DataSource Controls :: Inserting A New Records Into SQL DB By More Than One User Simultaneously
Jul 12, 2010
I'm having a problem when two or more users simultaneous work on a webpage and provides info to create a new record in my database. the issue is that for some reason, their entries get mixed up and the wrong data gets commited to the database, how can i fix this. All the webpages i browsed for help provide optimistic concurrecny on updaing/deleting existing records, not creating new ones.
I also turned off SessionViewState, but I don't think it helps.
I'm not using a ObjectSource Control, i'm creating new instances of the BLL Classes in my code as I need. Should I null the objects after I use them? They are only created in the scope of a method, so it should essentially dispose of the object when the method completes.

What is the best method in T-SQL 2008 for extending a table's records with the criteria of 'repeating' all fields but the Primary KEY e.g. Consecutive Date for the previous n Records.
So you have for example 7 records (Easy...2 Fields. Date and nvarchar) with th Date runing from Jan-01 to Jan-07
We want to extend the table by 21 records...so
Record 1,8,15,22 will look identical apart from the DateField.
Record 2,9,16,23 will look identical apart from the DateField. etc...etc..
I have tried a number of methods ...all coming up short....

I want to insert a large amount( approx 7000 records) of data into a table, My scenarios is that i need to check whether the record already exists then it will not insert it. Currently i am using a stored procedure for this which gets called for each record.
IF EXISTS(SELECT 'True' FROM MYTABLE WHERE ID = @ID)
BEGIN
--This means it exists, return it to ASP and tell us
SELECT 'This record already exists!'
END
ELSE
BEGIN
--This means the record isn't in there already, let's go ahead and add it
SELECT 'Record Added'
IF EXISTS(SELECT 'True' FROM [Aadil].[dbo].[SharePointSitesData] WHERE ID <> @ID)

I've got a sp as below:
The functionality I want to achieve is that when isHomePageFeatured is checked then this record is set to 1 for that column and for all the other records in the table it is set to 0.
This is fine for update as I can use the property Id to compare against, but for the newly inserted record it doesn't yet have a propertyId so I wondered if using newID() to affect all other records would have the same affect.

In general, If multiple users thru an application try to update the same tables in database simultaneously, then by default on what basis the priority will be given.Like if we don't have any extra logic for the locking implemented.

I have a listview that I automatically generated from a database table, enabling editing and inserting on the listview and the EntityDataSource that runs it.
I started customizing the listview templates so that I didn't have to see some of the fields (they're unnecessary from the standpoint of the form), and have alternately tried removing or hiding the unwanted fields. This pretty much patently results in me not being able to insert new records, although updating seems to work just fine. There are no error messages.
I then tried using InsertParameters in the datasource, but that didn't really help either.
In the codebehind I have an onInserting handler that should fill in some of the hidden/removed fields before the record goes to the database.
I've tried pretty much everything I can think of, and even my colleagues are kind of stumped. Why can't I insert records into this table/listview?

Here's the next instalment of my asp.net data access nightmare!
I've got a listview on my page, and when I run the page it correctly displays the data that it should. However, when I add data into the empty new record and hit the 'Insert' button the page posts back but the record isn't inserted. Annoyingly, I don't get any error!
The listview's datasource has an INSERT command and insert parameters specified. The button seems to be triggering the listview's insert method because the ItemInserting event fires.
With no error message to go on I'm struggling to figure out what the problem is. I have a feeling it's something to do with the makeup of the page. The listview in question is nested within an Accordion control and the listview's data source isn't set until runtime, when it's done in the ItemDataBound event of the Accordion control. As I say, though, it does RETRIEVE data correctly, it's just the inserting that's a problem.
I created a new, blank page with just this listview on it using the same code but not nesting it within any other control and hardcoding the datasource instead of setting it at runtime and that works perfectly, so I'm confident that my INSERT command, insert parameters and so forth are correct.
I've tried to get my listview to break, deliberately leaving out insert parameters and so forth just so it'll give me an error message but it never does! It's as if the insert isn't taking place at all, except that because the ItemInserting even takes place I'm assuming that it is.

I've looked all over for this problem but can't find anything that works. I have a details view bound to a database that when a user enters their details and clicks insert it will store the data and then send them to another page. I have tried response.redirect but that does nothing. I am using c# btw.

lblMsg.Text = "Records Existed"
End If
but there are error message. "Object variable or With block variable not set."

Using checkboxes, can the row of record(s) be inserted into a database? I am populating a Gridview. Done. A checkbox field has been added, when the user selects one or more rows, a submit button (which is not working) needs to inserting those records into a table. The insert statment will work outside of the page but is not working using the scenario I jut described. Is this task as I have outlined doable?

This is the first time I have been working on databases and I am trying to insert data using an object datasource but no data is being inserted and no exception is thrown. I'm not sure where I am going to wrong. I am putting user data into session variables and inserting the session variables into the dataacess class layer and have a try and exception but nothing being thrown. Any help would be really appreciated because I don't know even where to start looking with this or how I can get the error to be thrown. Please see some of my code below to give an idea of what I am doing

Why am I getting two records inserted into the table, when I'm expecting and needing one? The VB code below is checking whether the HTTP is secure or not, and if it is then execute the SPROC. But for whatever reason, I'm getting two records inserted about 5 seconds apart. Does anyone know why and how to fix? I just need one record.

I am using Linq to SQL. I have a table with a uniqueidentifyer column.

I know the syntax to insert a single record for example where dc is a DataContext():
[Code]....
Does anyone know how if there is a way, other than looping 1000 times, to tell SQL to insert 1000 records generating different unique ids but assign the constant values to the other columns?
