💻 Setting Up PostgreSQL in Visual Studio Code
The paragraph explains how to set up PostgreSQL with Visual Studio Code (VS Code). It starts by opening VS Code and navigating to the extensions section, where the user searches for a PostgreSQL-related extension. The tutorial highlights the selection of an extension with a 4.5-star rating and mentions the installation process. After installing, the paragraph describes configuring a new database connection by entering server details like localhost, username, and password, and confirms that PostgreSQL is ready to be used in VS Code.
🗂 Accessing Databases and Tables in PostgreSQL
This part focuses on connecting to a local PostgreSQL server in VS Code. It guides users through setting up the correct port number (5432) and demonstrates accessing a database. Once connected, the paragraph shows how to view available tables in the database and how to run a 'Select Top 1000' query to display table data in the editor. It emphasizes the ease of querying a PostgreSQL database within VS Code.
📝 Running SQL Queries and Viewing Results
The paragraph goes on to discuss executing simple SQL queries, specifically a 'SELECT * FROM country' query, within Visual Studio Code. It describes the process of writing and running queries, displaying the results of table records, and highlighting how easy it is to interact with the PostgreSQL database inside VS Code.
🔧 Choosing the Best PostgreSQL Tools for VS Code
The final section gives advice on which PostgreSQL tools or extensions to use with VS Code. It mentions another extension provided by Microsoft, but the author doesn't recommend it due to its lower rating despite having many downloads. The suggestion is to stick with the extension previously installed, which is more reliable. The video ends with a thank-you note, encouraging viewers to try the recommended tools.

Transcripts
lecture I am going to discuss what how
to connect positively and square with vs
gold so opening the visual studio code
fast
so this place so you can see extension
is there click on the extension then
there you need to search post create
and you can see this is here 4.5 star is
still
and you can see the number of stars
so I'm going to install this one because
it has two not good number of
installation and could restart software
installation you can see there's the
icon that's created Square now after
that click on this plus so this plus so
you need to add
or the database so here first we need to
go the server name that is so killing
the localhost press enter
and here the user we need to give so
that is the post curious
and after that we need to give the
password of this one
and press enter 5432 that is good for
the port number
and
extender connection so the database so
database so that's the writing here post
case
that's come there and no that's fine and
now you can see this is come there
localhost here post case
public and there are two
or tables are there inside so here you
can see select the top thousand so now
top 1000 or record so that's a display
and after that when I start click then
you can perform any kind of query this
place
so now I'm going to write two simple
select statement and select
a start from
so we have the table called country so
let's write Here country that right
click then you can see it on query
option click on there then you can see
the table records inside whatever the
record inside the country table that's a
display so this is the most simplest way
we can here connect to or postcreate SQL
Visual Studio code now if I go on this
extension then you can see there is so
post query SQL that's also yeah that you
get so from the Microsoft but a number
of download is good but only two stories
there so I'm not going I'm not
recommending to use this one so you
should try this so
