I'm interested in getting back JavaScript Date objects when I have a TIMESTAMP field. I've put together an example of what I'm trying to do here: https://observablehq.com/d/31ca79f19d6a70c1
is this something that could be supported?

Can you start a discussion on GitHub? One thing to check first is whether/how arrow supports date times since we use that for communication between the WASM and the JS contexts.

Getting a "RuntimeError: Failed to fetch" on all the DuckDB notebooks. Is there some network issue?

Can you please open the chrome developer console and check if an error is printed there?

"Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'self' 'sha256-nnRzvGsB15enSSxWufoVP+C4WOA6Spq28ybk2OobhJo=' https://static.observablehq.com https://www.google-analytics.com https://www.googleapis.com https://apis.google.com https://js.stripe.com". Either the 'unsafe-inline' keyword, a hash ('sha256-b6sJGgImaECb6xDFLCQENix+I0HKGZXyYl/wwqTc5QY='), or a nonce ('nonce-...') is required to enable inline execution."

I opened this page in incognito window and I don't see the error. Most likely this is due to some conflict with a plugin perhaps. I will look further and see if I can isolate the source of the error. Doesn't seem that this anything from your end.

Ok! Glad you found a workaround. Let me know if the problem persists!

If you run into anyone else with this issue my steps to resolve:
Disable all extensions.
Restart browser
Enable extensions back
== Problem gone :)

typo at the end of this block: `millions of start` -> `millions of stars`.

the link to the apache arrow table docs broke, it should be https://arrow.apache.org/docs/js/classes/Arrow_dom.Table.html

I added the following function to get a functional SQL Cell with parameters.

function par2query(query, params){   
  var out = query
  if (typeof params !== 'undefined'){
    for (let i = 0; i <params.length; i++) {
      out = out.replace('?',params[i]);
    }
  }
  return out
}

Thank you. I added proper support for prepared statements. Let's see how it performs.

how might we allow the user to specify header=true when using "of" with fileattachments?

We could allow an object with a file attachment? Or we could just not support it and expect people to use the insertCSV method.
