MySQL是一種關(guān)系型數(shù)據(jù)庫(kù)管理系統(tǒng)(RDBMS)，它可以用多種編程語(yǔ)言進(jìn)行訪問(wèn)和操作。

下面是使用不同編程語(yǔ)言連接MySQL數(shù)據(jù)庫(kù)的示例：

// 在PHP中連接MySQL數(shù)據(jù)庫(kù)
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
// 在Python中連接MySQL數(shù)據(jù)庫(kù)
import mysql.connector
mydb = mysql.connector.connect(
host="localhost",
user="username",
password="password",
database="mydatabase"
)
print(mydb)
// 在Java中連接MySQL數(shù)據(jù)庫(kù)
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class mysqlDemo {
public static void main(String[] args) {
Connection conn = null;
try {
// 數(shù)據(jù)庫(kù)驅(qū)動(dòng)
Class.forName("com.mysql.jdbc.Driver");
// 數(shù)據(jù)庫(kù)地址、用戶名、密碼
String url = "jdbc:mysql://localhost:3306/myDB";
String user = "username";
String password = "password";
// 建立連接并返回Connection對(duì)象
conn = DriverManager.getConnection(url, user, password);
System.out.println("Connection success!");
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
}
}

以上是幾種常見的編程語(yǔ)言連接MySQL數(shù)據(jù)庫(kù)的示例，開發(fā)人員可以根據(jù)自己的需求選擇合適的編程語(yǔ)言來(lái)連接操作MySQL數(shù)據(jù)庫(kù)。
