JavaEE學習筆記---數據庫操做篇

測試JDBC和SQLServer的插入操做,源碼以下:

 

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.Scanner;

/**

public class DBDemoInsert {
public static void main(String[] args) throws Exception{
String driver="com.microsoft.sqlserver.jdbc.SQLServerDriver";
Class.forName(driver);
/*
String url="jdbc:sqlserver://127.0.0.1:1433;database=ssh";
Connection con=DriverManager.getConnection(url,"sa","fyl360782");
*/
String url="jdbc:sqlserver://127.0.0.1:1433;database=ssh;user=*******;password=******";
Connection con=DriverManager.getConnection(url);

String sql="select * from subscriber";
Statement cmd=con.createStatement();
ResultSet rs=cmd.executeQuery(sql);

System.out.println("帳戶\t\t"+"密碼\t\t"+"暱稱\t\t"+"電話\t");
while(rs.next()){
String userid=rs.getString(1);
String pwd=rs.getString(2);
String name=rs.getString(3);
String phone=rs.getString(4);
System.out.println(userid+"\t\t"+pwd+"\t\t"+name+"\t\t"+phone);
}



String insertsql="insert into users(userid,pwd,name,phone) values(?,?,?,?)";
PreparedStatement insertcmd=con.prepareStatement(insertsql);

System.out.println("按照如右格式輸入數據,空格分隔,回車確認:"+"\t帳戶\t"+"密碼\t"+"暱稱\t"+"電話:");
Scanner reader=new Scanner(System.in);
System.out.println(reader.next()+"\t"+reader.next()+"\t"+reader.next()+"\t"+reader.next());

insertcmd.setString(1,"raisann");
insertcmd.setString(2,"asd");
insertcmd.setString(3,"らいさん");
insertcmd.setString(4,"6698258");

insertcmd.executeUpdate();
/*
insertcmd.setString(1,reader.next());
insertcmd.setString(2,reader.next());
insertcmd.setString(3,reader.next());
insertcmd.setString(4,reader.next());

insertcmd.executeUpdate();
*/
reader.close();
con.close();
}
}

 

 

進行數據庫Insert操做發生以下錯誤:

 

 

必應搜索後找到以下解決方案:

Thanks Mr. Normand for your continued efford to solve my problem. I have found the error..

In fact what mistake I was doing that I was searching for the class as usual in com.microsoft.sqlserver.jdbc . However in the error (that I attached) first line said 'java.lang.NoClassDefFoundError: microsoft/sql/DateTimeOffset'. It means It was trying to find the class in microsoft/sql directory. After creating the directory in my Classpath it worked.

There are only two classes under microsoft/sql viz. Types and DateTimeOffset. The reason best known to Microsoft only.
Now it is working. This may be helpful to others too. Further it works with SQLServer 2005 successfully.

Thanks..
