DataSource Controls :: Inserting Large Number Of Records?

Mar 10, 2010

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)

VS 2010 - Presenting Large Number Of Records To User For Selection

Jul 24, 2014

I have an ASP.net VB Web app I'm working on that has a requirement to provide a list of all our component part numbers to our engineers for selection into a custom Bill of Materials for reworking of an assembly. The list of part numbers is currently generated from a stored proc in our MRP systems/SQL database. The number of records being generated is slightly over 39K part numbers.

Although the SP only takes a few seconds to generate the data the web page is taking a couple of minutes to load, primarily because of the time to fill the control presenting the records to the engineers. I've bound the data to a combobox control to the engineer. They want to be able to type the first few characters of the part number if they know it and have the list filtered or be able to just scroll the data to find the part they are looking for.

I've read elsewhere that they may be a way to only populate a certain quantity of records rather than all 39K then filter based on the users actions. Unfortunately the discussions about doing this didn't provide any examples, references, etc.

My questions are these...

Is there a better way to handle this quantity of records than a stored proc and combobox? A

ny examples of a method to populate a certain number of records then filter based on user action?

DataSource Controls :: Inserting Repetitive Records?

Mar 30, 2010

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....

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.

DataSource Controls :: Using NewId() To Identify Current Inserting Record And Affect All Other Records In Table?

Apr 27, 2010

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.

DataSource Controls :: Update A Number Of Records Based On An Array?

Feb 2, 2010

I'm putting together a way to cull out bad emails from my table.

I have an email field, of course, and a 'fail' field (integer)

Each time I send out an email, I get a bunch of emails back that the email addresses were undeliverable, so I'd like to (manually), enter them all into an array (or whatever), and then run a stored procedure which updates the 'fail' field by 1

I'm looking for both on the SQL side (I have an sProc that does the deed one at a time - just need the logic to do it in a batch like this), and how to do it in the web page.....

Forms Data Controls :: Listview Not Inserting Records?

Feb 5, 2010

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?

Forms Data Controls :: ListView Not Inserting Records

Sep 20, 2010

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.
