reset primary key to number 0...

Posted By:      Posted Date: October 07, 2010    Points: 0   Category :ASP.Net

 I am working with a sql 2008 server express database in asp.net.   I have a table which I will call table 1.  Table 1 has a primary key called Order_Id  which is an int and automatically increments.  After deleting all the records from Table 1, how can I reset the primary key Order_Id to zero again?

Thanks in advance,

Surrogate vs Natural Primary Keys - Data Modeling Mistake 2 of 10

In case you're new to the series I've compiled a list of ten data modeling mistakes that I see over and over that I'm tackling one by one. I'll be speaking about these topics at the upcoming IASA conference in October, so I'm hoping to generate some discussion to at least confirm I have well founded arguments.

The last post in this series Referential Integrity was probably less controversial than this one. After all, who can argue against enforcing referential integrity? But as obvious as surrogate keys may be to some, there is a good deal of diversity of opinion as evidenced by the fact that people continue to not use them.

dynamically adding sql server columns based on number of files in fileuploader


I want to create a new table to sql database at runtime.  The column names would be "Name", "Date", "Event".  I would also like to have one more column name "Image" but the problem is that since the amount of images will vary, I want the application to count the amount of files in the Multiple fileuploader and then add a image column to the table for the respected amount of files. 

For example if i am uploading 3 files in the multiple fileuploader, the names should be "Name", "Date", "Event", "Image1", "image2", Image3"

I also would like that table name to be name dynamically from the textbox Name when the user enters the information.


I have the following code to make a new table, but I dont know how to name the fields at runtime like previously asked please help!!!

Embeb a variable number of videos


I need to provide some alternate content for my non-Flash users.

I have a directory of video files that is scanned using the DirectoryInfo() function, and I want to use the results to embed all files ending in ".mov" in QuickTime players on a web form.

How would you approach this? Right now I am using the count on the array of videos to determine how many times to repeat the embed code.  But this seems inelegant.

Is there a way to have a single QuickTime player.ascx control that gets duplicated according to the number of videos available for display?

Article commenting by line number


I'm wondering what's the best way to approach an online article system that allows users to comment by clicking on the line they are commenting about? Essentially the same way Adobe Acrobat works with comments where you can click anywhere and the text is saved for that location.

I'm assuming a mix of jQuery would be the crux of the interface. The system would need to save comments so that when another user logs in, they will also see the other comments but they can´t edit them - only add their own.

Any suggestions would be great.

Passing Primary Key to User Control to Display Record Detail


I'm building a user control to display detail information on a parent record. The user control will be displayed via an Ajax Modal Popup. The user control works and is displayed when expected. The problem that I'm having is that I'm not able to pass in the primary key for the parent. The control is displayed via the _ItemCommand event of a Repeater. In the markup for the user control, I explicity set the ContactId to 0 to avoid an error when the control loads (its still underdevelopment, eventually that I'll check if the value is valid).

I was assuming that I could change the property in the _ItemCommand event, but obviously its not working.

In the Page_Load event this code successfully sets the ContactId property of the control. The _ItemCommand event appears to set the value. However when I set a test label on the user control to the Me.ContactId, its showing '0' as if it was never passed in.

        UserControlContactDetail.ContactId = "1462"
        test.Text = UserControlContactDetail.ContactId

    Protected Sub RepeaterDirectory_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.RepeaterCommandEventArgs) Handles RepeaterDirectory.ItemCommand

Using Ref as an increasing primary key value


Hi. I need to set the Ref value as an increasing value starting with the number 2010 ... it will be a 12 digits characters.

I tried using identity but it doesn't work. Could anyone advice on how should one could insert an increment of 10 to the ref value? In case, my explaination is not clear, below is an example.

For an example:

Record 2: ref - 201000000133

Record 3: ref - 201000000143



How to show 0 as first number in column


Hi guys. I have two little problem.

I have database with one table and it has 4 rows.

1. I want to show a zero in front of all number. Actually i added but it doesn't show.

2. If i don't put any value in column is it possible to have minus for example instead of 0?




I post it like that because i can't see how to post pics directly.

P.S. The columns with numbers have checked "allow nulls".

I draw in paint so it's not so good but i think it's understandable.

10x in advance.
