hey guys in this video I'm going to show
you how you can use your Visual Studio
code to query your post gray SQL Server
so let's get started so first of all
open the extensions section in Visual
Studio code and search for the extension
called SQL tools and the first result
most probably which will appear here
will be this one which is for SQL
tools now this extension works with many
other s SQL based database systems like
MySQL postr SQL Microsoft SQL Server so
the full list of supported database
systems you will be able to see in the
read me section of uh this extension so
first of all click on install which is
going to install this
extension now once this extension is
installed there is a new icon which will
appear here on the left hand bar R which
is for SQL tools so I'm going to click
on this uh icon here and let me close
this uh extension and then I can click
on new connection to create a new
connection now in order to connect to
the post gray SQL or any other database
system this SQL tool extension requires
the desired driver extension for that
database system so in our case we will
will be connecting the post gr SQL right
so we need the driver extension which is
for post G SQL so once again go to the
extensions and then once again search
for SQL tools and under SQL tools you
will be able to see more options which
are related to SQL tools so for example
SQL tool for MySQL Maria DB SQL tools
for uh sqlite and we can also o see the
SQL tools for postc SQL which is the
required driver we need to connect to
the SQL Server so just install this
extension also if you're using any other
database then you need to install the
required driver for that database which
is related to SQL tools so once this uh
is installed we can once again click on
SQL tools option here and now when I
click on add new connection I can see
these two options I will click on post
gr SQL here and then I need to provide
the configuration of my post gray SQL
Server so that I can connect to my post
cray so here the connection name you can
uh give any name here I'm using the post
CR locally so I'm going to just uh name
my connection as PG local here and then
you can also provide a connection group
I'm going to leave it as default
now you can connect via the server and
Port socket file or connection string
I'm going to use the first option which
is server and the port and then you need
to provide the server address if you are
running your postgre SQL locally just
leave it as Local Host if you're running
your post gr SQL server on some remote
machine then provide the proper IP
address of that machine and then the
post Port the default port for
connecting to the post SQL Server is
5432 if you are using some different
port for your MySQL server just provide
that
here now in order to connect to your
postre SQL Server you need to provide
the name of the database which already
pre-exist in your MySQL server so let's
say I have this database which is called
demo which I have already created in my
MySQL server so I need to provide the
database name I want to connect to so
here you need to provide the username
which you use to connect to your MySQL
server generally uh if you have
installed postra freshly then the
username will be postrace but it can be
different also which depends on the
settings of your post G SQL
Server now here in the password section
you have few different options like uh
ask on connect use empty password and
then you have save as plain text in
settings so I'm going to use the last
option which is going to save my
password as the empty setting just for
the Simplicity but if you are concerned
about the security then I will ask you
to use uh the first option or the second
option here so I'm going to choose the
last option which is save as plain text
in settings because I have my post
server running on my local machine so my
password is really simple here and then
when I move down a little it says node
PG driver specific option if you're
using SSL then you can uh enable the SSL
from here also you will be able to see
these multiple options like query
timeout statement timeout connection
timeout if you want to give these uh uh
settings then you can give all these
settings from here I'm going to leave
everything as default and then you have
this connection timeout option so I'm
going to give this connection time out
as 30 here and now I have given all the
required configurations so here I have
the option to save my connection but
before that we can also test our
connection by clicking on the test
connection button so when I click on the
test connection button I can see
successfully connected that means my
connection works so I can click on Save
connection now as you can see the list
of connection will be listed here and
your configuration in the form of Json
is listed here so you can see my
password for my local post gr is root
and uh all the other configuration is
listed here now in order to connect to
your postra server you can just click on
connect now or you can click on this
icon here which is for connect you can
also see the query history which we are
going to see little bit later when we
provide some queries here so I'm going
to click on this connect icon here which
is going to connect to my post SQL
database and it's going to give me this
kind of interface where I can run
queries on my database I can also expand
this connection where I will be able to
see my database which is a demo and then
if I have some uh tables I will be able
to see the list of tables here so I
already have one table here which is for
the names if I want to create new tables
I can provide the query to create those
tables so let's say I want to create a
new table here in addition to the names
table so I can uh provide this query
which is create table if not exist the
table name will be users and it has
three columns ID username and email the
ID is the primary key here now in order
to run this query you can can click on
run on active connection and once I uh
click on this it's going to show me this
kind of uh tab here which is for my
query and then when I refresh uh this
connection here so I'm going to click on
refresh here then I can see my users
table and then I can also see that I
have these three columns in my table
right now if I want to see the content
of this table I can right click on this
uh table and then click on show table
record right now I don't have anything
so I can see the blank uh table here but
once I have some data in this table I
will be able to see the records so now
let's insert some data into the table so
I'm going to provide this query for
inserting the data into my post crit
table which is insert into users user
name comma email and then I am going to
add these three row in my table now if
you want to uh run a particular query
and not the whole SQL script then you
can select your query here and then
right click on your query and then you
have this option which says run selected
query here and it's going to run your
selected query and once that's
successful I can once again right click
on the users table and then click on
show table records and now I I can see
three records here which are added to my
table
right so this is uh the SQL session
which you can save uh for the later
references also you can see all the
queries which are executed in the query
history here now let's say I want to
select the record via the query and not
by right clicking on this table I can do
that also so let's say when I type some
query here let's say SE this extension
is going to give me the options for the
auto complete for example select
srix from users and then I can once
again select this and then right click
and then click on run selected query and
it's going to show me the table
records now if you want to see details
about your table or database you can
once again right click on your your uh
table or the database and then you have
the option to describe your table it's
going to describe what are the columns
which are available in your table and
what are their data types and uh other
constraints about your columns you can
also add a new insert query so just go
to the end of your SQL script and then
right click on your table and then you
can click on generate ins insert query
is going to give you the sample insert
query for you so as I mentioned ID is
not required in my table which Auto
increments so I'm going to remove that
but I can change the values for the
username and email right so let's say a
username I'm going to leave it as
default and email let's say I'm going to
say email atate gmail.com
and then I can once again execute this
uh query you know the drill and once I
do that the data is inserted and I can
see the new data here like this which is
the fourth row now let's say you want to
change the configuration of your SQL
connection let's say your Port has
changed and you want to change the SQL
connection just so just right click on
your connection here and then click on
edit connection and you will will be
able to edit your connection you also
have the option to delete your
connection or you also have the option
to disconnect from your current
connection right so when I click on
disconnect it's disconnected and now I'm
no longer connected to my post csql
server but the configuration is there so
let's say at the later point when you
want this connection once again click on
connect and it will connect once again
this is how you can
use Visual Studio code to connect to
your postc SQL Server then query your
postc SQL server using visual studio
code that's it for this video I hope
you've enjoyed this video and I will see
you in the next video
