SQL Server- Case Sensitive Search in SQL Server

Case Sensitive Search in SQL Server
Today I was working on text search functionality in my application. 
It was not a very big deal until I had not a requirement for Case Sensitive search functionality.
 I Googled it and find number of search results with same solution.
 So here I am just adding one more search result for Google.

In previous posts, I was explained about how to
I explained  and some other articles related to Now 
In this Article will see how to search In SQL Server- Case Sensitive Search .


In  SQL Server ,  Installation by default are case insensitive .This means that SQL Server ignores the 
case of the characters and treats the string 'Dot Net World' equal to the string 'dot net world'.
Let's see a practical example. Suppose we have a table say "BlogName" with following records-
Table
Now If we execute the following query-
SELECT  Name
FROM  BlogName
WHERE  (Name LIKE '%net%')
It will return all record because all rows contains same data and search is case insensitive by default.
Now question is how to make it case sensitive? Answer is very simple. You have to change the 
 collation of above query as shown below-
SELECT     Name
FROM         BlogName
WHERE     (Name LIKE '%net%' COLLATE Latin1_General_CS_AS)
Now, execute the above modified query and see the result-
Case sensitive search query result
This is the result which we want.By above method, we change column collation 
 for temporary use. but we can change it's collate permanently. by using following Query-
ALTER TABLE Table1
ALTER COLUMN Column1 VARCHAR(20)
COLLATE Latin1_General_CS_AS
To know the collation of the column for any table run following Stored Procedure-
EXEC sp_help BlogName
Here is the result of above query-

I hope this will be helpful for you. I would like to have any feedback from you. 
Your valuable feedback, question, or comments about this article are always welcome.

How to hide url parameters in asp.net

There are different ways to Hide the URL in asp.net , you can choose any one from bellow options . Previously I was Explained about the  Difference between Convert.tostring and .tostring() method Example  ,   Reasons to use Twitter Bootstrap , How to Register AJAX toolkit in web.config file in asp.net a) Using Post Method b) Using Of Session . c) URL Encoding & decoding process . d) Using Server.Transfer() instead of Response.Redirect() method (1)Use a form and POST the information. This might require additional code in source pages, but should not require logic changes in the target pages (merely change Request.QueryString to Request.Form). While POST is not impossible to muck with, it's certainly less appealing than playing with QueryString parameters. (2)Use session variables to carry information from page to page. This is likely a more substantial effort compared to (1), because you will need to take session variable checking into account...

It's damn simple and easy. Just pass document path as attachment as parameter and we are done. Google Docs Viewer gives us ability to embed PDF, DOC/DOCX, PPT, TIFF:...
