i'm querying 2 tables from an access 2007 database + i've worked out the SELECT statement which works ok:
vb
"SELECT a.id, a.number, a.subjectName, a.years, a.birthYear, b.note FROM Table1 AS a INNER JOIN Table2 AS b ON a.id = b.id"
now i need the insert, update, delete commands. i'm using parameters:here are my insert, update, delete commands for a single table. how should i modify them to work with the 2 tables as shown in the SELECT statement?
vb
"INSERT INTO Table1 VALUES(@id, @number, @subjectName, @years, @birthYear)"
vb
"UPDATE Table1 SET id = @id, [number] = @number, subjectName = @subjectName, years = @years, " & _

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've just switched from classic ASP to .net and I always used the following to SELECT, INSERT, UPDATE and DELETE from my MySQL databases:
' Create db connection Function dbConn() Set objConn = Server.CreateObject("ADODB.Connection") objConn.Open "driver=x;Server=x;Port=x;Option=x;Database=x;Uid=x;Pwd=x"
I have a GridView that is tied to an EntityDataSource. Most columns are normal bound columns, but two are itemtemplates. When I attempt a delete on one of the rows I receive the following message:
"A property named 'Building1.building_name' was not found on the entity during an insert, update, or delete operation. Check to ensure that properties specified as binding expressions are available to the data source."
I'm not sure how it is possible that this isn't available, since it displays the element just fine when I'm just viewing - it just throws the error when I attempt deleting a row?
I have created a test application to display data in a datagrid, using the Dataset Wizard per the help. All fine - data is displayed.
I then added insert, delete and update queries by selecting Edit Dataset with Designer, selecting the table and adding a query for each action via the TableAdapter Configuration Wizard. In Advanced Options, all boxes are checked, and on the last screen of the wizard it says it has generated SELECT, INSERT, UPDATE, DELETE statements, table mappings, Fill, Get and update methods. The TableAdapter shows four entries: Fill, GetData(); DeleteQuery; InsertQuery; UpdateQuery. On the DataGridView Tasks page, Adding, Editing and Deleting are checked and the data preview shows data.
When I run the application, I can update, add and delete data, but this is not saved.
I followed an example from a VB 2008 Wrox book on creating, binding and updating a data set but I am having a problem. The code is supposed to automatically generate the update/insert/delete statements for me (according to the book) but when I call the update command, the data is not saved.
Here is my code
Code: Imports System.Data Imports System.Data.SqlClient Public Class FrmAddExpenses
[Code]....
After the form is loaded, I change the EntryDate field (which is a DateTimePicker) and close the form which should save the change but it doesn't work.

I am trying to do simple insert, update, delete, select statements within VB .NET to access a MS Access database. I have tried all kinds of solutions offered on the web and while the code seems to work, no rows are inserted.

I am using this code to Add rows to a SQL database, and it adds the row to the SQL database if column 7 is not null. After it adds the row to the SQL database, it deletes it from the Access Dataset, and updates the Access Database. Sometimes double rows seem to get inserted into the database, so I'm thinking there is an error in my logic somewhere here.
