Types of Cursors in SQL SERVER


The types of Cursors are as mentioned below

Static
The static cursors are those where the data on retrieval is not modified and remains as before it entered the cursor since its stored in the tempdb. This is also know as read-only cursors.
Forward
The forward only cursors can move forward in the result set.
Dynamic
The dynamic cursors identify all changes to data inside of the cursor or from outside by other users. If a particular data in a row was changed after that dataset was assigned to cursor, when that rows comes up we do see the modified data.
Keyset-Driven
The keyset cursors is such that when the cursor is open it will see the modifications happened for any row outside by other user before assigned to the cursor but will not see new records added.

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. (Rom 13: 12-14) I will teach them to make weapons and bombs, so they kill each other "I am really going to have

ASP.NET 4.0 Feature - URL Routing

Image
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!!!
