I have a query which returns results of data, which runs on a frequent basis. The new table will contain results of the old table as well but I only want to take whatever is in new in the most recent run of the new table and send that as an email. I already have the line for the email and trade data but just need a way to be able to:

* display the results of the new table to be emailed
* save the complete results of the new table to be used in the next run of the query

e.g.

Old results: `tbl`

```
| idx | name  | age | 
| 0   | Tom   | 30  |
| 1   | Jerry | 25  |
| 2   | Bob   | 30  |
| 3   | Ken   | 45  |

```

New results: `tbl`

```
| idx | name  | age | 
| 0   | Tom   | 30  |
| 1   | Jerry | 25  |
| 2   | Bob   | 30  |
| 3   | Ken   | 45  |
| 4   | Sam   | 40  |

```

output required:

```
| 4   | Sam   | 40  |

```

and then save the New results to be used in the next run

Thanks! :)
