00:00:02,230 --> 00:00:08,290
We saw how we can insert, update and delete things in the last lecture and therefore our flight data are

2
00:00:08,290 --> 00:00:12,720
now is empty as we can confirm if we run find, nothing is returned.

3
00:00:13,120 --> 00:00:14,720
Now time to add something again

4
00:00:14,830 --> 00:00:17,370
and there was this file you found attached earlier,

5
00:00:17,470 --> 00:00:20,110
you can find it attached again to this lecture.

6
00:00:20,110 --> 00:00:25,630
It holds an array of json documents and now I want to use the entire array,

7
00:00:25,630 --> 00:00:30,490
so make sure to copy the entire file content and then back in the shell,

8
00:00:30,790 --> 00:00:39,100
let's again access our flight data and use insertMany now. insertMany now allows you well as the name suggests,

9
00:00:39,130 --> 00:00:46,360
to insert many elements and this is actually not done by adding many elements separated by commas but

10
00:00:46,360 --> 00:00:47,990
instead by passing an array,

11
00:00:48,130 --> 00:00:50,210
so exactly the kind of data we got.

12
00:00:50,530 --> 00:00:54,240
Let's delete the closing parentheses and paste that in

13
00:00:54,400 --> 00:00:59,980
and then add the closing parentheses after the closing square brackets. And with that if you now hit enter,

14
00:01:00,330 --> 00:01:00,900
you see

15
00:01:00,940 --> 00:01:04,700
this was accepted and it inserted two IDs

16
00:01:04,900 --> 00:01:06,790
and there you also see this order,

17
00:01:06,790 --> 00:01:12,160
it automatically keeps which I mentioned. It's almost the same ID but the second ID has a c at the

18
00:01:12,160 --> 00:01:17,410
end and therefore, it will be ordered after the first element which makes sense because it was the second

19
00:01:17,440 --> 00:01:18,420
element inserted

20
00:01:18,520 --> 00:01:26,030
so mongodb keeps the order here. And now if we again access our flight data and find it all and pretty

21
00:01:26,040 --> 00:01:26,770
print it,

22
00:01:26,900 --> 00:01:30,930
here is our flight data with the automatically added IDs.

23
00:01:31,420 --> 00:01:35,860
So this is now insertMany and now you saw both, insertOne and insertMany,

24
00:01:35,860 --> 00:01:40,530
you also saw updateOne and updateMany and deleteOne and deleteMany.

25
00:01:41,020 --> 00:01:45,730
There is another thing I want to show you though and that is related to finding data.
