Thank You ALL for making SQL Data Camp @ Chennai a GRAND SUCCESS

Organizing an event is a tough job and making it a great success is toughest job. I hope, Chennai SQL Server User Group did what it makes to say SQL data camp a GRAND SUCCESS,
At this moment being the chairperson of the organizing committee, I would like to thank people who were involved in bringing success to the first ever day long SQL Server event in India.

Speakers:
I would like to thank all the speakers for accepting our invitation to deliver a session.

Pinal, travelling from Malaysia to Hyderabad and to Chennai only to make for this event and delivered two excellent sessions on indexing.

Madhu, Sudhir Mahendru and Basker Krishnamoorthy(members of Data Architecture Center of Expertise (DACoE) of Cognizant Technology Solutions) - This team was impressive in making clear to audience why DATA DESIGNING is so important to any application development lifecycle.

Venkatesan Prabhu, I have to make a special mention about him. He made great changes to his vacation calendar just to make for this event and was pleasant to have him travelling from Australia at the right time.

Raymond, from Doubletake software presented one of the most exciting sessions on high availability with Doubletake. I have never seen an UG giving one full session to a sponsor and we are proud of making our sponsor a part of our team.

Sponsors:
If speakers were driving the event throughout the day, it was our sponsors you were with us from the day we planned till this last moment bringing energy and enthusiasm among us. The following are the persons who drove us through success.

Blythe Morrow, Sujatha Metha, Sanj Gaddam of PASS.
Doubletake Software
Redgate software

Jacob Sebastian of BeyondRelational.com

My User Group Colleagues - Vidhyasagar and Deepak:
These both, I have no words to thank them; I am New York and was instructing them to do what needs to be done. And these guys have accomplished more than what I asked them. They have always been part of my community journey and this one is next stepping stone for us. We together have set a new milestone of conducting an event for SQL Server and we will make sure we will better this one in future events.

User Group Members:
This group has been one of the most active SQL server user groups around India and the members have been most energetic lot. They are the one who bring us enthusiasm and energy for us to take steps forward.

Personally, I was so proud to hear from Pinal, Vidhyasagar and Deepak that there so many attendees wanting to meet and chat with me. I apologize for not turning to be there. But I will make sure that I will meet everyone when I am in India for vacation.

Nagesh, Selva and Senthil:
These three need a special mention here. They have no association with either this User Group or SQL Server but were kindhearted enough to help us from designing the Logos, website, arranging things, coordinating with vendors, loaning their personal car for shuttle and what not. Thank You guys. Without you we would have had tough time managing things around us.

I would once again take this opportunity to Thank everyone for making this event a GRAND SUCCESS.

If I would have missed someone, please apologize me.

Thank you All.

The Unhealthy Argument

This post of mine is 100 percent a personal opinion and was written not to hurt anyone.

Off late, I have been hearing or knowing incidents which have involved 2 or more persons going into an argument on deciding which technology is the best is it WINDOWS or UNIX, ORACLE or SQL SERVER, .Net or JAVA, IE or Chrome, etc. There are few incidents that came to my notice which I would like to share with you all.

1. This was between friends of mine who worked in my previous company; they both work in the same team providing support to one of their clients. One is an ORACLE DBA and other is SQL Server DBA. They have argued hardly to decide which Database systems is the best and have ended up criticizing Larry Ellison and Bill Gates.

2. The next is between the web browsers, I have read a numerous articles in the blogs and other websites saying IE is the best or Chrome is the best or Firefox is the best, etc. The same has happened between my known persons where they have ended using abusive languages. I am sorry to say this, but when people lose temper that is the end result.

3. Again, between my old colleagues, about WINDOWS or UNIX, each of them have had strong points to prove that they work on the latest technology of the server side Operating systems but failed to convince others. Thank God, NO blows or words were exchanged in the incident.

Now, let me come to say this, each technology or application is designed for a purpose and has its own pros and cons with it. Thanks to my patience in the recent past that I have not had such an Unhealthy Argument like this. In my opinion, a Database or an Operating system is chosen with the needs of the application or the system to be designed. It comes as a decision on that has to be compatible with the end application to be designed. The architect who decides on what needs to be used is not a biased person, he/she knows that he has to be committed to his company's core business values and chooses one deciding on it.

So, people going forth I request each of you not to have a discussion or argument to decide which the best is. We all work on the latest technologies of what we have now and should be proud that most of us are redefining technology that has got us in the past.

Again, this is a personal opinion and was written not to hurt anyone. Thanks for taking time to read this blog. Your comments on the same are welcome.

Back to Blogging

It has been almost 40 days since my last blog. I am back to work and people can expect more SQL Server related stuff on this blog again. If you need any specific interests, Please do send me a note so that the same can be put as an article.

Many thanks for reading.

Awarded MVP Again

I am Happy to say that I have been Awarded MVP for this year too. Adding the TAG MVP to my name had always distinguished me from other technologists near me. It has been a pleasant experience and happy to be on those same lines again for another year. And it's Thanking time again for those who have made a difference in my life and for those who have been with me during my tough days this year.

Krishna Gopalan - KG, I wish to be near you to share the joy this moment. I can still hear you saying "Sugesh, I know you are the right person to do this job", whenever I heard that gave me confidence to enrich my skills as a DBA helping me to achieve near expertise.

Stephen Seth, Vidhya Sagar and Deepak - It is with these guys that I grew up enriching my SQL Server skills. Without them, I would still be a DBA not a MVP.

I would like to thank my friends Dalavai Shanmugha Sundaram, Mr&Mrs. Stephen Seth, Mr&Mrs. Arun Kamaraj, Chakravarthi Elangovan and Poornima rangaswamy for being with me during this tough days of personal and professional career.

A special mention of thanks to Rangaswamy and Rani Thilagam Rangaswamy for shouldering my responsibilities in India when I stay in USA.

And my parents and sister, I have no words to thank them. Without thier support and encouragement I would not have got this again.

Change Data Capture

This article introduces to a new feature in SQL Server 2008, Change Data Capture. Change Data Capture records insert, update and delete activity in your table and the details of these changes are available in a format that can be easily consumed. The database must be enabled to Capture Changes to it. A member of sysadmin fixed role can enable the change. Once that is done, members of db_owner can enable tables for which change needs to be monitored. When the first table in the database is enabled, a capture process gathers changed data from the transaction log and inserts the change information in the associated change table. Additional metadata about each transaction is inserted in a metadata table that allows the captured changes to be placed on a conventional timeline.

Step to Enable and Configure Change Data Capture:
1. Create a database SQL Server 2008
create database CDC_TEST
go
2. Enable CDC in the database created.
USE SQL2008CDC
GO
EXEC sp_cdc_enable_db
GO
You can verify if CDC is enabled using the query below for the database.
select [name] as DBName,is_cdc_enabled from sys.databases where db_name(database_id)=DB_NAME()
3. You will be a new schema CDC and few system tables created under the database. Change Data Capture requires exclusive use of cdc user and schema.
4. Create a table to enable CDC
USE CDC_TEST
GO
CREATE TABLE dbo.CDC_TEST(
ID int Primary Key NOT NULL,
Name nvarchar(100) NOT NULL,
Email nvarchar(100) NOT NULL)
5. SQL Server agent must be started for CDC.
6. Enable CD for the table where you need to capture the change.
EXEC sp_cdc_enable_table 'dbo', 'cdc_test',
@role_name = NULL, @supports_net_changes =1
You can verify if CDC is enabled using the query below for the table.
use SQL2008CDC
go
select [name], is_tracked_by_cdc from sys.tables
7. Once CDC is enabled for a table, you will find a _CT table created by itself.
8. Now we will verify how CDC works by running a insert into the table CDC_TEST.
use SQL2008CDC
go
INSERT INTO dbo.cdc_test
values (1, N'sugeshkumar', N'sugeshkr@gmail.com')
9. Now update the row that we have inserted in the previous step.
use SQL2008CDC
go
update dbo.cdc_test set name='sugesh' where id = 1
10. The before image and after image of the row can be found on the table that was created with the name _CT.
The column _$operation has the value for the DML operation done, 1 is for delete, 2 for insert, 3 for before image, 4 for after image

You have seen how to enable and configure CDC for a database and table. The list below gives you all available Stored Procedures, DMVs, Functions and table list that is used by Change Data Capture.

Common SQL Server Security Issues and Solutions

This article is from Paul S Randal on securing SQL Server. This is a nice article on how to secure SQL Server.

Show/Hide divs and swap images with SkinID using Javascript

The following example shows 2 ways of using javascript to show/hide divs (or any elements) on the click event of an image and also to swap the image that uses a skin id. Since skins are applied on the server side, you cannot change SkinID on client side using javascript. Though this is a crude way of doing it, it worked for developing my website since this functionality is used on only one page. I am sure there are more better and easier ways to do it, but these examples can be used in a simple website that uses asp.net or HTML.

Example 1: To Show only one div at a time.

ASP.Net Code

<div id="divContent">

<h2><a href="#" id="lnk1" onclick="return toggle('div1')">What is Test?</a></h2>
<div id="div1" style="display:none">

   Test Test Test Test Test</p>
   <p>Test Test Test Test Test Test Test Test Test Test Test Test Test
   Test Test Test Test Test Test Test Test Test Test Test Test Test Test Test
   Test Test Test Test Test Test Test Test Test Test Test Test Test Test Test
   Test Test Test Test Test Test Test Test Test Test Test Test Test Test Test
   Test Test Test Test Test Test Test Test Test Test Test Test Test Test</p>
</div>

   var divUL = document.getElementById('dvfaq');
 var divs = divUL.getElementsByTagName('DIV');
 for(var i = 0; i < divs.length; i++)
   {
     divs[i].style.display = 'none';
     if(divToShow.style.display == 'none')
     {
      divToShow.style.display = 'block';
     }
   }
   return false;
