I am using a blank dataset which I fill, then update in the database.
I was wonding if there was a way to figure out the "ID" column which is an insert id after the update.


        Dim myTest As DataSet = LoadBlankTest() 'this returns a dataset select * from tests where 1=0
        Dim drTest As DataRow = myTest.Tables(0).NewRow
        drTest("description") = testName
        drTest("offset") = offsetValue
        dataAdapter.Update(myTest) 'This works, but dataset does not contain the id number after this


    Public Function LoadBlankTest() As DataSet
        LoadBlankTest = getDataSet("SELECT * FROM Tests WHERE 1=0")
    End Function

    Public Function getDataSet(ByVal selectString As String) As DataSet
        Try
            Dim myData As New DataSet()
            Dim myConnection As New OleDb.OleDbConnection(connectionString)
            dataAdapter.SelectCommand = New OleDbCommand(selectString, myConnection)
            Dim CB As OleDbCommandBuilder
            CB = New OleDbCommandBuilder(dataAdapter)
            dataAdapter.UpdateCommand = CB.GetUpdateCommand()
            dataAdapter.Fill(myData)
            getDataSet = myData
        Catch ex As Exception
            MsgBox("Database Error")
            getDataSet = Nothing
        End Try
    End Function

use @@identity if you are using Access 2000 or later. Does not work with Access 97

are you sure that will work?

I am not using an insert id, I am updating a dataset.

Sorry about that.

Since there was no clear cut answer and I didn't think it would help out anyone else, I gave the question a c.
When I do a search, I only try to look at  the 4 star answers.
I feel like anyone looking at this post would just be wasting their time.
It could be because of my vague question, I don't dispute that, but it is just cluttering the site.
I was grading that way more for the integrity of the knowledge base than for effort.

I was trying to get the dataset to hold the insert id which could be used in the code above.

"SELECT @@IDENTITY FROM Tests" does not necessarily return the insert id of what I am doing.
It gets the last insert id on the table, but not necessarily on the code above.
It is also database dependent.

It also doesn't allow me to use the dataset I currently have.

I would usually try to delete the question, because I think this site is a valuble resource.
