how can we decide to select no of column in a table as a primary key? as i saw in few table we select 2 primary key and in other we select only 1 column as a primary key.
For me It all started from this 4 hour video. This youtube video changed my life. I had no clue what SQL or what database was. I used to be an accountant and today I work as a database developer. Thank you so much. To all those people who are trying to change their careers, you can do it!
I have a question about the Mac installation /login, i feel like this might be a little outdated and especially w most people like me having the newer M1/M2 MacBooks so when I installed it , it didn’t give me any temp password or user and it was already active when I clicked on it so idk if now it just doesn’t need one to start but I’m confused on that part, anyone have same issue?
@@quadir6076I didn't understand where you have issues in registration on terminal or what? I have a MacBook and it works on m1 and op sistem is MacOs it works perfectly if you do it just like in the video Idk
@@mukhammed_kaldybai I got it , i followed the instructions exactly step by step from the vid but it’s a little outdated and the whole download process was a little different, like for example it didn’t give me a temp password I had to go into the settings and make one then go back to the terminal and follow the code steps from the vid

Two weeks ago I started doing this course thinking that it would be useful for my placements and today I'm here to let you know that because of your teaching I actually learnt DBMS and got placed in an MNC .The recruiter asked me about DBMS functions and in particular he asked me about group by function which I otherwise wouldn't have answered . I'm really grateful for you and thank you very much Sir for taking your time to explain DBMS to us.

Hi Mike, I just want to say thank you for providing such a great beginner's course for SQL and DB. I spent the last three weeks studying thoroughly and it's absolutely eye-opening for me. Thanks lot!
Hi Mike. I Stumbled upon your Python tutorial doing a general search. I started the tutorial. I am 64 and I see that you are young. Hats off to you for being young and able to teach people like me in a manner and language that I understand easily. I am also simultaneously studying your SQL tutorial. Kudos to you for repeating concepts to underline and drill them in. After so many attempts, I have finally understood the foreign key concept.

@@cibelless510 Thanks for the encouragement. Successfully completed the SQL tutorial. Finally understood how the join syntax can be written and how it works. -Cheers
I don't agree that you're too wordy, I think the conversational level makes it easy to learn. I have been an educator for decades and for me, your style is perfect, don't listen to that criticism. By the way, thank you for this one and the Python class, good stuff!
I'm on the same boat and, because english is my second language, I appreciate that he reinforces what he's saying because it helps me to better understand the concepts
you teach the entire databases course in 4 hours, that is way better and more efficient than my prof who rambles on and i don't get much out of his course for the entire 16 weeks. thanks dude! you're our lifesaver and a silent unsung hero!
Okay so am done with this course after studying it for 4 days. Before giving my review i have to declare interest that am an IT graduate so most of the concepts are not new except for Trigger concept, that was like breaking news to me 😂😂😂😂. This course covers almost every basic concepts of SQL database. What i like from the instructor was his ability to be so consice and approach a topic in a way that won't be taking too much of your time when you come back for revision especially when an interview is around the corner. But if you want to be more skilled and knowledgeable about SQL then you definitely know this is not all as the title suggests. On scale of 1 to 10, i would rate it 9. It has been good experience and i can't wait for more. God bless all of you trying to get your things right 🙏
after watching this for more than 2 weeks and preparing notes of 95 pages, I'm finally done... there are ppl who finished it in a couple days, don't compare yourself with others, take your time and just make sure you get what your doing.
I just completed learning SQL and Python in 1 weekend thanks to this guy 4h courses each. Saturday SQL/Sunday Python. Now am doing HackerRank questions. Basically wondering if I can learn 2 languages in 1 week for an upcoming technical coding test.
Thanks a bunch. I finished your 4 hour course.. I am 61 and just fascinated with these section of education. Retired engineer of the Armed Forces. I’ll share your video and channel to my son. 🙏🍾🎉
I am working as a sql developer And let me tell you when I was fresher I watch this course and when I look back I think this is one of the best sql course to start with
i had my teacher teaching dbms for 6 months and i gained nothing out of it however i do wanted to learn about Sql and i landed to this video.......this is one of the best video it teaches you from basic to intermediate it is sufficient enough to clear an interview thank you mike :))

I have been struggling in my online college course and I am probably not going to give up but I really wish i found this video sooner it is so awesome with great explanations, I got a final in two days so I'll be staying up all night watching the whole thing on 1.5x. I really enjoy learning about this stuff as it is so practical. Wish me luck!
ok just watched the whole thing and wow this guy is so talented i watched another video about azure and that one was very helpful as well. very good channel.
I am thoroughly impressed and refreshed with the flow of this tutorial. With years of managing data and creating minor databases (study as I go), I needed to be updated to search for a part-time job after being retired for 2 years. Thank you
I guess he just know how in general programming languages works and then before he makes a tutorial about specific one, he is reading about its syntax and other stuff
The best thing about this guy is that he uses The Office's characters as examples. Beside the fact that he does teach and convey those information and knowledge very well. Thank you very much master!
The amount of knowledge that I've gained from this video is unutterable! I'll be sure to make a substantial as soon as I can. You gave me the power to change my life sir, I cannot express how much you've helped me.
Nobody is gonna comment that he has used The Office characters to explain DBMS. Man! This could not have gone any better. Love the office and loved your Tutorial. Keep making such tutorials!! As a great man once said - " I want people to be afraid of how much they love me." You, my man are on that path!
When I started to learn programming in 2019 the first tutorial I've watched was this guy's C++. Now I'm 2 years into full time software development and I am glad to gain some knowledge from him again.
I randomly landed on this video was just searching what is sql in general and now its been 1hr to the video and i am too hooked ❤ mad respect for this guy, btw i am into HR 😅great video for someone who knows nothing like me🥰
Thank you so much Mike! You are an excellent teacher! I am going to take a data analysis course in college this upcoming semester and I got put in a half semester class and I was very concerned that the pace of the class would be too fast for me. I decided I would try to start learning the material ahead of time so I could keep up and came across your tutorial. You are helping me so much! Much appreciation!
I am just 15 minutes into this course and I really love how you explained each and everything in start and going step by step. no wonder it has 13M views.
Can’t believe what I learn the whole semester in class and now you show everything in 4 hours here. That is amazing. Thank you very much for your tutorial. You are the best teacher !
Did anyone else copy and paste the code from his website and get this error, "Cannot add or update a child row: a foreign key constraint fail" when you ran this line of code, INSERT INTO employee VALUES(101, 'Jan', 'Levinson', '1961-05-11', 'F', 110000, 100, 1);
I built my own website and am now trying to create a database for the cloned version. I had 3 options for learning; tutoring, class or teach myself via TH-cam videos. I am starting with you. I really like how you repeat things to beat it into my head. I really like your style of teaching. I think I’m going to learn a lot from you and I greatly appreciate this video!
5 years after, still valid with respect to Windows installation. PopSQL isn't now as 'open source' as it was, but it stil allows you to follow this course.
I’m in an apprenticeship right now with an IT company who uses SQL and I was assigned an SQL pre-learning material which was useless and didn’t tell me anything. I came to TH-cam for help and I’ve gotta say man, you’ve helped me out a bunch. You have made my life a whole lot easier. Thanks a bunch!
Hey I wanna know that MySQL and SQL is different so the person in this tutorial why is he installing MySQL I think he should install oracle 11g or 19c SQL for SQL tutorials?
Just finished. It took me a whole day and it was worth it. I know c# basics, pyhon basics and js basics. Now i understand how databases work too. I will probably learn ms-sql now and improve my c# skills to hopefully land a job in 3-4-5 months. Il keep yall updated. ps. even tho the video is old, it was totaly worth it. it was probably the best tutorial i have ever seen, and I have seen a lot. Good luck
THE BEST SQL tutorial available for beginners. Everything you need to get started with SQL is clearly explained in this video. Awesome job Mike !! Cannot thank you enough for creating such quality tutorial on SQL. Loved the way you have created Company Database with THE OFFICE reference.
I was going through youtube vides/playlist, udemy course and articles on learning SQL and I landed up on this wonderful video covering concepts in great length. Excellent video and superb effort!
Dude, I just want to give you a huge thanks. Going into this video a week ago I knew nothing about SQL and after working through this video and following along on your website I am now at a point where I know enough to be able to formulate my google searches to get within 98% of what I want and tweak it from there. I'm by no means an SQL master yet but you have given me a great understanding of the subject to build from.
I could imagine this person being able to crunch supercomputer-level databases to start their day. On fire - how easy these courses are for him to teach. I eat it all up - with these - I'm a pro in no time!
@@codewithsheikh2805 I'm learning it right now through this video what other videos u suggest or codes I should learn next for this field I got the table insert all locked this dudes video is so straight to the point.
I'm a programmer from the late 90s. I went for a job that uses databases... but I never really knew what or how they worked. What exactly IS a database?. Well it's been 2 hours (I youtubed this on 2xspeed) and now I'm an expert. I completely know everything, and its thanks to this free tutorial. I have a huge advantage in that I have a coding background... but Now I can do this and make money. I just really need to memorize the commands, and I can do that pretty much in an afternoon. Anyway... thank you.
I was learning from a Udemy course but found it to not be as complete or beginner friendly as I wanted which left me discouraged and a little lost. This course is both of those things, I am learning so much better than I was with just Udemy alone, thank you so much for this video!!!
The error message "You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column" means that you are trying to update a table without specifying a WHERE clause that uses a key column. In your case, the table studant has a primary key column called studant_id. When you update a table with a primary key, you must specify a WHERE clause that uses the primary key column to identify the rows that you want to update. For example, the following query would update the major of the student with the studant_id of 1: UPDATE studant SET major="bio" WHERE studant_id=1;
Leave a like for this guy (for the video) who sat for 4 hrs teaching everything with patience He is truly great, how unfortunate are those 1.6k dislikers
Those dislikes are probably from "slower" parties who needed more than 4 hours to comprehend all the information. All joking aside, unless the person had a fundamental SQL knowledge already, this 4-hour course is likely to be overwhelming for anyone who lacks a decent level of IQ, like myself! Best to break this course into 20-30 minute segments since that is probably the longest anyone new to the topic can properly focus on while also able to learn. It'd still take 4 hours but broken into small installments instead of a single serving.
@@vikasmishra4167 That is exactly what I did and typically do. I don't watch for the sake of watching and think I am actually "getting" it all. Hardly anyone could if they are a new to the subject matter.
This course is good and timeless! You literally discussed a semester's worth of lectures in just 4 hours. I learned a lot here more than in my class. I'm taking this to refresh my knowledge on SQL for a job interview, hope I'll do well.
Wonderful tutorial covering all the basic concepts of SQL. Completed it in 2.5 days.. If you are more focused, probably u can complete it much quicker. He exactly knows where students may get confused with certain topics and he repeats it twice/thrice. Thats the good part. 😊👍👍👍
@@perseusgaming7397 The keyword "describe" only shows the different attribute of the columns of your table such as if a specific column have a default value or not, its data type, unique or not, not null or not, etc. Whereas "select" provide a variety of function, mainly used in showing the "rows" of your table.

I don't agree that you're too wordy, I think the conversational level makes it easy to learn. I have been an educator for decades and for me, your style is perfect, don't listen to that criticism. By the way, thank you for this one and the Python class, good stuff!
I'm on the same boat and, because english is my second language, I appreciate that he reinforces what he's saying because it helps me to better understand the concepts
Hi , how can I get to python class ?? I need the video please

Just want to show my appreciation to the creator of this course. Best 4 hours of my learning slot. Keep up the good work!
i love how he used the office characters as examples making it easier for me to keep track with whats going on given that its my fave show
One day we all are gonna come back and tell this is where it all started ♥️

for sure man

you teach the entire databases course in 4 hours, that is way better and more efficient than my prof who rambles on and i don't get much out of his course for the entire 16 weeks. thanks dude! you're our lifesaver and a silent unsung hero!

oh i can't download popsql :((( may someone help me ?
@@longthanhvu8415 what happen ?
definitely
Nyways to delve deeper?
May be a part 2 or advanced sql????
I would never dislike a video on a man who teaches about sql and databases for 4 hours and its free
Okay so am done with this course after studying it for 4 days. Before giving my review i have to declare interest that am an IT graduate so most of the concepts are not new except for Trigger concept, that was like breaking news to me 😂😂😂😂.
This course covers almost every basic concepts of SQL database. What i like from the instructor was his ability to be so consice and approach a topic in a way that won't be taking too much of your time when you come back for revision especially when an interview is around the corner. But if you want to be more skilled and knowledgeable about SQL then you definitely know this is not all as the title suggests. On scale of 1 to 10, i would rate it 9. It has been good experience and i can't wait for more. God bless all of you trying to get your things right 🙏
after watching this for more than 2 weeks and preparing notes of 95 pages, I'm finally done... there are ppl who finished it in a couple days, don't compare yourself with others, take your time and just make sure you get what your doing.
Could you share your notes?
please share your notes.
I have a interview tomorrow
Hey will you please share your notes
If you could share your notes that'd be a great help for everyone
Realized after watching that this stuff isn't actually hard... it was just never explained well! Thank you Mike!
Not explained in human language
You can say that about most 'difficult' things
Yeah i'm thinking the same
I just completed learning SQL and Python in 1 weekend thanks to this guy 4h courses each. Saturday SQL/Sunday Python. Now am doing HackerRank questions.
Basically wondering if I can learn 2 languages in 1 week for an upcoming technical coding test.
I cannot regret spending my precious time watching and practicing with the tutor. I now describe myself as a data analyst. Thank you.

I have been struggling in my online college course and I am probably not going to give up but I really wish i found this video sooner it is so awesome with great explanations, I got a final in two days so I'll be staying up all night watching the whole thing on 1.5x. I really enjoy learning about this stuff as it is so practical. Wish me luck!
ok just watched the whole thing and wow this guy is so talented i watched another video about azure and that one was very helpful as well. very good channel.
Wish you better luck
I am thoroughly impressed and refreshed with the flow of this tutorial. With years of managing data and creating minor databases (study as I go), I needed to be updated to search for a part-time job after being retired for 2 years. Thank you
This guy is insane, he knows every language
i learned c from him
I guess he just know how in general programming languages works and then before he makes a tutorial about specific one, he is reading about its syntax and other stuff
Maciej Błędkowski once we understand algorithms, we can pick any language and do quite well with google (mainly Stack Overflow)

Does he know Chinese 😂
The best thing about this guy is that he uses The Office's characters as examples. Beside the fact that he does teach and convey those information and knowledge very well. Thank you very much master!

I was looking for this comment. Thank you

The amount of knowledge that I've gained from this video is unutterable! I'll be sure to make a substantial as soon as I can. You gave me the power to change my life sir, I cannot express how much you've helped me.
My greatest appreciation for the teacher in the vid and all of the people behind the scene who helped create this masterpiece!
Nobody is gonna comment that he has used The Office characters to explain DBMS. Man! This could not have gone any better. Love the office and loved your Tutorial. Keep making such tutorials!! As a great man once said - " I want people to be afraid of how much they love me." You, my man are on that path!
My mind is all in tech now.. I though that you refer to MS office and characters as in data types))))) Took me a while :)

Even I didn't notice that untill he started inserting data..and all of sudden I noticed familiar names Micahel, Jim, Kelly ..lol
I liked the part where he played it cool by saying "maybe the work with paper products." Lol
I did lol but not instantly. I had to listen to him say Michael Scott to realize all the databases are based on the office xD
Nearly done learning all the full stack web stuff and I just gotta say...mad respect to this guy. Might not have made it without you.
How long did it take you
hey is there any way to download the pdf of the lesson?
A friend my mine recommended this tutorial. I'd surely be recommending it onwards to anyone who wants to learn SQL.
When I started to learn programming in 2019 the first tutorial I've watched was this guy's C++. Now I'm 2 years into full time software development and I am glad to gain some knowledge from him again.
Could u help me to develop skill

Thanks Mike for designing this course and helping all learn SQL!😊
This dude really just explained the lore of the Office using tables, what a legend
Did anyone else copy and paste the code from his website and get this error, "Cannot add or update a child row: a foreign key constraint fail" when you ran this line of code, INSERT INTO employee VALUES(101, 'Jan', 'Levinson', '1961-05-11', 'F', 110000, 100, 1);
Excellent course. I am teaching myself SQL and I couldn't find a better course. Thank you so much
Do you have an opinion on the Khan Academy course?
How is Cameroon tonight Mr. Ebwele?
I built my own website and am now trying to create a database for the cloned version. I had 3 options for learning; tutoring, class or teach myself via TH-cam videos.
I am starting with you. I really like how you repeat things to beat it into my head. I really like your style of teaching. I think I’m going to learn a lot from you and I greatly appreciate this video!
5 years after, still valid with respect to Windows installation. PopSQL isn't now as 'open source' as it was, but it stil allows you to follow this course.
I’m in an apprenticeship right now with an IT company who uses SQL and I was assigned an SQL pre-learning material which was useless and didn’t tell me anything. I came to TH-cam for help and I’ve gotta say man, you’ve helped me out a bunch. You have made my life a whole lot easier. Thanks a bunch!

I will probably learn ms-sql now and improve my c# skills to hopefully land a job in 3-4-5 months. Il keep yall updated. ps. even tho the video is old, it was totaly worth it. it was probably the best tutorial i have ever seen, and I have seen a lot. Good luck
So what happened now? Do you already have a job?
THE BEST SQL tutorial available for beginners. Everything you need to get started with SQL is clearly explained in this video. Awesome job Mike !! Cannot thank you enough for creating such quality tutorial on SQL. Loved the way you have created Company Database with THE OFFICE reference.

Dude, I just want to give you a huge thanks. Going into this video a week ago I knew nothing about SQL and after working through this video and following along on your website I am now at a point where I know enough to be able to formulate my google searches to get within 98% of what I want and tweak it from there. I'm by no means an SQL master yet but you have given me a great understanding of the subject to build from.
Using the "The Office" scene as an example is pure genius.. it is just perfect for this tutorial!
I could imagine this person being able to crunch supercomputer-level databases to start their day. On fire - how easy these courses are for him to teach. I eat it all up - with these - I'm a pro in no time!
This is an awesome lecture. I didn't know anything about sql till before the day of my interview. But this tutorial helped to ace my interview.

This course couldn't be any better structured and easiest way to get started for SQL. Thank you sir for your time and efforts.
The error message "You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column" means that you are trying to update a table without specifying a WHERE clause that uses a key column.
In your case, the table studant has a primary key column called studant_id. When you update a table with a primary key, you must specify a WHERE clause that uses the primary key column to identify the rows that you want to update.
For example, the following query would update the major of the student with the studant_id of 1:
UPDATE studant
SET major="bio"
WHERE studant_id=1;
Leave a like for this guy (for the video) who sat for 4 hrs teaching everything with patience
He is truly great, how unfortunate are those 1.6k dislikers
Those dislikes are probably from "slower" parties who needed more than 4 hours to comprehend all the information. All joking aside, unless the person had a fundamental SQL knowledge already, this 4-hour course is likely to be overwhelming for anyone who lacks a decent level of IQ, like myself! Best to break this course into 20-30 minute segments since that is probably the longest anyone new to the topic can properly focus on while also able to learn. It'd still take 4 hours but broken into small installments instead of a single serving.
