Trino historical database not returning data. was created by michaelnicol

I am trying to interact with the Trino historical database to retrieve ADSB data between two times. I have the proper authentication token generation code, and below is the code designed to query Trino and then process the data.

The code below does a post request to

    var nextURI: string | undefined;
    const queryString = `SELECT * FROM ${startTimeEPOCHMS / 1000} AND ${endTimeEPOCHMS / 1000}`;
    const response = await (
      '',
      queryString,
      {
        headers: {
          Authorization: `Bearer ${}`,
          'Content-Type': 'text/plain',
        },
      }
    );
    if (response && == 200) {
      const body = ;
      nextURI = ;
      (200);
    } else {
      throw new Error('Unokay response whilst querying OpenSky');
    };
    if (nextURI) {
      while (nextURI) {
        await fetch(nextURI, {
          method: 'GET',
          headers: {
            'Authorization': `Bearer ${}`
          }
        }).then(async (response) => {
          if (response && ) {
            // Wait for the data to arrive.
            const responseData = await ();
            // Print the columns
            ((, undefined, 2))
            if (== "FINISHED" || == "FAILED") {
              nextURI = undefined;
            } else {
              // Go to the next URI.
              nextURI = 
            }
          }
        }).catch((error) => {
          throw error;
        });
      }
    } else {
      throw new Error("No nextUri received");
    }

When I run this code with the following query:

[code]SELECT * FROM

[/code]

It takes 7.46 minutes, uses 385 NextURL links, and returns no data. When I print the columns from the body of the request, I get the following format every time:

    "name": "hour",
    "type": "integer",
    "typeSignature": {
      "rawType": "integer",
      "arguments": []
    }
  }
]

How can I fix this? Why am I getting no data?

I don't know what this is. Anyway, I can't find any trace that you've requested and received access to the Trino database.

The research lab I work for is a contributor, and I use those credentials. I created this account so I could post on the forums.

The ID of a similar query to the one above is 20240613_220028_57242_jtdt5.

The post above appears to have considered the example query I posted as a link and removed it.

The query of the ID I just posted is:

SELECT * FROM

I started this query before submitting this reply; it's been running for 1.63 minutes with 0B output data.
