Let's discuss the process of **DELETING** data from the database. Return to our Python Console and give the **delete** query a try. Deleting is a simple process – you just need to invoke the database object and use the `delete()` method instead of `add()`. Then, pass the object you want to delete.

If you've closed your terminal or Python Console, don't worry. You can simply <u>import db, Recipe, app</u> to get back on track.

``` python
recipe = Recipe.query.get(4)
db.session.delete(recipe)
# we haven't commit this change yet.
db.session.commit()
# now it should work now and its gone.
Recipe.query.all()
```
It's pretty much for deleting just to know `id`.
