Finding Duplicates with SQL

Here's a query for finding duplicates in a table.

SELECT id_company,
  COUNT(id_company) AS occurrences
FROM company
GROUP BY id_company
HAVING ( COUNT(id_company) > 1 )

You could also use this technique to find rows that occur exactly once as bellow

SELECT id_company
FROM company
GROUP BY id_company
HAVING ( COUNT(id_company) = 1 )

How to Create Auto Increment Columns in Oracle

CREATE TABLE test_table
(
ID NUMBER NOT NULL,
ID_COMPANY VARCHAR2(20 BYTE)
)

Table created.

CREATE SEQUENCE test_sequence
START WITH 1
INCREMENT BY 1;

Sequence created.

CREATE OR REPLACE TRIGGER test_trigger
BEFORE INSERT
ON test_table
REFERENCING NEW AS NEW
FOR EACH ROW
BEGIN
SELECT test_sequence.nextval INTO :NEW.ID FROM dual;
END;
/

Trigger created.

Now, test adding sample data

SQL> INSERT INTO test (ID_COMPANY) VALUES ('ABC123');

1 row created.

ps : Oracle is sucks. MySQL is sexy!

Port Scanner

File list

1) Scar.jar
2) scan.sh (runner for linux)
3) scan.bat (runner for windows)
4) README (RTFM)

ps : This is very simple port scanner, does not support proxy and no error handler, but still can be used. I just spend less than an hour for this, if there is any bug, please let me know.

Ping Specific port in JAVA

This class is for testing the connectivity to a database. Very useful to avoid data missing during db server is down. Data can be save in file or store in another db server temporarily.

package com.blogspot.lxnx;

import java.io.*;
import java.net.*;


public class Pinger {
  public static void main(String args[]) {
    try {
      InetAddress addr = InetAddress.getByName("localhost"); 
      int port = 3306; 
      SocketAddress sockaddr = new InetSocketAddress(addr, port); 
      
      // Create an unbound socket 
      Socket sock = new Socket(); 
      // This method will block no more than timeoutMs. 
      // If the timeout occurs, SocketTimeoutException is thrown. 
      int timeoutMs = 2000; // 2 seconds 
      sock.connect(sockaddr, timeoutMs); 
      System.out.println("Alive!");
    } catch (UnknownHostException e) {
      System.err.println("Unable to lookup");
    } catch (SocketTimeoutException e) {
      System.err.println("Connection timeout");
    } catch (IOException e) { 
      System.err.println("Unable to reach");
    } 
  
   }
}

I just read, a post about this FizzBuzz thing, here then go to the original post. Then, i write the code in Java just for poc.

Here is my code

public class FizzBuzz {
  public static void main(String[] args) {
    for(int i = 1; i < 101; i++) {
      if (i % 3== 0 || i % 5 == 0) {
        if (i % 3 == 0)
        System.out.print("Fizz");
        if (i % 5 == 0)
        System.out.print("Buzz");
      }
      else
      System.out.print(i);
      System.out.println("");

Where 'NEW_PASSWORD' will be your new ROOT password
7. After you are finished close the first command prompt and type "exit;" in the second command prompt windows to disconnect successfully. You can now start the MySQL service.
