Learn how to create your first SQL Notebook | Data Exposed


>>Hi my name is Alan Yu, a Program Manager on
the SQL Server team. In today’s how to video, I’ll be covering a Notebook
viewer in Azure Data Studio, creating your first SQL Notebook, and how to interact with
and use your SQL Notebook. Notebooks are single
documents that comprise of rich text cells like Markdown and executable
code cells like Python. Notebooks can also
include visualizations, code output, and even GIFs. Notebooks are a very popular tool in the data scientist
community for use cases, such as interactive tutorials, running daily analysis, or telling
stories using data models. Azure Data Studio supports Notebooks, including a special kernel
known as the SQL Kernel. With the SQL Kernel, you can now create
Custom Notebooks using both T-SQL or PostgresSQL. Let’s start off with our
SQL Notebook toolbar. As you can see, you can
easily add a code cell or a text cell and then quickly be able to write things and
see the preview of it, and then you can also
delete your cell. As mentioned before, we have the special SQL Kernel
using this Notebook, but you can also easily change
it if you wanted to have a Python Notebook or
Spark Notebook, etc. Next, you see this component called, “Attach To” and this is where
you actually make a connection to your SQL Server instance where your Notebook
will be run against. So for now, I’m running a version
of SQL Server 2017 locally. Next, we’re able to make sure
that our Notebook is trusted, have the ability to run all
the code cells if a Notebook, and then also be able to
clear all the output from those code cells easily
from a click of a button. So for the purposes of this tutorial, we’ll be looking at this tutorial from our
official SQL Server Docs, where you can create and query database objects and essentially
learn how to write T-SQL. This is a very important use
case of Notebooks where you can help educate people of how
to get started on your team, or just generally learned
about SQL itself. So what we’re going to do here is essentially copy over this tutorial, which I have here in
Visual Studio code. So I’m going to copy over the text component which
is written in Markdown, and I’m going to add a text cell. So as you can see here,
several things appear. So to start off, Markdown is a rich text language for
converting text to HTML. There are many resources online
to learn more about Markdown, but for now I’ll show some of
the components of a text cell. So for example, one of the
components of Markdown is that, if you add a pound sign this
indicates that is the header, and you can see that there’s
a preview as you type here and it will automatically
show in the information below. So it’s easily you can tell what
is the output of your Markdown. So after you are comfortable with providing the instructions
at the top of your Notebook, you can next add a
code cell by clicking this button here or the
toolbar as mentioned before. So I’m going to add a code cell, and essentially this will run a T-SQL command for
creating your database. Then if I want to execute
this cell right now, I could click the “Play”
button to run the cell. So I can continue this process
of combination of text cells and adding code cells in a repeated pattern but
the save all of us time, I already created this
Notebook before and we can now use this to explore what
exactly this tutorial includes. So you can see that it
starts off by creating a table, creating a database, and this tells you how to get
started with creating a database, and then it will
eventually go down to inserting actual data
into your table, and then eventually being able
to select that values as well. So for this Notebook, actually is okay that we
already run all the cells at once so then we could go around
and play with the tutorial itself. So in order to execute
all the code cells, you could click “Run Cells” here, and then the Notebook
will just start running all the code cells and
generate output for it. So for example, you see there
is a select statement here and you can see that the output is nicely printed out
from our results grid. In fact, if you wanted to share
this data in another format, you can “Right-click” on it and then “Save” it in these
very common formats, such as a CSV, and we’ll
save it really quick here. You can see that you will
get the same results on a CSV file or for the other
supported file types. So in addition, if you
wanted to rerun the cell, to make sure that like any
changes to the database occurred, you can rerun it and you can confirm that all the
data still is the same. So there’s a lot of use
cases that you could do with creating your
own SQL Notebooks. Not only can you be using this
to help educate people and have a step-by-step process as they
walked through the tutorial, we can also imagine
using this for running daily jobs and just have
all the basic configuration in there and then include Markdown
instructions so that you can easily understand when to execute
these different pieces of T-SQL. So there’s a lot of fun things
you can do with Notebooks. This will just help you get started with creating
your very first one. So in order to help you get started with creating SQL
Notebooks after this video, I’ve created these awesome
next steps for you. You could first start
off by downloading Azure Data Studio at
aka.ms/getazuredatastudio. You can also visit our Docs, where we have specific
documentation explaining a lot of the concepts that I
talked about in this video, and then follow us on
Twitter for any of the latest updates as we continue to grow this feature
and Notebook itself. Please try out SQL Notebooks today. Thank you [MUSIC].
