TableAdapter Does Not Insert New Records?
Oct 6, 2009
I have a program that is using a dataset class, table adapter, binding source and binding navigator. The program can read, update, and delete rows from the table. However, it doesn't recognize new records and save them to the database when the table adapter's update method is called. (table was pre-populated by another process) The database table is using an identity column for the primary key. On a whim I added code to force an insert of data using the table adapter's Insert method with some hard coded values and this worked.This code was invoked after hitting new record on the binding navigator bar. Looking at the database, I notice the record I forced in skipped an identity value, which indicates to me hitting new record took the previous number. So the question I have is what would keep the tableadapter from inserting the new record when its update method is called?

Visual Studio 2008VB.NETFramework 3.5Windows Application
I have a SQL database names TestSQLVB
In it a table called tblTest2, with a three fieldstest2id , int, pk, increment by 1field1, varchar(50)field2, varchar(50)
I have a dataset named Dataset2.xsd
A tableadapter named tblTest2TableAdapter
A insert query names InsertTest2 with fields @f1, @f2 and ExecuteMode = Scalar
When I run the following code per MSDN [URL] the database does not get updated.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim testds As New DataSet2TableAdapters.tbltest2TableAdaptertestds.InsertTest2("One", "Dog")

I have a question similar to this one, but reading the (accepted) answer didn't give me much insight, so I'm hoping to state it more clearly and get a clearer response back.
I'm attempting to insert a data row into a table. I'm using TableAdapter's custom "insert nonQuery" that I wrote (it works, I tested) to accept some parameters. I'm fairly new to this business of communication with a database via .NET and what I'm doing is probably wrong by design. My questions are why is it wrong and what's the right way to do it? Both are equally important, IMO.[code]...

I was working through Beth Massi's article, "Using TableAdapters to Insert Related Data into an MS Access Database" here: http:blogs.msdn.co...s-database.aspx
And I configured the TableAdapter exactly as shown by Beth, yet I am getting an error here:
Me.OrderDetailsTableAdapter.Update(newOrderDetailsRow) The Error says: "You must enter a value in the 'OrderDetails.CustomerID' field."
I am using this code for inserting a related record:
Namespace MyDataSetTableAdapters
Public Class AccessIDHelper
'<summary>
[Code].....
I am not able to insert and move on as I am getting the error marked above.
What could be possibly wrong with the above code and why is this giving an error ?

I have this piece of code wich works perfectly when inserting records into one table using records from another table. My question is that now i need to create another table by using records from 3 other tables (tables are related). Can i use aliases on the column names, like on Oracle SqlPlus? How will be the syntax of the 'INSERT INTO SQL statement?
Dim MyConn As ADODB.Connection
Dim MyRecSet As ADODB.Recordset
Dim tmpSQL As String
MyConn = New ADODB.Connection

I setup a strongly typed dataset using the DatasetDesigner in VB2010. I am using the TableAdapter.Insert method to add data to an Access table. Before the data is inserted I need to validate the data using the DataTable RowChanging event.
How can I get the DataTable RowChanging event to fire when using the TableAdapter.Insert method?
Here is an excerpt of code I have so far:
When the Insert method runs, it does not fire the datatable RowChanging or NewRow events.
Imports System.IO
Imports System.Data.OleDb
Imports System.Data

I only process the File name.The file name already contains all the information I want.[code]I decode the name and insert into the table with columns (DateTime, Location, User). I'm not opening the file. It's a Jpg image. After processing it, I need move the file to a folder based on the UserName.[code]The function will be called for every single file found. Is this most efficient way? Looks like it's is very slow. I need to process about 20~50 files/sec. Probably a stored procedure?

With the code above, I'm trying to create and insert records into a MySQL database. The issue here is that not all records are inserted. If the XML document I'm reading from has 80 records, only 40, or 66, or some other number get put into the database. I'm guessing this is because the code is trying to insert the records faster than the database can handle them? What would the correct way to make sure the record is in the database before moving on to the next one?

I'm in the process of making 2 database applications. Each are encountering their own set of errors. For this particular application, I have a "Main Menu" form that has a button which loads an "Add Record" form. The user is suppose to be able to insert new records here via text boxes, but the problem is that record with the first primary key is being displayed in the text boxes when the "Add Record" form loads. I have no idea and can't find anything anywhere about making these boxes blank. I'm connecting to the .accdb through a dataset.

Relatively new to VB.NET coding. Am creating a pretty simple console application that needs to insert over 50,000 records into an Oracle table (OleDB connection). I tried 3 different methods so far: Individual INSERT, insert using a dataset, & using INSERT ALL (commit every 25 records due to # of columns). It seemed like most articles/posts I read recommended the dataset approach, but the INSERT ALL code was definitely the fastest by far.

I have the following code which inserts a record at a time, instead I want to insert all the records at ago instead of calling the routine by clicking a button to insert a record a time. Presently, if I have 3 records I have to click the button 3 times to manage to insert all the records. I want to perform only one click to insert all 3 records.I have a For statement but it seems it's NOT doing it.

I am rather new to vb.net using SQL CE. This is using 3.5 framework. I am trying to use a button to insert records into a table in a SQL CE database. Rowsaffected returns a value of 1, but when I preview the data, the row is never inserted. The sql statement I am using uses hardcoded values only because I am trying to get this to initially work. Once I can get the insert statement to work, it will use variables based on user input.
Here is my code that I am using:
Private Sub cmdInsert_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdInsert.Click
Dim connstr As String
Dim rowsaffected As Integer
connstr = ("Data Source =" _
+ (System.IO.Path.GetDirectoryName(System.Reflection .Assembly.GetExecutingAssembly.GetName.CodeBase) _
+ ("jhepfner.sdf;")))
[Code] .....
The original database that I am using is c:jhepfner.sdf. When I run this, connstr shows:
Data Source =Program Filesjhepfnerjhepfner.sdf;
In server explorer, it shows the connection string as:
Data Source=C:Documents and SettingsCompaq_OwnerLocal SettingsApplication DataTemporary Projectsjhepfnerjhepfner.sdf

I have a datatable populated from an SQL Server 2008 database table. I created a DataAdapter with a commandbuilder to manage the updating, inserting, and deleting of records. The Updating and Inserting work as expected. However, Delete does not. The code runs through just fine without any errors. The number of records in the datatable after the row is deleted even reflects the deletion. The DataAdapter.Update works fine without any exceptions. But when checking the actual table in the SQL DB the deleted record is still there.Here are the parts of my code that deal with this table.

I'm creating a project using Microsoft Access 2007 & Visual Basic 2008.I have two tables in my database, Staff and Training Attended. The Training Attended records of Staff are displayed in datagridview, residing in a different form from the Staff detailsWhat my program does is, it will display all of the Staff's list of Training Attended in datagridview once I click the button in Staff form. I've succeeded in retrieving the records. using bindingsource.filterThe problem is that I can't insert/update/delete records in the Training Attended datagridview. it keep giving me this error: Update requires a valid UpdateCommand when passed DataRow collection with modified rows.
