Maintenance is most difficult !!

Dear Friends,

Today one of my close friend shared a lovely video. This video inspired me to write today’s post.

Its a discourse by Gaur Gopal Prabhu. The message which I received from this short and crisp video is:

Creation needs some effort,
Destruction needs no effort,
But maintenance requires most effort !!

Hope you enjoy the discourse by Gaur Gopal Prabhu.

Anari (1959) – Sab Kuch Seekha Humne (सब कुछ सीखा हमने)

Today I am posting on my favorite song from the Movie Anari(1959).
The song is “Sab Kuch Seekha Humne”.

Singer(s): मुकेश
Music By: शंकर जयकिशन
Lyricist(s): शैलेन्द्र

Lyrics in Hindi

सब कुछ सीखा हमने ना सीखी होशियारी
सच है दुनिया वालों कि हम हैं अनाड़ी

दुनिया ने कितना समझाया
कौन है अपना कौन पराया
फिर भी दिल की चोट छुपा कर
हमने आपका दिल बहलाया
खुद ही मर मिटने की ये ज़िद है हमारी
सच है दुनिया वालों…

दिल का चमन उजड़ते देखा
प्यार का रंग उतरते देखा
हमने हर जीने वाले को
धन दौलत पे मरते देखा
दिल पे मरने वाले मरेंगे भिखारी
सच है दुनिया वालों…

असली नकली चेहरे देखे
दिल पे सौ सौ पहरे देखे
मेरे दुखते दिल से पूछो
क्या क्या ख्वाब सुनहरे देखे
टूटा जिस तारे पे नज़र थी हमारी
सच है दुनिया वालों…

Chasing the Monsoon

11th July 2014 and 12th July 2014

This was the title of “Rail Bandhu” – The on-board magazine from Indian Railways, on my maiden train journey from New Delhi to Cuttack, Odisha.

In the first half of my journey the adage “Do not judge the book by its cover” felt so true. I did not bother to open the book.

In the second half of the my journey, when the train entered Odisha state. I was awestruck to notice the two extremes of the weather which existed in India. Such is the vastness of India.

I started my journey from a place where people were praying to Lord Indra to show some mercy and my journey ended where monsoon was at its full glory. It appeared that Lord Indra (The Rain God) showed special interest in this part of the world :). There was relentless rainfall occasionally accompanied by thunderstorm and lightening. I had to pray for the rain to stop so that I can carry my luggage comfortable to my to-be home for the next two years. I was on my way to Sri Sri University, Cuttack, Odisha for admission to two years full-time MBA program in General Management.

Finally, I decided to turn the pages of the on-board magazine titled – “Chasing the Monsoon”. It showed glimpses of the natures beauty during the Monsoon in different parts of India. It also showcased the new SMS alert system introduced/proposed by the Indian Railways in Railway budget 2014. This will keep the Indian Railway passengers updated about the ticket status, arrival time and departure time of trains on/from platform.

Below are some snaps I captured on my way from Cuttack station to the University Campus.

At the end of my journey, I concluded that Lord Indra is a smart manager who always keeps himself in demand.

Best Practices for Oracle Developers: Comments

CommentsComments are text embedded within SQL statements and PL/SQL code which describes the purpose of the code. Comments improve the readability, usability and maintenance of the code. Proper comment and formatting can save lot of hours of unproductive work for developers and teams.

Oracle developers can use two types of comments – In Line and Multiline. Both Inline and Multiline comments can be used in SQL statements and PL/SQL.

In-Line comments starts with — (two hyphens) and is only limited to one line.
Multiline comments start with /* and ends with */ and spans multiple lines.

Oracle uses following comment styles for its standard scripts (scripts under – $oracle_home/rdbms/admin directory) which are shipped with oracle database.

-- Copyright (c) Oracle Corporation 1988, 1999.  All Rights Reserved.
--  NAME
--    demobld.sql
--   This script creates the SQL*Plus demonstration tables in the
--   current schema.  It should be STARTed by each user wishing to
--   access the tables.  To remove the tables use the demodrop.sql
--   script.
--       SQL> START demobld.sql

In many oracle shipped sql scripts you will see REM commands (REMARK command). This can also be used to enhance the readability and maintenance of the sql scripts. A sample snippet from the mksample.sql is shown below:

Rem $Header: 02-apr-2003.14:55:17 $
Rem mksample.sql
Rem Copyright (c) 2001, 2003, Oracle Corporation. All rights reserved. 
Rem mksample.sql - creates all 5 Sample Schemas
Rem This script rees and creates all Schemas belonging
Rem to the Oracle Database 10g Sample Schemas.
Rem If you are unsure about the prerequisites for the Sample Schemas,
Rem please use the Database Configuration Assistant DBCA to
Rem configure the Sample Schemas.
Rem - OUI instantiates this script during install and saves it
Rem as mksample.sql. The instantiated scripts matches
Rem the directory structure on your system
Rem - Tablespace EXAMPLE created with:
Rem DATAFILE '<filename>' SIZE 150M REUSE 

In my PL/SQL programs I use multi-line comment style like below:

** Purpose: Script to demonstrate the top 10 features in Oracle 12c for developers
** Date: 1st Feb 2014, Saturday
** Author: Vijay Mahawar
** Website:
** Version: 1.0

Oracle allows to store comments even for schema objects like table and views and on columns of table, views and materialized views. These comments provide useful information about the table and columns to other developers.

To insert an explanatory remark on the notes column of the EMP table, you might issue the following statement:

COMMENT ON COLUMN EMP.EMPNO IS 'Employee Number assigned to Employees';

The comments defined in this way are stored in data dictionary views.

Object comments are stored in USER_TAB_COMMENTS

Column comments are stored in USER_COL_COMMENTS

To drop this comment from the database, issue the following statement:


Please use setup scripts and demo script script for this.

Note: Few minutes spent on proper comments can save hours of efforts in code maintenance and debug.
