如何通过NodeJs API调用设置数据库名称

const mysql = require('mysql');

const connection = mysql.createConnection({
  host: 'localhost',
  user: 'root',
  password: 'password',
  database: 'mydatabase'
});

connection.connect((err) => {
  if (err) {
    console.error('Error connecting to database: ' + err.stack);
    return;
  }
  console.log('Connected to database as id ' + connection.threadId);
});

const sql = 'ALTER DATABASE mydatabase CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci';
connection.query(sql, (err, result) => {
  if (err) {
    console.error('Error setting database name: ' + err.stack);
    return;
  }
  console.log('Database name set successfully.');
});

connection.end((err) => {
  if (err) {
    console.error('Error closing database connection: ' + err.stack);
    return;
  }
  console.log('Database connection closed.');
});
