ingresar listview a BD error!

[Aquaventus]

son columnas y no subitems.... entonces seria :

Código c#:

For i = 1 To Ltver.Items.Count
  myCmd.CommandText = "INSERT INTO detalle VALUES('" & numeroboleta.Text & "','" & Ltver.Items.Item(i).ToString & "','" & Ltver.Items.Item(i+1).ToString & "','" & Ltver.Items.Item(i+2).ToString & "','" & Ltver.Items.Item(i+3).ToString & "');"
     leelo2 = myCmd.ExecuteNonQuery()
    Next
