00:00:00,300 --> 00:00:01,050
Hello again.

2
00:00:01,050 --> 00:00:02,250
Welcome to the next section.

3
00:00:02,580 --> 00:00:05,080
So first of all, hopefully you can see me.

4
00:00:05,100 --> 00:00:06,510
I am wearing camouflage.

5
00:00:06,540 --> 00:00:09,160
I know that can make it a little challenging, but I am here.

6
00:00:09,180 --> 00:00:10,470
Not just a floating head.

7
00:00:11,370 --> 00:00:14,070
With that said, this section is.

8
00:00:14,430 --> 00:00:16,050
Well, I keep saying important.

9
00:00:16,050 --> 00:00:20,010
Everything is important, but this section is really taking us back to basics.

10
00:00:20,370 --> 00:00:20,900
In a way.

11
00:00:20,910 --> 00:00:22,320
We're talking about data types.

12
00:00:22,320 --> 00:00:28,200
So if you remember way back, I don't know, Section three ish, I mentioned that we would come back

13
00:00:28,200 --> 00:00:32,549
to data types when I introduced VAR chart of our car, however you want to say it.

14
00:00:32,910 --> 00:00:36,540
And integers are two data types we've been working with, which are great.

15
00:00:36,540 --> 00:00:40,140
They're very useful, but there is a big world outside of those.

16
00:00:40,140 --> 00:00:42,660
What about things like decimals?

17
00:00:42,660 --> 00:00:47,970
How do we store currency price information where we have information after the decimal?

18
00:00:48,090 --> 00:00:52,590
How do we store things like dates and time?

19
00:00:52,590 --> 00:00:56,970
Well, make word my watch go things like dates and times.

20
00:00:57,180 --> 00:01:03,150
There's a lot of information that we need to store that doesn't neatly fit into our chart or integers.

21
00:01:03,150 --> 00:01:08,790
So this section is all about introducing and surveying those kind of different data types.

22
00:01:08,790 --> 00:01:13,980
And I could have done this early on in the course, but I've done it in the past like that in person.

23
00:01:13,980 --> 00:01:19,350
And I find that students get too bogged down just worrying about all the data types when really they

24
00:01:19,350 --> 00:01:22,920
need to be focusing on things like create tables and insert statements.

25
00:01:23,160 --> 00:01:24,810
That's the focus of SQL.

26
00:01:24,810 --> 00:01:28,860
In my SQL, we can insert or we can add new data types easily.

27
00:01:28,860 --> 00:01:30,300
So that's what this section is.

28
00:01:30,300 --> 00:01:31,890
We have the two we've been working with.

29
00:01:31,890 --> 00:01:37,650
Now we're adding a bunch more, a ton of exercises here, nothing complex with our data.

30
00:01:37,650 --> 00:01:40,560
We're not using any brand new data set.

31
00:01:40,890 --> 00:01:43,620
All we're going to focus on are the data types we'll see.

32
00:01:43,620 --> 00:01:49,260
In particular, we'll focus on dates, times, date times, timestamps, all this terminology.

33
00:01:49,260 --> 00:01:53,010
It gets a little crazy, but hopefully we can simplify that in this section.

34
00:01:53,160 --> 00:01:54,150
All right.

35
00:01:54,150 --> 00:01:55,890
See in the next video.
