Get @@IDENTITY of new inserted record,

I am using VS.net (2003) SQLcommand TEXT. with input params.
SQL server 2000

Can anyone tell me how to get the Identity value (field value, Idenity col) when you do an insert? I want to get the Identity value, then redirect the user to another page and use this identity value so they can update more (other) fields that are on that page.

My code so far that works... but Where do I put @.@.IDENTITY ?
How do I call or assign the @.@.IDENTITY value to a value in my aspx.vb code page?

Question: how do I get the Identity value from the ID column.
Question: How do I assign that value to some variable in code, say, assign it to (Session("App_ID")) = IdentityValueOrSomething?Help...
-------
INSERT INTO App
(AppName, Acronym, Description,bla bla bla bla......)
VALUES (@.AppName, @.Acronym, @.Description, bla bla bla bla......)

----------

Private Sub btnAddApp_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddApp.Click
With cmdAddApp
'.Parameters("@.app_id").Value = Session("App_ID")
.Parameters("@.AppName").Value = txtAppName.Text
.Parameters( bla bla bla..........
.Parameters( bla bla bla..........
.Parameters( bla bla bla..........

End With
Try
cnAppKBdata.Open()
cmdAddApp.ExecuteNonQuery()
cnAppKBdata.Close()
''Session("App_ID") = whatever the @.@.IDENTITY is...'''??
Response.Redirect("AppUpdate.asp")
Catch ex As Exception

End Try
End Sub

Anyone have the lines of code that does this?

Any advise or examples :) thanks you.Well you have a few options here. to name a couple, place it in an output parameter or a return value. I think the better choice is an output param as return is typically reserved for returning custom errors and messages.

Also have a look at scope_identity vs @.@.identity

Get @@Identity from a remote SQL Server

I am using SQL 2000 server. I have a SP that insert a
record to a remote server table with Identity column as
the ID. After the insert, I try to use @.@.Identity to get
the newly inserted ID back. I got NULL. However, it works
when I run the same SP against a DB on the same server.
How can I get the ID back from a remote server?
Thank you for any inputTom
It works.Thank you a lot.

It works but sometimes I get dead lock. Because this
exec statement starts a new process on the remote server.
After this I have other update/delete might agaist the
same remote database objects which are within the same
procedure ,therefore the main thread. Looks like the exec
started process does not cleanup itself after it finishes
it's job. Is there a way to kill itself after it is done?

Generic Database Design

Hello,

Can someone please guide me to online resources or books on how to design generic database? I mean, I can have a "Record" that can have a set of fixed fields like: ID, Title, CreatedOn, etc ... and I can add as many properties I want to that record in a vertical way.

Then based on the generic tables present, I can fit in the same table, a Record for Customer, a Record for House, a Record for Order. All share the same set of Fields, but each has its own set of proeprties.

This way, I design my database once, and customize it to fit any type of applications I need.

Is there something like that or just dreaming?

thanks

One way you can go about doing this is build a tool to generate the necessary sql to create the database tables. You can even have it create the stored procedures and code behind to access it. Im not sure if there are tools out there for this, I just wrote my own.|||

Thanks for the reply!

Maybe I was misunderstood. I am asking about having a database design that fits all kinds of applications. I mean design the database once and use it for all my applications. I talked about notion of Record that can hold any object!!

Any more ideas?

Thanks

|||

Perhaps you are talking about the model database in SQL Server. The model database in SQL Server is a template database which can be generalized so that every database created afterwards includes some pre-generated objects. Below are some of the links that you may find useful.

http://articles.techrepublic.com.com/5100-9592_11-6126240.html

http://www.sswug.org/see/30280

Explain your problem in details so that we can help you better.

Hope this will help.

|||

Hello,

Thanks for the reply.

My point is that I want to design a database schema that can fit any application. I mentioned about Record table. This table can hold information about any object regardless of its nature. All objects share a set of predefined fields. I can also assign to each object a number of properties that might be defined somewhere else also in another data table.

My idea is to have a single Database Design that I can use to make it fit for any application. for instance, if I have an application to handle customers and orders, I would define a Record for each object.

Record for Customer

Record for Order

In the database I don't need to do anything, but define two record instances. one for Customer and one for Order. Add any proeprties to each. On the other side, I would develop an API that deals with Records only, regardless if this record is Customer or Order. Each record would have a set of predefined fields and a collection of properties.

Am I making any sense?

Thanks

|||

Its possible I still dont understand you, but how many columns (properties) could every record possible share? Like theres an ID but other than that you are not going to need the address and phone number for Order, but you will for Customer. Im not sure what you hope to accomplish by doing this. Do you want to be able to programmitcally add new columns to a table?

Or are you talking about assuming that you will need an Order table and a Customer table in every project you work on, and you want to create almost a template that you can modify to fit the needs of some specific project?

|||

Hello,

What I am thinking of is to have a notion of Record. A customer is stored in one record and an order is stored in one record, a student is stored in one record, etc ... This includes only basic fields.

Also, I want another table call it Property, that holds additional proeprties of each record. By using properties I can customize my database to configure any new website's objects with the propeties required. So you can think of having one framework for the database design that can fit any project.

Does it make any sense?

Thanks

Generating unique id strings

Hi
I want to generate a unique record number in the following format
Company initials/year/Counter/RecordType (e.g. SDS/04/00123/WB)

Could someone recommend how I go about generating this number?

Should I create a separate table with columns for each section of the number and concantenate the columns in ID field of the actual table?

... or should I just create a stored procedure to generate the number each time?

... or should I do something completely different?

Regards
John :confused:First, I'd recommend against doing this unless this code is required by the business process, i.e. recognized by the system users. Such codes are of little or no value to the application.

If all four of these values already exist in the table, then you could add a calculated column to your table that concatenates them to form the ID. These types of keys are often called "Superkeys", but with the availability of composite keys they are of little use these days and are often difficult to maintain.|||Thanks blindman, I'll take your advise and k.i.s.|||you could create a formula to concatenate the other fields and use it as the default value of a new field in the same row

I don't think I explained this very well

er

read about using formulas as default values in BOL

GW|||As a default value it would not update automatically if any of it's components change. That's the advantage of a calculated field.|||Apologies

U right of course blindman

I was'nt thinking

Generating RSS Feed from Sql Server 2005

Hi every one

I want to generate a RSS Feed from SQL Server 2005.

The scenario is that when a record is entered in the database, the database fire a trigger which generate rss feed for the new record entered in the data base

Thanx in advance

Take care

Bye

I don't quite understand why you want to use trigger to generate the RSS. You can use SQL query to generate RSS like formatted data and show it to the end user. So every time the link on which you are showing the records gets refreshed, the sql query/procedure will get executed, and the RSS format XML data will be generated. All, you'll have to do is to through the result of the query/procedure as response.

For example, visit below link. It is actually a .aspx page where the coder has done exactly what I'm talking about.

http://www.codeproject.com/webservices/articlerss.aspx?cat=3

Hope this will help.

|||

Would your best bet not be to write a page in ASP.net that generates the RSS by pulling the data from the SQL server whenever the page is called? This could then act as your trigger.

|||

Thanx for ur response

|||

Hi

Thanx 4 ur response

I think i did not convey my message rightly.

I have to generate the xml file when the record is updated in the database using trigger. i don't want to query the database directly from the application.

Waiting 4 ur response

Take Care

Bye

|||

Well, I'm still not convinced why you want to go the XML generation way. If you setup your RSS according to my previous post, you are at least worry whether new record is inserted or any record is updated.

Still, if you want to go for the trigger and xml generation way, then I think you'll have to dig down XML generation functions of SQL. Moreover, as you are also going to do IO operations in you SQL trigger, the path of the file and access permissions and so many other things should be taken care of. One way you can use is the CLR Integration. See if below link is useful:

Generating and directing new rows in PostExecute.

I want to construct a dataset based on all rows passed in from a source and, upon running through all of them, push each dataset record to an output.

Unfortunately, upon calling the AddRow method, I get an "object reference not set to an instance of an object" error. Am I not allowed to create new rows in PostExecute?

Bill,

Can you post your code, indicate which line the error occurs on, and tell us how you have configured the outputs of the component.

dsMaterialBuffer, which is the row buffer I'm using, evaluates to "Nothing" and that is where my object reference errors are coming from.

Generating a personalised report for every vendor and mailing out the same

I have the following reporting scenario.
I have a table which contains a list of customers/vendors and each
record in this table as the customer/vendor number, name and email
address of the vendor and also the record as the value of the business
done by the vendor/customer for this month, year to date, last
year,etc our business wants reporting services to generate a report
for each customer/vendor from this table and email the resulting .pdf
report to the email address on this record.
Please clarify how I can implement this solution can reporting
services do this.
Thanks
KarenPlease look up data-driven query in Books Online. You will need to create a
subscriptions table with a column for each piece of data that is different
among all the report subscribers'; e-mail, vendor number, etc.

Generate ABCs as Rownumber

Hi,
I'm using a list to generate a report. Each record on the list will
have a counter. This counter needs to be in ABCs instead of 123.
The report should look something like this.
A. First Record
some data about first record
more data about first record
B. Second Record
some data about 2nd record
more data about 2nd record..
Thanks,try doing a char(RowNumber()+64)
(otherwise you are going to have to write something custom that pulls in the
library)

generate a random int to add to a record

I need to generate a random whole number between 0 and 999 to add to
add to every record in a table. The number needs to be different for
each record in the table.

How would I do this all within TSQL?the procedure of mystery man produces random numbers but they can
appear more than once which should not happen. So it would be
necessary to create a new number, check if it exists, if not use it,
else create a new random number, ... can become a timeconsuming
problem if you try this with numbers between 1 and 999 and you have
more than 999 records in your database :-))
If you only need it to do a random read, try this:

select * from myTable order by newid()

this will show you the records every time in another order.

Helmut
