So previously we've seen how to create, read and update using MongoDB in the Mongo shell. And now

1
00:07.410 --> 00:12.000
it's time to look at how we would delete data from our collections.

2
00:12.030 --> 00:18.170
And again if I scroll down in this CRUD documentation we've got a section that tells us how to do this.

3
00:18.340 --> 00:24.650
And you can see that the two main methods we'll rely on is deleteOne and deleteMany.

4
00:24.660 --> 00:27.370
And this is an example of how you would use it.

5
00:27.450 --> 00:35.460
So you would say db.collection name.deleteMany or deleteOne and  in the filter you would specify

6
00:35.730 --> 00:38.510
which records you want to delete.

7
00:38.520 --> 00:44.700
This is a good opportunity to translate what you see in the documentation to actual working code that

8
00:44.700 --> 00:46.750
does what you want it to.

9
00:46.830 --> 00:53.490
I want you to remove this second record that we added which is the pencil record by reading and using

10
00:53.490 --> 00:55.590
the documentation on MongoDB.

11
00:55.740 --> 00:58.160
Pause the video now and give that a try.

12
01:00.410 --> 01:01.120
OK.

13
01:01.190 --> 01:05.920
As we saw over here all we need to implement is db.collection

14
01:06.020 --> 01:15.520
.deleteOne. And we're going to say db.products.deleteOne and then we're going to provide

15
01:15.550 --> 01:21.850
the filter to find the particular record that we want to delete which in our case it would be easier

16
01:22.180 --> 01:23.850
to just specify the id

17
01:23.920 --> 01:26.950
and in this case that's going to be equal to 2.

18
01:27.220 --> 01:34.150
So now if I hit enter then you can see that my request has been acknowledged and one record has been

19
01:34.150 --> 01:35.040
deleted.

20
01:35.310 --> 01:42.070
And now if we use that find method again you can see we only have one record in our products collection.
