摘要：
1.下载jdbc：下载适用于SQLServer|MicrosoftDocs的jdbc驱动程序2.提取jdbc的内容：3.将jar包导入eclipse输入代码，然后运行：packagetest；importjava.sql。联系importjava.sql。驾驶员管理器；importjava.sql。结果集；导入java.sql.sql
1.下载jdbc：Download - JDBC Driver for SQL Server | Microsoft Docs
2.提取jdbc的内容：
3.导入jar包到eclipse
输入代码，运行：
package test;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class cc {
public static void main(String[] args) throws ClassNotFoundException, SQLException {
// TODO Auto-generated method stub
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String connectionUrl = "jdbc:sqlserver://localhost:1433;databaseName=AA;user=sa;password=123456;";
Connection conn = DriverManager.getConnection(connectionUrl);
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM test");
//如果有数据，rs.next()返回true
while(rs.next()){
System.out.println(rs.getString("ID")+" 年龄："+rs.getInt("value"));
}
}
}
