javasqlserver代碼

⑴ 求java鏈接sqlserver資料庫的代碼，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/資料庫名稱";
    private static final String URI="jdbc:sqlserver://127.0.0.1:1433; DatabaseName=資料庫名稱";
    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("載入驅動錯誤信息：" + e.getMessage());
        }
        try{
            con=DriverManager.getConnection(URI,USER,pwd);
        }catch(SQLException e){
            System.out.println("資料庫連接錯誤信息：" + e.getMessage());
            e.printStackTrace();
        }
        return con;
    }
}

⑵ java程序連接sql server2008資料庫:求給一個具體的代碼，和過程。

連接資料庫
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.注冊驅動
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
System.out.println("注冊驅動成功");

String url = ""jdbc:microsoft.sqlserver://127.0.0.1:1433;DatabaseName="; //資料庫IP,埠,資料庫名

String username = "";
String password = "";
// 載入驅動並獲取資料庫連接對象
Connection connection = DriverManager.getConnection(url, username,
password);
System.out.println("連接資料庫成功！");
// 創建Statement對象
Statement stmt = connection.createStatement();
// SQL語句
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!");
}
// 釋放資源
stmt.close();
connection.close();
} catch (SQLException e) {
e.printStackTrace();
}

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

}

}

預編譯的資料庫處理
public class ConnectionManager{
public static final String DRIVER_CLASS ="";
public static final String URL = "";
public static final String USERNAME = "";
public static final String PASSWORD = "";

//獲取連接對象
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]);//下標從1開始
}
}
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連接資料庫
*/

public class TestOperatorGrade{
private static void updateGrade(int id,String name,String description){
Class.forName();//注冊驅動
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);

}
}

這是java 程序的代碼

⑶ java連接sqlserver資料庫代碼

<%
String sqlDriver="com.microsoft.sqlserver.jdbc.SQLServerDriver";
String url="jdbc:sqlserver://localhost:1433;DatabaseName=自己的資料庫名字";
String user="用戶名";
String password="密碼";
Connection conn=null;
try{
Class.forName(sqlDriver).newInstance();
conn=DriverManager.getConnection(url,user,password);
// out.println("資料庫載入成功");
}catch(Exception e){
// out.println("資料庫載入出現錯誤！");
}
%>

⑷ java連接資料庫的代碼

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("資料庫連接成功");
} else {
System.out.println("資料庫連接失敗");
connection.close();
}
return connection;
}

public void getResult() throws ClassNotFoundException, SQLException {
// 實例化 Statement 對象
Statement statement = getConnection().createStatement();
// 要執行的 Mysql 資料庫操作語句（增、刪、改、查）
String sql = "";
// 展開結果集資料庫
ResultSet resultSet = statement.executeQuery(sql);
while (resultSet.next()) {
// 通過欄位檢索
int id = resultSet.getInt("id");
String name = resultSet.getString("name");

// 輸出數據
System.out.println("ID : " +id);
System.out.println("name :" + name);
}
// 完成後需要依次關閉
resultSet.close();
statement.close();
getConnection().close();
}
}
