Append Multiple Rows In A SQL Database Table With Primary Key?
Aug 9, 2011
I am trying to append multiple rows in a SQL Server.I have connected to the MS SQL Server and with a DataAdapter, I have downloaded the Table into a DataTable and displayed it in DataGridView.I now want to programatically enter multiple rows into the DataTable and later to update the SQL Table.
I am trying to build an application to do this generically.The problem I have is that the Table and DataTable has an 'ID' Field. In the SQL DB, i is an Auto-incrementing field.When the code loops through creating new rows and entering field values, how do I handle the ID Field that is the Primary Key?

I am attempting to fill a form with multiple rows from an access table based off of a parameterized query. My query works fine but I don't want to return one row at a time, I want to return all rows that match my query in multiple text boxes. I know that I can use a datagrid view to accomplish this, but I would prefer the look of a textboxes on a form. I have read through many books and searched the internet forums but think I may just not know what to search for as nothing has worked yet. Can anyone point me in the right direction. So far I have tried setting the text box value to the row().item(), creating a different dataset for each row, and even setting variables for the results of the query to then be passed to the text boxes. Since none of this work, I don't really have any starting code to post. If I could just get a starting point I could work from there, so don't feel the need to code anything for me, just set me in the right direction.

I have a vb.net web application and when a particular function runs , i get data timeouts in the rest of the application..(ie..row not found errors or column does not belong to table but it does) The function is adding multiple rows in multiple tables in the database and is running in a for loop. It seems to be all SQL related but I am not seeing anything in the error logs in SQL or in the application Right now I am assuming it is memory related where to start note..the for loop will be replaced with a bulk insert but right now I jest need to resolve the issue of the timeouts

Have a method who gets data from one table, put the data into variables before it it returned into the same table with changed ID etc. My problem is that it adds the first row without any problems, but when it is supposed to add row number 2 the error says tha the row allready exists in the table. and I can not understand why. I have put in a couple of messageboxes to se that the ID is changing and that the ordreID is correct and changing as they should and they do, but stll I get that errormessage.
My code looks like this:
Public Sub Ordreupdate()
Dim dtbl As New DataTable
Dim dt As New DataTable
dtbl = Kalkyle1DataSet.Tables("Ordre")
dt = dtbl.Clone
[CODE]...
Annyone who can see why I get that error?

I have the following function that returns only the 1st row of data and puts it in a nice table. My knowledge in this area is limited in that I don't know how to create the table to return multiple rows. Can you show me how to change this to return all rows, no matter how many there are? my sql select statement may return 0 rows or many rows.

I have a Windows application form. Directly on the form I have a lable ("Customer Names"), a ComboBox (pulling actually names from a database) , and a Buton to add a customer to the database if i choose. Additionally I have ControlTab(3 tabs) that has "fields" and its own Buttons to insert data into a different table. The first 2 tabs have textBoxes, which are completely functional, but the 3rd tab has a "DataGridView"

Any method that can effectively get the total number of rows that is StartRows to EndRows in a database table and then get the corresponding data from that row as currently I am having difficulty in retrieving out the correct row of data to the column that I am comparing. It will always get the first row of data regardless of which row I put in the handphone number which I'm comparing to. The codes below is the one which I am currently using now to detect the maxrows in the database and also to retrieve the corresponding information.
MaxRows = ds2.Tables("CustDetail").Rows.Count
MaxRows = MaxRows - 1
Dim numbers() As Integer
Dim EndAt As Integer
inc = 0
[Code] .....
I used a msgbox(n) to see the number of rows in the database but it displays only one where I have two rows in my database. The for loop is the one which will detect the number of maxrows and also retrieve out the corresponding details. But apparently this is not the appropriate way.

I am trying to select multiples rows from a database table and insert the text into several "label" controls. For example, if the database search returns 5 results. then insert the first row's text into label 1, the second row's text into label 2, and so on. The number of rows will be variable. I was thinking of a while statement. I am having a problem understanding how to even seperate multiple rows from a query in VB. Would using an array for the query results be the right way to go? row one would be row(0), row two's text would be row(1), etc.

I have an access table that I'm loading into a dataset, then I'm binding the dataset to a bindingsource. The bindingsource is the datasource for a datagridview. I can use a command builder to update the entire table, but I need to update all the rows (or changed rows) in specific columns. I have a column called "dPrint" which is Boolean. I'm not sure how to use the bindingsource as my datasource in an Update Command. I've tried this:

I am looking for a howto or someone expert in ADO.NET who can explain me how to properly solve the following scenario:I have two datatables in a dataset:
ParentTable (ParentID, Name) for user data ChildTable (ParentID, ActivityID, ...) for schedule data
Tables are linked together at the database level by ParentID which is an Identity column in ParentTable.
Both tables are data bound to a separate DataGridView on the GUI. There supposed to be a "1 parent/N children" relationship between the tables, meaning if I create a new entry in the ParentTable (a new user) I get a clean DataGrid in the child grid to type schedule data for the user. So I setup two DataAdapters for each table to fill their result into a DataSet. I also set up a DataRelation object and assign it to the DataSet to link the two tables by their ParentID columns. Also when I add a row into the ChildTable via DataGrid I use SetParentRow to set the parent row.

Since ADO.Net uses a 'disconnected' model where the data available to a single program is just a copy of what is in the database, what is the normal way to handle multiple programs needing to update the same table in a database? The problem I see is that a program can't update unless his copy of the data is the most up-to-date. Are we supposed to read before updating and hope that the update occurs before someone else changes the data?
