大家帮忙看看这个SqlDataAdapter怎么会出现这个问题

VB.NET code

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click        Dim myDS As New DataSet        Dim TitleTable As DataTable        Dim TitleRow As DataRow        Dim connStr As String        connStr = "server=(local);uid=sa;pwd=123456;database=pubs"        Dim SQLSelect As String        SQLSelect = "select * from titles"        Dim mySQLconn As New SqlConnection(connStr)        mySQLconn.Open()        Dim mysqlda As New SqlDataAdapter(SQLSelect, connStr)        Dim mysqlcb As New SqlCommandBuilder(mysqlda)        myDS.ReadXmlSchema(Server.MapPath("AddTitle.xsd"))        Try            If IsPostBack Then                TitleTable = myDS.Tables(0)                TitleRow = TitleTable.NewRow()                TitleRow("Title_id") = TextBox1.Text                TitleRow("title") = TextBox2.Text                TitleRow("type") = TextBox3.Text                TitleRow("pub_id") = TextBox4.Text                TitleRow("price") = CDbl(TextBox5.Text)                TitleRow("advance") = CDbl(TextBox6.Text)                TitleRow("royalty") = CInt(TextBox7.Text)                TitleRow("ytd_sales") = CInt(TextBox8.Text)                TitleRow("notes") = TextBox9.Text                TitleRow("pubdate") = CDate(TextBox10.Text)                TitleTable.Rows.Add(TitleRow)                mysqlda.Update(myDS)                mySQLconn.Close()                DataGrid1.DataSource = myDS.Tables(0).DefaultView                DataGrid1.DataBind()                Response.Write("添加成功")            End If        Catch ex As Exception            Response.Write(ex.ToString)        End Try    End Sub
