    Property Value

    The number of rows changed, inserted, or deleted. -1 for SELECT statements; 0 if no rows were affected, or the statement failed.
    Remarks

    System.Data.Common.DbDataReader.IsClosed and RecordsAffected are the only properties that you can call after the SQLiteDataReader is closed.

    Example
    This sample shows how to find out how many rows have been affected during last query. You can do it even if the SQLiteDataReader has been closed.
    public void ProcessReader (SQLiteDataReader sqReader)
    {
      if (!sqReader.IsClosed)
      {
        while (sqReader.Read())
        {
          for (int i=0;i<sqReader.FieldCount;i++)
          {
            Console.Write("\t"+sqReader[i]);
          }
          Console.WriteLine();
        }
      }
      else
      {
        Console.WriteLine("The DataReader is closed. Rows affected in last action: "+sqReader.RecordsAffected);
      }
    }
    Public Sub ProcessReader(ByVal sqReader As SQLiteDataReader)
      If Not sqReader.IsClosed Then
        Dim i As Integer
        While sqReader.Read()
          For i = 0 To sqReader.FieldCount - 1
            Console.Write(" " & sqReader(i))
          Next i
          Console.WriteLine()
        End While
      Else
        Console.WriteLine("The DataReader is closed. Rows affected in last action: " & sqReader.RecordsAffected)
      End If
    End Sub
