I'm trying to delete a number of records in a table from the last and forward. My idea is to use sql like this: delete top " & variable & " * from table where ID = something It gives me a general sytax error. Is it at all possible? Fuga. Edit: I also have the order by statement there. I just forgot to put it in the question.

I'm looking for a simple example in VB2008 code.I have the Northwind DB installed on one of our SQL servers.
I've worked with the Datagridview on serveral occasions but never used its update,delete or add functions. I've Googled around the web, but could not find a simple example.
Whats the best way to do this and implement it using LINQ?

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 Form1 that is the main application form, that display certain data from a database. Then I have Form2 that add/delete data from a specific table in the database.My problem is, When I add data to the database, and save it, it work fine, But, it does not reflect on the main form, after I close Form2. Only when I exit the application, and open it again, it shows. Is there a setting or something I need to do to update/refresh the info added so I do not need to restart the application?

My apologies I have posted this in the wrong catagory It should be in VB.net, my mistake)Hi guys I posted this question at the end of another topic I started but I think it will be over looked as the origional topic was solved of the dreamincode community You must all be getting sick of my quexstions by now haha I suppose you don't learn if you dont ask.
Anyway I have used the delete sql method to delete data from a database, I want to refresh the data in the form after the record has been deleted. Do I have to close the form and then open an new instance of it? or is there another way I can refresh the data?

How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.
Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click
'Function declarations

The above is more or less the complete question. I have created a table in the VB 2010 Database Explorer but I cannot for the life of me work out how I can get this copied or created into the underlying server. It is not appearing in the underyling serverand when I run the code of course I ge "invalid object <tablename>" I have data as well in the table that appears in Database Explorer. I think I have missed something fundamental in my overall conception of using VB 2010 Express with SQL Server Express in that I don't know if I have a local copy (that isn't then mirrored on the server), or what (the ____ have I got)? An article that explains the overall relation of Database Explorer to the underyling Server would be great as well
