DataSource Controls :: How To Update Database From A DataSet
Apr 1, 2010I'm fairly new to asp.net and I'm trying get my arms around the data entry and update. I have created a nice data entry formusing a stored procedure. It works well but for a test database, it's pretty much overkill, but worthwell in learning how. I'm going through the ADO.NET quick start tutorial and I've ran across a couple of questions that I've not be able to answer. In my website,I'm wanting to edit the database by creating a separate form that is filled with the existing database information for that particular id. My main question is how to I take the information from the dataset and get it into my form. The code below is not fillingmy form. Not sure what I should be using here:

Feb 25, 2010I select few columns from table A in dataset. Example "EMP_ID","Name","Address","Phone_Number". I want to save data in this dataset into some other table B.

Forms Data Controls :: Update One Or Two Columns In A Table Without Using Dataadapter / Dataset?
Mar 14, 20101. As per my knowledge we use dataadapters/dataset when we want to deal with the huge amount of column/data. Is there anyway that if I want to update one or two columns in a table without using dataadapter/dataset?
2. There is a way that without clicking a button we can get the data using objectdatasource, I mean to say that there is no vb.net data in the code behind then how to debug if there is not data in vb.net in code behind.

Sep 6, 2010I have a "hello world" database project. A mdf database with 1 table "users", the table has 2 columns userid & username (both varchar(50)). I added a dataset called Database1Dataset.xsd. I drag the table onto it and it creates the "users" datatable. I checked it to see if it created the insert and update commands and it has.
On my form I have 2 buttons, one for read and the other for write/save.
The read button works and I can see the test records in the database;

The second button should add a new record and save it down to the database but this does not work. Somehow the changes are not being commited and saved.

ADO.NET :: Will Dataset Object Work Across Different Database
Feb 10, 2011I recently have a problem while switching from regular sql datasource to the object datasource using the dataset object.
I have only 1 sql server so I create 2 database 1 for testing and 1 for running. After I create the dataset object I can use it fine with my test site and database. However, when I upload to it use on the production database (I actually just have to switch the sql connectionstring in web.config), I keep getting error of target of invocation throwing errors.
When I do a search for the test database in the project, I can see that in the dataset object the test database's name is automatically added to my select stored procedure name (i.e. [Test].[dbo].[My_stored_procedure] instead of just [dbo].[My_stored_procedure]). I thought this is my problem but even when I replace [Test] with my [Product] database name it still won't work.
ADO.NET :: Updating A Dataset Table To The Database?
Feb 22, 2011I have an asp.net application using visual studio express 2008. On one of my pages I created a dataset from one of my database tables. I am able to delete rows and add rows to the new dataset table. I then have a button and on the click event I use the commandbuilder to update the database table. The database table updates with new rows but the deleted rows are not carried out and I can not figure out why desite spending several hours on google to resolve this issue?
Here is some of my code:
Protected Sub Button_updateDatabase_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button_updateDatabase.Click
Try
'I have created a session variable for my data adapter
Dim commandbuilder As SqlCommandBuilder = New SqlCommandBuilder(Session("Adapter"))
Session("Adapter").UpdateCommand = commandbuilder.GetUpdateCommand
Session("Adapter").DeleteCommand = commandbuilder.GetDeleteCommand
'I created a session variable for my dataset
'This update command updates new rows to my database table but not deleted rows
Session("Adapter").Update(Session("CalendarDataset"), "Name")
Catch ex As Exception
Response.Write(ex.Message)
End Try
End Sub
DataAdaptor/Dataset When No Row Present In Database Tables
Apr 21, 2010I'm trying to use a DataSet to maintain some rows for a table, and when I've finished my changes, send all changes to the database using a SqlDataAdapter.
I find if there are no rows in the table in the database then I am getting a 'Object reference not set to an instance of an object' when I try to access the table in the Dataset.
Is there a way to work with a Dataset like this ie. I start off with an empty table and I wish to add rows, to access the structure of the table rows, build rows, then add them and do the update on the SQLDataAdapter.
Here is my code:

ADO.NET :: Insert New Records In Tables From Dataset To Database?
Aug 27, 2010I have 2 tables in SqlServer 2008.
Table1: T1id, SomeData
Table2: T2id, T1id, SomeData
I am using DataAdapter.FillSchema to create shema of tables in DataSet. I created DataRelation on columns
T1id in both tables.
Now when i try to Update Sql Database T1id in Table2 remains 0 and not the value of T1id in Table1.
I can successfully update Sql Database if i fill DataSet with records first (Using DataAdapter.Fill), but that's not what i want to do. I don't need "old" records in my dataset. I want to use dataset just to store all imputs from user until the proccess is done and then insert all those records "at the same time".

But the result is it only insert the first row of the HQDS dataset...then it will give this error :"Violation of PRIMARY KEY constraint 'PK_BRANCH'. Cannot insert duplicate key in object dbo.TS_BRANCH'.The statement has been terminated.

It doesn't give any error and also it doesn't insert anything to the database.

Mar 25, 2010I have created a DataSet which is connected to an Access Database. This DataSet is linked to a report and I would like to apply a filter to only display information relevant to the logged in user. My question is, if I wanted to add a parameter to the filter in my DataSet, what is the correct syntax when entering parameters? Whatever I try, it seems to convert automatically to a string.
