javasqlserver代码

⑴ 求java链接sqlserver数据库的代码，以及配置

public class JDBConnect {
    //private static final String DRIVER="com.mysql.jdbc.Driver";
    private static final String DRIVER="com.microsoft.sqlserver.jdbc.SQLServerDriver";
    //private static final String URI="jdbc:mysql://localhost:3306/数据库名称";
    private static final String URI="jdbc:sqlserver://127.0.0.1:1433; DatabaseName=数据库名称";
    private static final String USER="sa";
    private static final String pwd="sasa";
    public static Connection getConnection(){
        Connection con=null;
        try{
            Class.forName(DRIVER);
        }catch(ClassNotFoundException e){
            System.out.println("加载驱动错误信息：" + e.getMessage());
        }
        try{
            con=DriverManager.getConnection(URI,USER,pwd);
        }catch(SQLException e){
            System.out.println("数据库连接错误信息：" + e.getMessage());
            e.printStackTrace();
        }
        return con;
    }
}

⑵ java程序连接sql server2008数据库:求给一个具体的代码，和过程。

连接数据库
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;

public class TestDB {

public static void main(String[] args) {
try {
// 1.注册驱动
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
System.out.println("注册驱动成功");

String url = ""jdbc:microsoft.sqlserver://127.0.0.1:1433;DatabaseName="; //数据库IP,端口,数据库名

String username = "";
String password = "";
// 加载驱动并获取数据库连接对象
Connection connection = DriverManager.getConnection(url, username,
password);
System.out.println("连接数据库成功！");
// 创建Statement对象
Statement stmt = connection.createStatement();
// SQL语句
String sql = "insert into student(id,name,age,email,address) values(1,'tom',23,'[email protected]','England') ";
int rows = stmt.executeUpdate(sql);
if (rows > 0) {
System.out.println("插入成功!");
}
// 释放资源
stmt.close();
connection.close();
} catch (SQLException e) {
e.printStackTrace();
}

catch (ClassNotFoundException e) {
e.printStackTrace();
}

}

}

预编译的数据库处理
public class ConnectionManager{
public static final String DRIVER_CLASS ="";
public static final String URL = "";
public static final String USERNAME = "";
public static final String PASSWORD = "";

//获取连接对象
public static Connection getConnection(){
Connection conn = null;
Class.forName(DRIVER_CLASS);
conn = DriverManager.getConnection(URL,USERNAME,PASSWORD);
return conn;
}
public static void closeAll(ResultSet rs,Statement stmt,Connection conn){
try{
if(rs!=null){
rs.close();
rs = null;
}
if(stmt!=null){
stmt.close();
stmt = null;
}
if(conn!=null){
conn.close();
conn=null;
}
}
}
}
public class DBOperator{
public int executeUpdate(String sql,Object[] params){
int rows = 0;
Connection connn = ConnectionManager.getConnection();
PreparedStatement pstmt = conn.prepareStatement(sql);
if(params!=null){
for(int i=0;i<params.length;i++){
pstmt.setObject(i+1,params[i]);//下标从1开始
}
}
rows = pstmt.executeUpdate();
ConnectionManager.closeAll(null,pstmt,conn);
return rows;
}
public ResultSet executeQuery(String sql,Object[] params){
Connetion conn = ConnectionManager.getConnection();
if(params!=null){
for(int i= 0;i<params.length;i++){
pstmt.setObject(i+1,params(i));
}
}
rs=pstmt.executeQuery();
ConnectionManager.closeAll(rs,pstmt,conn);
return rs;
}
}

/**
*statement连接数据库
*/

public class TestOperatorGrade{
private static void updateGrade(int id,String name,String description){
Class.forName();//注册驱动
Connection conn = DirverManager.getConnection("","","");
Statement stmt = conn.createStament();
String sql = "UPDATE grades set name = '"+name+"',description='"+description+"'WHere id="+id;
int rows = stmt.executeUpdate(sql);

}
}

这是java 程序的代码

⑶ java连接sqlserver数据库代码

<%
String sqlDriver="com.microsoft.sqlserver.jdbc.SQLServerDriver";
String url="jdbc:sqlserver://localhost:1433;DatabaseName=自己的数据库名字";
String user="用户名";
String password="密码";
Connection conn=null;
try{
Class.forName(sqlDriver).newInstance();
conn=DriverManager.getConnection(url,user,password);
// out.println("数据库加载成功");
}catch(Exception e){
// out.println("数据库加载出现错误！");
}
%>

⑷ java连接数据库的代码

package mysql;
import java.sql.*;

/**

* @author xys
*/
public class ConnectMysql {
public static Connection getConnection() throws ClassNotFoundException, SQLException {
String url = "jdbc:mysql://localhost:3306/databaseName";
String user = "mysqluser";
String password = "password";
String driverClass = "com.mysql.cj.jdbc.Driver";
Connection connection = null;
Class.forName(driverClass);
try {
connection = DriverManager.getConnection(url, user, password);
} catch (SQLException e) {
e.printStackTrace();
}
if (connection != null) {
System.out.println("数据库连接成功");
} else {
System.out.println("数据库连接失败");
connection.close();
}
return connection;
}

public void getResult() throws ClassNotFoundException, SQLException {
// 实例化 Statement 对象
Statement statement = getConnection().createStatement();
// 要执行的 Mysql 数据库操作语句（增、删、改、查）
String sql = "";
// 展开结果集数据库
ResultSet resultSet = statement.executeQuery(sql);
while (resultSet.next()) {
// 通过字段检索
int id = resultSet.getInt("id");
String name = resultSet.getString("name");

// 输出数据
System.out.println("ID : " +id);
System.out.println("name :" + name);
}
// 完成后需要依次关闭
resultSet.close();
statement.close();
getConnection().close();
}
}
