Performance of CTE(Common table expression) Vs Hash(#)Tables.

Let say we have one report and in which we want data from around 20 tables.

so i just created some 4 to 5 cte(Common table expression) for every 4 to 5 tables.

and then join cte's and get the data.but when i execute that stored procedure it will take around 10 Minutes.

i am really strange about this.

Now what i do just replace all cte(Common table expression) with Hash(#)table.

and it's executed with only around 15 seconds.

So i suggest when cte 1 or 2 then ok but 4 to 5 then you can use #tables.

This is work for me.Let's you guys try it.if you use cte and it will take too much time to execute.

Bind WebGrid in Asp.net MVC

I just learn how to bind grid in MVC. I hope you guys just know basic about MVC.
First of all You guys just have to install one package.for that got to Tools->Library Package Manager
and run command in output window
Command:- Install-Package RazorGenerator.Templating

1.) Below is controller code.

in above code i just create simple List of my model.you can also get that list from database also.

2.) Below is model code.

in above code simple properties are created.

3.) Below is view code.

Here is your view code. here one thing is that you have to take care is that is first line.i tried with @model MvcApplication1.Models.NiksModel but it means it accept model from controller.but here we are passing list from controller so you just have defined as list of your model.
