I don't understand this code (listed below). this code attempts to modify the products table . It creates an update, delete and insert command. I don't understand where it gets the data values from. What I mean is that, how does it know which record to delete. there in no input box or textbox from where it can get the product ID, which would identify which record to delete.[code]...

I need some help in using a stored procedure in my case below: I have a table with a single XML column which takes in fields VoucherCode and Quantity, the data in SQL xml column looks like this:
<CampaignVoucher xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" VoucherCode="Vouch001" Quantity="2" />
The below method will call my stored procedure to check if a particular voucher exist based on my voucher code and then either add a new row or update an existing voucher in my gridview:
Protected Sub btnAdd_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnAdd.Click
Dim dbCommand As DbCommand = Nothing

I have a radgrid bound to a SqlDataSource that includes a hidden, readonly column that stores a pk. I want to pass the value bound to that column to a stored procedure for Updates but the default behavior when the column is readonly is not to pass the parameter to the sqlDataSource. My question is whether there is a way to pass that value without having to go into the code behind. Here is a snippet of my asp markup.
<telerik:RadGrid ID="rgEmployees" runat="server" AutoGenerateColumns="False"
DataSourceID="sdsEmployees" GridLines="None" AllowAutomaticUpdates="true" AllowAutomaticDeletes="true">

If I set readonly="false" on the It works fine but then the user can edit the primary key value which is not desired. I know work arounds in code behind but is there any way to do it straight in the markup?

I am a Newbie using SQL server and vb.net in VS2010. I am re-writing an existing application which is written in an old programming language. I have a table with invoice records waiting to be assigned an invoice number and invoice date. I have two ways of updating these records , the first way is the user manually selects which records/rows to be updated for a specific customer account number. This all works fine.
I am trying to write a stored proc which goes through all un-invoiced records (i.e., invoice number = blank) , it is to group records/rows by account number and assign next invoice number (which I already have astroed proc to fetch) and then when the account number changes to move onto the next batch of records for the next account.
I'm currently writing a small app that takes data provided by an SQL stored procedure and makes it available for easy export for non-tech savvy users. I'm trying to make this as generic as possible, in that you should be able to plug in just about any SP and follow my template to have an export utility. I'd like to add a way to get the column names before running the SP from the SP itself. I had assumed you could just run the SP with impossible values so nothing is returned, then get the columns from the resulting VB.NET DataTable. However, if there is no data returned, the column names aren't returned either. How can I get the column names from the SP without having to hard-code them?
View 1 RepliesI'm working on a .NET component that gets a set of data from the database, performs some business logic on that set of data, and then updates single records in the database via a stored procedure that looks something like spUpdateOrderDetailDiscountedItem.
For small sets of data, this isn't a problem, but when I had a very large set of data that required an iteration of 368 stored proc calls to update the records in the database, I realized I had a problem. A senior dev looked at my stored proc code and said it looked fine, but now I'd like to explore a better method for sending "batch" data to the database.
What options do I have for updating the database in batch? Is this possible with stored procs? What other options do I have? I won't have the option of installing a full-fledged ORM,Additional Background Info:Our current data access model was built 5 years ago and all calls to the db currently get executed via modular/static functions with names like ExecQuery and GetDataTable. I'm not certain that I'm required to stay within that model, but I'd have to provide a very good justification for going outside of our current DAL to get to the DB.
Also worth noting, I'm fairly new when it comes to CRUD operations and the database. I much prefer to play/work in the .NET side of code, but the data has to be stored somewhere, right?

Update with SQL Generating this Error: Could not find stored procedure 'False'. I'm not using a stored procedure i'm doing a simple update
Dim cmd As New SqlCommand
Dim connconnection As New SqlConnection(conn)
connconnection.Open()
[code].....
The store procedure which give me the information I need is:
USE [UCSMIS]
GO
SET ANSI_NULLS ON
[Code].....
When I try to add it to my report it gives an error, is it because of the temp table and how should I go about it?
I have a stored procedure to update a table, but needs a couple of values from another table.
the first two selects get the value from the table and then are used in the update statement.
The select statments:
Select @iStatusDropDownValueID = iDropDownValueID
From DropDownValue
Inner Join DropDownValueType On DropDownValue.iDropDownValueTypeID =
[Code].....
First, the values that are retrieved by the first two select statements are always the same. So they could be passed in by the code itself. I don't know that this will speed things up at all, just make the entire stored procedure better and easier to read.
Second, if the "Value Name" should change this store procedure will break (which is possible, but not often).
I am looking for any insight into the Best Practices for this situation.
I'm trying to write some generic code in VB.NET that determines whether or not a SQL server database table contains an identity column and, if so, to return the name of that column.I'm working in Visual Basic 2008 Express and have created a SQL database, "MyDatabase" with 1 table called "MyTable". Within that table, I've got 3 columns, "ID", "Column1" and "Column2". I know, I know... inventive names. Under column properties in the Database Explorer, I've set the "ID" column "Identity Specification" to "yes" and have set the "Is Identity" value to "yes"
View 3 RepliesI am trying to learn how to program using LINQ to SQL so I downloaded a Tutorial Paper on datacontext and other subjects but cannot get very many of the examples to build with out errors as written in the Tutorial. The code that I am trying to run is as follows.[code]...
Even though I had to make some additions to solve undeclared variables it run up to the db.SubmitChanges() statement which give me an error message declaring the following "Cannot insert Explicit value for Identity column in table orders when IDENTITY_INSERT is set to off. I used SQL Server Management studio to attach the database and ran a query to turn the IDENTITY_INSERT to on but when I detach and try to run my code against the database I keep Getting the same error. I can look at the ord variable and see that the OrdersID Var is set to nothing. I tried to give it a number 1 higher then what was in the database but it still didnt work. I have looked all over the internet and found much information using scripts and querys in SQL management studio to turn IDENTITY_INSERT on and off but none to do it from visual basic SQL to LINQ code.
I have 2 tables that are related,both have identity columns for primary keys and i am using a vb form to insert data into them,My problem is that i cannot get the child table to get the primary key of the parent table and use this as its foreign key in my database.the data is inserted fine though no foreign key constraint is made.I am wondering if a trigger will do it and if so how. All my inserting of data is done in vb.The user wont insert any keys. all these are identity columns that are auto generated. If a trigger is my way out please illustrate with an example.
View 2 RepliesI am using ADO.NET Datasets in my VB Applications. I have a typed dataset with one Parent table and many child tables. I want to generate Identity Key when I insert data into Parent Table and then update the data in all child tables with the Same key (As Foregin key).At last, I want to update the dataset in Database(SQL Server08).Well, the above thing can be possible by first inserting Parent Table in Database directly, get the Identity column and than use to for Child tables.

View 2 RepliesI have noticed the following but unable to understand why.Whenever a procedure is called in .net it takes more time than when it is called subsequently.Even if a procedure is called after some interval it takes more time than it takes if it is called quite frequently. i am not asking about sql query or sql command. any user definded function or user defined method takes much more time to finish when it is called occasionaly. but when the same procedure is called quite often it finishes a lot faster. why?
View 1 RepliesI am currently building an ASPX webpage for internal use. Basically, there are two buttons on this page and I need each one to kick off a different stored procedure on our local SQLServer based on the needed task. these stored rocedures do quite a bit of work and take 3-5 minutes to finish running. In neither case do I need any kind of gridview or other output from these stored procedures, as they are simply crunching/cleaning data that will populate some tables that the user will then use to complete their task. There are also no inputs or parameters needed.
So i'm OK at ASPX and pretty good at SQL, but have no idea on the VB code behind page. This is what I have ben able to put together based on 3 days of googling. i think i am close but can't quite get across the line.
CODE:
I'm not sure if you need to see any of my ASPX or my SQL. both work fine on their own, but i am not able to get these buttons to work.
I have a stored procedure that when I run it within my application it times out, but when I use Management Studio and pass in the same exact parameters, the stored procedure executes under a second. I had this exact same issue with the same stored procedure before, and all I did was recompile it, and it fixed the problem, but I do not want to keep having to recompile this stored procedure every few days or so. Has anyone else ran into this issue before?
Another note I would like to mention, is that I'm currently working on a test database, so I'm not inserting, deleting or updating any of the records that the Stored Procedure is using. So the database itself is not changing, but for some reason the Stored Procedure is showing degradation, and at the most we have 2 users in the database at a time.
Below is the code I use to call the Stored Procedure from my app.
cmd.CommandText = "sp__RECAP_SELECTION_GET_GRID_RECORDS_RECAP_TYPES"
cmd.Parameters.Add("@FK_KitchenID", SqlDbType.SmallInt).Value = cmbKitchenCustomer.KitchenID_SelectedPrimaryKey
[Code]....
As I mentioned, if I run the Stored Procedure within Mangement Studio, it runs with no problems. Also if I recompile the stored procedure, it runs fine within the app, but after a few days, the stored procedure starts to timeout again within the app and I need to recompile it again.
I am pretty new to VB and I am not sure why this is not working, basically I am trying to run a stored procedure from my web code. The sp runs just fine in SQL, I've tried it several times so I am sure that is not the problem. I don't want to return any results, I just want to see an "ok" statement if it runs and an error message if it doesn't. The code I am using for the lables (warnings and confirmation) is reused from earlier on the same page, the same goes for the validations (valUpload).

The first thing I need to be able to do, is get the stored proc from the database and turn it into string format.The information I need is: The return set of columns, tables used within the SP, Stored Procedures called from the SP. The only way of doing this at the moment that i can think of, is though parsing the text and looking for keyword matches.
