When Update is called, the Data Adapter will attempt to execute each query (UPDATE, INSERT, DELETE) on every row of the Data Set that has been updated, inserted, and deleted.

Data Member = "trial1" End Sub Private Sub Button1_Click(By Val sender As System. Odbc Command Builder(adp) Dim i As Integer Try i = adp.
