sql:
  adresses: https://static.data.gouv.fr/resources/bureaux-de-vote-et-adresses-de-leurs-electeurs/20230626-135723/table-adresses-reu.parquet
  quakes: https://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/all_day.csv
  gaia: https://uwdata.github.io/mosaic-datasets/data/gaia-5m.parquet

```sql echo
SELECT COUNT() FROM quakes;
```

etc.

closes #1071

I believe this is more a bugfix than a new feature (we previously returned /https:/static.data.gouv.fr/resources/burea……….parquet).

Not sure this is the right place to do this — normally we only call resolveFile on things that we know are files (unlike resolveImport, I guess). Look for calls to isAssetPath, which we should also use here. I’ll take a look and see if we can consolidate. Good find on the fix!

The caller is renderFiles

framework/src/render.ts

Line 96 in efd8ba0

function renderFiles(files: Iterable<string>, resolve: (name: string) => string, getLastModified): string {

called where we build the registerTable client code.

framework/src/render.ts

Line 66 in efd8ba0

}${data?.sql ? `\nimport {registerTable} from ${JSON.stringify(resolveImport("npm:@observablehq/duckdb"))};` : ""}${

Yeah, we don’t want to declare a FileAttachment with an external URL, I imagine. Interesting that it works though.

Switched to using the FROM-first syntax, e.g.,

CREATE TABLE 'quakes' AS FROM 'https://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/all_day.csv';
