NullString{},
		CreatedAt: time.Now().UnixMilli(),
	})
	if err != nil {
		t.Fatal(err.Error())
	}
	_ = pin
}

The test fails with this output:

--- FAIL: TestSavePin (0.00s)
    query_test.go:43: missing argument with index 5
FAIL
FAIL    github.com/joeriddles/patina/server/db  0.521s

Relevant log output

Database schema

-- schema.sql
CREATE TABLE pins (
  id INTEGER PRIMARY KEY,
  title TEXT NOT NULL,
  url TEXT,
  image_url TEXT,
  created_at INTEGER NOT NULL
);

CREATE UNIQUE INDEX unique_url_idx ON pins (url);

SQL queries

-- name: SavePin :one
INSERT INTO pins (
  title, url, image_url, created_at
) VALUES (
  ?, ?, ?, ?
)
ON CONFLICT (url)
DO UPDATE SET title = ?, image_url = ?
RETURNING *;

Configuration

version: "2"
sql:
  - engine: "sqlite"
    schema: "schema.sql"
    queries: "query.sql"
    gen:
      go:
        package: "db"
        out: "db"

The generated query is missing two params. It should have six total.

func (q *Queries) SavePin(ctx context.Context, arg SavePinParams) (Pin, error) {
	row := q.db.QueryRowContext(ctx, savePin,
		arg.Title,
		arg.Url,
		arg.ImageUrl,
		arg.CreatedAt,
	)
	var i Pin
	err := row.Scan(
		&i.ID,
		&i.Title,
		&i.Url,
		&i.ImageUrl,
		&i.CreatedAt,
	)
	return i, err
}

Manually updating the generated query to the following fixes the error:

func (q *Queries) SavePin(ctx context.Context, arg SavePinParams) (Pin, error) {
	row := q.db.QueryRowContext(ctx, savePin,
		arg.Title,
		arg.Url,
		arg.ImageUrl,
		arg.CreatedAt,
		arg.Title,
		arg.ImageUrl,
	)
	var i Pin
	err := row.Scan(
		&i.ID,
		&i.Title,
		&i.Url,
		&i.ImageUrl,
		&i.CreatedAt,
	)
	return i, err
}

I forked and wrote a test that fails with the same error: https://github.com/joeriddles/sqlc/tree/joeriddles/3834

Using the excluded.<col_name> syntax does work: https://www.sqlite.org/lang_upsert.html#:~:text=%20to%20use%20the%20value%20that%20would%20have%20been%20inserted%20had%20the%20constraint%20not%20failed%2C%20add%20the%20special%20%22excluded.%22%20table%20qualifier%20to%20the%20column%20name.%20

/* name: SaveBook :one */
INSERT INTO books (
    author_id,
    isbn,
    book_type,
    title,
    yr,
    available,
    tag
) VALUES (
    ?,
    ?,
    ?,
    ?,
    ?,
    ?,
    ?
)
ON CONFLICT (isbn)
DO UPDATE SET author_id = excluded.author_id, book_type = excluded.book_type, title = excluded.title, yr = excluded.yr, available = excluded.available, tag = excluded.tag
RETURNING *;

Looks to be related to:

• name parameter not resolved in do statement #3439
• upsert with arg or narg doesn't work in sqlite3 #3508 ?

Debugging this... it looks like the OnConflictingCause field in the query's ast.Node is nil, when it should be populated.
