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

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">
   <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>
   <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>

<h2><a href="#" id="lnk8" onclick="return toggle('div8')">What is Sample?</a></h2>
<div id="div8" style="display:none">

   Sample Sample Sample Sample Sample Sample Sample Sample Sample Sample

   Sample Sample Sample Sample Sample Sample Sample Sample Sample </p>
</div>
</div>

JavaScript Code:

function toggle(divID)
{
   var divToShow = document.getElementById(divID); 
   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;
}

Example 2: To Show multiple divs at a time and click to open and close.

ASP.Net Code

<a id="lnk0" href="#" onclick="return toggle('div0', 'lnk0')">

</div>

<a id="lnk1" href="#" onclick="return toggle('div1', 'lnk1')">

JavaScript Code:

function toggle(divID, imgID)
{
var divToShow = document.getElementById(divID);
if(divToShow.style.display == 'none')
{
  divToShow.style.display = 'block';
}
else if(divToShow.style.display == 'block')
{
  divToShow.style.display = 'none';
}

var imgToShow = document.getElementById(imgID).getElementsByTagName('img')[0];
var imgToHide = document.getElementById(imgID).getElementsByTagName('img')[1];

if(imgToShow.style.display == 'none')
{   
imgToShow.style.display = 'inline';
imgToHide.style.display = 'none';
}
else if(imgToShow.style.display == 'inline')
{   
imgToShow.style.display = 'none';   
imgToHide.style.display = 'inline';
}
return false;
}

Skin Code:

<asp:Image runat="server" SkinID="ArrowClose" ImageUrl="images/arrowClose.gif"

Migrating Access Database to SQL Server

I recently received a call from one of my friend asking me, what is the easiest way to migrate a database from ACCESS to SQL Server? I was curious on answering his question and just went for a search in internet to find it was much simple than what I expected. This article describes the steps to migrate a Access database to SQL Server.

To Migrate Access to SQL Server database, download the tool SQL Server Migration Assistant for Access

Install SQL Server Migration Assistant for Access on local computer

You need to have the access database closed while migrating to SQL Server.

Goto Start->;Programs->;Microsoft SQL Server Migration Assistant 2008 for Access->;Microsoft SQL Server Migration Assistant 2008 for Access from the computer where it's installed. You will see the welcome screen.

Click Next, Create a new project by entering the Name of the project and it's location. Click Next, You will be taken to a screen to add the Access database. Click on Add Databases button to specify the folder where your access database resides.
Click Next, Here you will have option to migrate only data and/or the queries too. Here, we are migrating both data and the queries.

Click Next, You will see the SQL Server connection Screen. Here specify the SQL Server instance where you want to move your Access database along with the destination Database name and credentials.

Click Next to Link tables. If you want to use your existing Access applications with SQL Server, you can link your original Access tables to the migrated SQL Server tables. Linking modifies your Access database so that your queries, forms, reports, and data access pages use the data in the SQL Server database instead of the data in your Access database.

Click Next to start Migration.

You will see the objects and queries to be migrated. Here If there are any errors or discrepencies will also notified.
Click Ok to complete migration.

Now, you can open your SQL Server database to see that the Access tables and Queries are migrated. The Queries will be migrated as Views and you can use them as you did in the Access tables. The migration task is simple than expected. Now the next task that you will learn from me on this is HOW TO MIGRATE ACCESS REPORTS TO SQL SERVER?
