So you can see that it has

nicely categorized all of the parts.

This is very helpful,

either using numeric values like I have shown or

text values so that you can either display it on the screen

or use it to build a bare condition

or mark it out to another table.

This brings us to the end of our part one of the SQL journey.

So far, we have been building queries where

all the data sits in one table,

and then we are doing operations on that data.

In the subsequent part of this video,

we are going to look at joins so that you can take data that is in

multiple tables and then combine that to create one output.

Let's go.

In the joins part of this video,

I'm going to show you some practical examples

and briefly explain what is what.

But if you want to learn a little bit more about how joins work and

how to use them for many practical scenarios,

you will need to do a little bit of further study.

I'll talk about some resources for learning

SQL later on at the end of the video.

But for now, let's go and build some joins.

Before I do that, I just want to save my SQL file,

because then I can come back and refer to

these queries or I can share these examples with you.
