Dynamic SQL in SQL Server - Introduction

Dynamic SQL is nothing but SQL query that is generated programmatically.

For example, we can get records of any table using the below Stored Procedure which implements Dynamic SQL

CREATE PROC GETDETAILSBYTABLENAME(@TableName varchar(50))
AS
BEGIN
Declare @SQLQuery VarChar(5000)

SELECT @SQLQuery = 'SELECT * FROM ' + @TableName

Exec ( @SQLQuery)
END

Jesus - God Thinks of you.

I received this mail and i thought its really worth to share. JESUS VS. Satan Satan went to visit Jesus in the Garden of Eden, and Satan came all happy and boasting. (Lk 4: 1-12; Job 1: 6-12) "Yes, Lord, now I have everybody captive, (well nearly everybody down there). I set traps, I used the baits of temptation, I know well what each one of them can't resist. I nearly caught them all!" (I Pet 5: 8-9; Eph 6: 10-17) "What are you going to do with them?" Jesus asked. and He was praying to God the Father. Satan answered "Oh, I am going to have some fun with them!" I'll make them divorce after they have married so the foundation of humanity will never be able to be established "the family" (Mt 19: 4-6; Mal 2: 16 ) I will make them hate each other and abuse each other, make them fall into alcohol and drugs without control.

ASP.NET 4.0 Feature - URL Routing

Let’s see the new feature in ASP.NET 4.0 known as “URL Routing”. URL Routing is a feature which is driven by the ASP.NET URL routing engine which enables the application to route to custom urls instead of actual urls which may have some querystrings etc. In the past we have seen urls like http://localhost/NewStore/Titles.aspx can be now show as http://localhost/NewStore/AllTitles or http://localhost/NewStore/Titles.aspx?ID=2 can be now shown as http://localhost/NewStore/Products/Fiction . Doesn’t this look great? Now let’s see how do we achieve this. We would be using the “System.Web.Routing” class which products us a method “MapPageRoute” which helps to do the routing. Let us see a simple example where we would have two pages one which shows All the Titles and another which shows Title for a specific Author Id. For this example I am using the Pubs Database. We would have to first create the two new Pages “Titles.aspx” and “TitlesbyAuthor.aspx” . Now the “Titles.aspx” shows All the Tit

Tips on JQuery Intellisense in VS 2008

I was trying to get the JQuery Intellisense working in VS 2008. But I was getting the error “Error updating JScript IntelliSense: Object doesn't support this property or method @ 2139:1” . I was wondering what was the problem. Then through this blog http://patrickyong.net/2009/05/08/error-updating-jscript-intellisense-object-doesnt-support-this-property-or-method-21391/ I found that the “jquery-1.3.2-vsdoc2.js” downloaded from the site has a 2 after “vsdoc” . So the file is not recoginized. So just remove that 2 and it works Cheers!!!
