怎么检查mysql的版本信息

mysql --version

SELECT VERSION();

import mysql.connector

try:
    cnx = mysql.connector.connect(user='your_username', password='your_password',
                                  host='your_host', database='your_database')
    cursor = cnx.cursor()
    cursor.execute("SELECT VERSION()")
    version = cursor.fetchone()
    print("MySQL version: {}".format(version[0]))
except mysql.connector.Error as err:
    print("Something went wrong: {}".format(err))
finally:
    if cnx.is_connected():
        cursor.close()
        cnx.close()

const mysql = require('mysql');

const connection = mysql.createConnection({
  host     : 'your_host',
  user     : 'your_username',
  password : 'your_password',
  database : 'your_database'
});

connection.connect();

connection.query('SELECT VERSION()', (error, results, fields) => {
  if (error) throw error;
  console.log('MySQL version: ', results[0]['VERSION()']);
});

connection.end();
