Dataadapter with CommandBuilder - Sql Server

The DataAdapter is a part of the ADO.NET Data Provider. ADO.NET DataAdapter is used to manage four separate Command objects. The InsertCommand, the UpdateCommand, and the DeleteCommand properties of the SqlDataAdapter object update the database with the data modifications that are run on a DataSet object. The SqlCommand objects that are assigned to these properties can be created manually in code or automatically generated by using the SqlCommandBuilder object.

The SqlCommandBuilder opens the Connection associated with the DataAdapter and makes a round trip to the server each and every time it's asked to construct the action queries. It closes the Connection when it's done. The following Source Code demonstrate how to use the SqlDataAdapter object to update a SQL Server database with data modifications that are run on a DataSet object that is populated with data from a table in the database using SqlCommandBuilder object.




Imports System.Data.SqlClient
Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim connetionString As String
        Dim connection As SqlConnection
        Dim adapter As SqlDataAdapter
        Dim cmdBuilder As SqlCommandBuilder
        Dim ds As New DataSet
        Dim sql As String
        Dim i As Int32
        connetionString = "Data Source=ServerName;Initial Catalog=DatabaseName;User ID=UserName;Password=Password"
        connection = New SqlConnection(connetionString)
        sql = "select * from Product"
        Try
            connection.Open()
            adapter = New SqlDataAdapter(sql, connection)
            cmdBuilder = New SqlCommandBuilder(adapter)
            adapter.Fill(ds)
            For i = 0 To ds.Tables(0).Rows.Count - 1
                ds.Tables(0).Rows(i).Item(2) = ds.Tables(0).Rows(i).Item(2) + 100
            Next
            adapter.Update(ds.Tables(0))
            connection.Close()
            MsgBox("Data updated ! ")
        Catch ex As Exception
            MsgBox(ex.ToString)
        End Try
    End Sub
End Class
