I've only been doing this a few weeks but been struggling with getting some simple commands working.I'm trying to get an insert into statement working, it works fine with a table in access 2007 that is text fields, however it wont work once I use a number field. Here is my code which doesn't work.
Private Sub btnInsert_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnInsert.Click

I've got results in a loop format from a XML file, I want to either insert them into my SQL database or update them if they are already there. My question is more around lodgic, do I have to
1. Get each item.
2. Do a search for it and see if it's in there.
3. If not add
4. If so update
Or is there a quicker way because with 200 records at a time, search then update/insert will slow down the process.

i am using MsAccess as database.insert/edit/delete commands are working perfectly in my code. the problem is that if i insert a record it is definitly inserted in table in MsAccess but that cannot be seen on runtime. To see that inserted record i have to close MsAccess Table to verify that the record is inserted there. And also I have to stop debugging and then restart debug to see that the record is being displayed in Datagridview. How i can changes in records can be seen on runtime in DatagridView as well as in the MsAccess table on runtime.

looking at the code below I have a form that is inserting data from text boxes and a datetimepicker into my database.If Date.text and Shift.text already exist in a row then UPDATE instead of INSERT a new row?
conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=database.mdb;"
da.SelectCommand = New OleDbCommand("SELECT ID, idate, icomment, ishift FROM table")
da.SelectCommand.Connection = conn

I have made a small form where I have bound textbox with records from database.Although my code for inserting and updating the record seems fine and working. But when I view the database, tables i see no inserts/updates made there. But When I run my application again, I see the records in the bound textbox but only for some seconds (for around 1 and half minutes), although they are not shown in the database (tables) actually.
When I close the application and run again it after 1-2 minutes there are no more records bound to the textbox, since no records at all.How can this be possible. I don't have any idea what's going on.
I have been using visual studio 2008 and sql server.Code I have been using for ::
'Update the Records Private Sub btnUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdate.Click

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.
Dim rowcount As Integer = AccessDataSet.AccessTbl.Rows.Count
Dim y As Integer = 0
For x = 0 To rowcount - 1
txtRow = AccessDataSet.AccessTbl(y)
If IsDBNull(txtRow(7)) = False Then

I have a gridview that is set to a sql datasource, it is generating the columns automatically. If I add a column to the table it is referencing, it will draw that column and display it, but it does not update the insert/update commands to include the new column. Is there any way have it rebuild those commands automatically?

I have a gridview in which when I click edit, update, and cancel button comes. I have a variable named status. If status=false then update should change to insert and if status=true then update should be update itself.

<ItemTemplate>
<asp:LinkButton ID="lnkEdit" runat="server" CommandName="Edit" Text="Edit">

I am trying to re write a VB6 program using MS Access, many years ago, using VB 2010 express and SQL server 2008 R2 Express. I have a database with several tables, which I created using the designer. I am able to connect to the database and select data and display it in textboxes etc in vb code. What I have not been able to in code is to INSERT rows DELETE rows or UPDATE any data in the tables. I can do any of these operations using the Query Designer, but I want to do it in code. I can post some code if necessiary, but I thought it might just be some property that I had not set in the designer.

I get a "Syntax error in INSERT INTO statement" on the da.update line. The bulk of the code is copied from a working section of the program, I have just added the "newrow" stuff. I am pretty confident I have the names of all the fields correct.

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

I want to auto update the third column that if I delete the value of one of first two columns the third column will be affected.

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.
