Async/Await가 Node.js MySQL 쿼리 결과를 어떻게 동기화할 수 있나요?

// Import required modules
const mysql = require('mysql');
const util = require('util');

// Create a MySQL connection
const conn = mysql.createConnection({/* connection parameters */});

// Promisify the query method using util.promisify().
// Remember to use .bind() to maintain the correct this context.
const query = util.promisify(conn.query).bind(conn);

// Execute queries concurrently using async/await
const main = async () => {
  try {
    const rows1 = await query(/* query string */);
    const rows2 = await query(/* query string */);
    const rows3 = await query(/* query string */);
    const rows4 = await query(/* query string */);

    // Append the results to a single string
    let appendedText = `${rows1} ${rows2} ${rows3} ${rows4}`;

    // Use the appendedText as needed
  } catch (err) {
    // Handle errors
  } finally {
    // Close the connection
    conn.end();
  }
};

// Start the process
main();
