That someone would take their time to make such a complete set of tutorials, and to make them available for free, is amazing. Words are not enough to express my gratitude, and my respect for you.

[calvinbarajas]

This lecture is amazing because (a) Nelson knows the exact technical terminology, (b) he is very patient and methodical, (c) covers the basics very well, (d) gives professional insight into how to use PostgreSQL.

[mercantilism]

Note for beginners:

34:50

35:44
If your password does not work, use 'postgres' for the username. Your code should look like this " psql -h localhost -p 5432 -U postgres test"
This is simply because you have not created a user account called 'user'

[rodouhy]

Thank You for using easy English. I understand a lot of.
Respect from Russia with 41 peoples.

[gunk]

The fact that this is free is insane! A very good course on Postgres. I finished this in less than 24 hours and before starting I didn't even know what 'SQL' was but now I feel like I have a solid understanding of Postgres.

[khateebanwer]

For someone who is following this tutorial currently :

1) at around 01:06:00 when you go through the SQL file in VSCode, do change the value of varchar of gender greater than 20 because Mockaroo includes more than 2 genders in randomly generated database which will throw an error during its execution through cli when not changed.

2)When using terminal (for windows users ), you might get errors during execution of sql file through cli due to path format which can easily be dealt with --> before even opening your postgres, navigate through the command line where the actual file is located and then open postgres and use \i filename.extension to execute your file.

3)When installing postgres, always provide passwords without any alphanumeric characters like "$" otherwise it will throw an error during the installation phase ( I don't know what is that error as it was really vague but this worked for me).

[Terzaghi]

For Windows users, the command 'psql' only will work if you edit the environment variables and add 'C:\Program Files\PostgreSQL\13\bin' to your path, the 13 it's the version of Postgres i've installed.

After that, the command you have to enter on the cmd or powershell is:

psql -U postgres

then it will ask for the password you set on the installation

[alexnavarro]

Seriously a 10/10 course! I sat down and watched this whole thing in a single session. I seriously appreciate your teaching style, and how well you explained everything. Thank you!

[kieranbarker]

This video is excellent. I'm only as far as creating tables (around the 41-minute mark) but it's already better than the courses I could find on Udemy! Thank you! 🙏

[gwagner]

Dude, this course was VERY GOOD! Basically binged through the whole 4 hours and felt like no time! Very didactic and well explained. THANK YOU SO MUCH FOR THIS AMAZING CONTENT!!

[madhanmurali]

Completed till WHERE Clause and you're getting straight to the point without wasting time. It is really helpful for a complete newbie like me. Thank you!

[O_o___o_]

First thank you so much for this amazing course, easy to follow and straight to the point

For those like me that will be learning on PostgreSQL 14, at 33:50 he uses the command

psql --help

for the option help and on Windows and PSQL 14 it's actually the

\? options

command that will give you the same result.

[richardish]

also just going to take a moment to appreciate how excellent this tutorial is. Clear, concise, straight to the point with real-world examples. Worked through the whole thing, and learned a TON. TYSM! ⭐⭐⭐⭐⭐

[TheAremoh]

From being scared to run sql command from command line to liking it. Thanks for this awesome video

[chriswilson]

The best PostgresQL tutorial I've seen so far.

[niyazi]

33:39 guys if you cant run "psql" command in the command line, you must add it to system environments, find the postgresql folder in C:\ and add its "bin" folder to "Path" variable in the env.

[fahansheikh]

for user using ubuntu/linux(check if postgres is preinstalled in your system) following the installation steps may cause installation of two versions of postgres simultaneously which can cause unnecessary trouble for beginners.

[LordBenjamin]

One of the best tutorials out here for PostgreSQL, the explanation is clear and the pace of it is great for beginners. Props to you.

[ugljesavojvodic]

For Windows users it's even easier, even though it seems to be confusing, just enter database name when it ask for it.
This how it looks in the shell:
-
Server [localhost]:
Database [postgres]: test
Port [5433]:
Username [postgres]:
Password for user postgres:your_pw
-
Please note when you connect for the first time you are actually connect to default one and that's why you don't enter any name, it will have name"postgres", and the owner is also default one, guess the name - "postgres".
-
When you login with all empty parameters you noted line in terminal like "postgres=#", well the part before "=#" is actually name of database, so in this default case "postgres".
-
You noted he has owner "amigoscode" (when he list all databases), it's actually added role, check postgres documentation how to add role and change owner of table.
-
Also, when you are in "postgres=#" database you can easily switch to another (that is already created, it won't create it by itself) database using command:
\c another_database_name
(example: "postgres=# \c test"
result: "test=#")
