issues

I believe this is related to https://github.com/simonw/sqlite-utils/issues/98.

When pk is specified by table A's insert call, it throws an index error if a different table has written a row with a higher rowid than exists in the first table. Here's a basic example:

```py from sqlite_utils import Database

def test_pk_for_insert(fresh_db): user = {"id": "abc", "name": "david"}

fresh_db["users"].insert(user, pk="id")

fresh_db["comments"].insert_all(
    [
        {"id": "def", "text": "ok"},
        {"id": "ghi", "text": "great"},
    ],
)

fresh_db["users"].insert(
    user,
    ignore=True,
    # BUG: when specifying pk on the second insert call 
    # db.py goes into a block it doesn't expect and we get the error
    pk="id",
)

if name == "main": db = Database("bug.db") if db["users"].exists(): raise ValueError( "bug only shows on a new database - remove bug.db before running the script" ) test_pk_for_insert(db) ```

The error is:

py File "/Users/david/projects/reddit-to-sqlite/.venv/lib/python3.11/site-packages/sqlite_utils/db.py", line 2960, in insert_chunk row = list(self.rows_where("rowid = ?", [self.last_rowid]))[0] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^ IndexError: list index out of range

The issue is in this block:

https://github.com/simonw/sqlite-utils/blob/2747257a3334d55e890b40ec58fada57ae8cfbfd/sqlite_utils/db.py#L2954-L2958

relevant locals are:

• pk: 'id'
• result.lastrowid: 2

What's most interesting is the comment # self.last_rowid will be 0 if a "INSERT OR IGNORE" happened, which doesn't seem to be the case here.

I added a virtual column (no storage overhead) to the output that easily links back to the source. It works nicely out of the box with datasette:

I got bit a bit by https://github.com/simonw/sqlite-utils/issues/411, so I went with a manual table_xinfo and creating the table via execute. Happy to adjust if that issue moves, but this seems like it works.

I also added my best-guess instructions for local development on this package. I'm shooting in the dark, so feel free to replace with how you work on it locally.
