```

This appears to be because `db.upsert_all` is called with no rows -- I think? 

I hacked around this by modifying `import_from_file` to have an `if rows:` clause:

```
    for table, rows in to_insert.items():
        if rows:
            table_name = ""archive_{}"".format(table.replace(""-"", ""_""))
            ...
```

I'm happy to work up a real PR if that's the right approach, but I'm not sure it is.",206156866,issue,,,"{""url"": ""https://api.github.com/repos/dogsheep/twitter-to-sqlite/issues/29/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed

This appears to be because https://github.com/dogsheep/twitter-to-sqlite/blob/master/twitter_to_sqlite/cli.py#L111 calls `transform_user`, and then https://github.com/dogsheep/twitter-to-sqlite/blob/master/twitter_to_sqlite/cli.py#L116 calls `transform_user` again, which fails because the user is already transformed.

I was able to work around this by commenting out https://github.com/dogsheep/twitter-to-sqlite/blob/master/twitter_to_sqlite/cli.py#L116. 

Shall I work up a patch for that, or is there a better approach?",206156866,issue,,,"{""url"": ""https://api.github.com/repos/dogsheep/twitter-to-sqlite/issues/30/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed
