如何查看mysql数据库版本

SHOW VARIABLES LIKE 'version';

<?php
$servername = "localhost";
$username = "your_username";
$password = "your_password";

// 创建连接
$conn = new mysqli($servername, $username, $password);

// 检测连接
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 获取版本信息
$sql = "SELECT VERSION()";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // 输出数据
    while($row = $result->fetch_assoc()) {
        echo "版本: " . $row["VERSION()"];
    }
} else {
    echo "0 结果";
}
$conn->close();
?>

import mysql.connector

mydb = mysql.connector.connect(
  host="localhost",
  user="your_username",
  password="your_password"
)

mycursor = mydb.cursor()
mycursor.execute("SELECT VERSION()")

myresult = mycursor.fetchone()

for x in myresult:
  print("MySQL 版本:", x)
