Hey,

I'm trying to get canned inserts to work. I have an DB with following metadata:

```text sqlite> .mode line

sqlite> select name, sql from sqlite_master where name like '%search%'; name = search sql = CREATE TABLE "search" ("id" INTEGER NOT NULL PRIMARY KEY, "name" VARCHAR(255) NOT NULL, "url" VARCHAR(255) NOT NULL) ```

```yaml

...

queries: add_search: sql: insert into search(name, url) VALUES (:name, :url), write: true `` which renders a form as expected, but when I submit the form I getincomplete input` error.

but when submit post the form

I've attached a debugger to see where the error comes from, because incomplete input string doesn't appear in datasette codebase.

Inside datasette.database.Database.execute_write_fn

https://github.com/simonw/datasette/blob/4fa7cf68536628344356d3ef8c92c25c249067a0/datasette/database.py#L69

py result = await reply_queue.async_q.get()

this line raises an exception.

That led me to believe I had something wrong with my SQL. But running the command in sqlite3 inserts the record just fine.

text sqlite> insert into search (name, url) values ('my name', 'my url'); sqlite> SELECT last_insert_rowid(); last_insert_rowid() = 3

So I'm a bit lost here.
