### Joining a table with multiple foreign keys using `ON` SQL behavior

```typescript

import { createClient } from "@supabase/supabase-js";

// Initialize the Supabase client

const supabaseUrl = "YOUR_SUPABASE_URL";

const supabaseKey = "YOUR_SUPABASE_KEY";

const supabase = createClient(supabaseUrl, supabaseKey);

async function fetchAttendanceWithScansAndFlatten() {

  const { data, error } = await supabase.from("attendance").select(`

      *,

      scans:scan_id_start!inner (

        timestamp

      )

    `); // Using !inner to ensure we only get records with a matching scan

  if (error) {

    console.error(error);

    return;

  }

  // Map the results to include scans.timestamp at the same level as attendance data

  const flattenedData = data?.map((item) => ({

    ...item,

    scan_timestamp: item.scans?.timestamp,

    scans: undefined, // Optional: remove the scans object if you don't need it anymore

  }));

  return flattenedData;

}

// Call the function to fetch and process the data

fetchAttendanceWithScansAndFlatten().then((data) => {

  console.log(data);

});
