Trust me, if you want to start with basics, this is the best tutorial available on the internet, which clears your concepts without wasting much of your time. -- Five years experienced Data Analyst
Thank you. I knew nothing at all about databases or SQL. This video was the best. This guy is very good at introducing a new concept. The best SQL introduction on the internet.
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!

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!
Man, you have to love it, he literally even starts with explaining what computers are for, no detail spared, a caveman could learn from this. It's great teaching. God bless!
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. With you learning is fun and progress can be measured.Keep up the good work. I cannot thank you enough for making learning a pleasant task.
@@cibelless510 Thanks for the encouragement. Successfully completed the SQL tutorial. Finally understood how the join syntax can be written and how it works. -Cheers
It took me 4 days to complete this video, at start i knew nothing about SQL beside its name🤣🤣 and now, I know a lot about SQL, data base, how to write codes, how to use different queries etc. This course puts you on track. a great effort.
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.
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
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!
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!
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 !
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!
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);
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.
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 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.
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
Anyone here coming from an Excel background? I've been using Excel for years in the ways SQL is intended to be used with databases. This video has singlehandedly convinced me to pursue more technical roles!
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’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 RUclips 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?
I went through a few tutorials for beginner SQL and this is by far the best (and last) one I will need to watch. Thank you so much for sharing your knowledge with us...and loved the Office reference too lol
I totally agree with you! But one thing I'm unsure about is that are the "codes" of SQL same for both MySQL and Oracle's ? Or will it be differ at some point ?
I write this to save somebody time. If your like me and you made a table wrong, try to delete it, but cant because it has a foreign key to another table here the solution. SHOW CREATE TABLE table_name; to get the constraint name for that key. Then use ALTER TABLE table_name DROP CONSTRAINT constraint_name. Hope this helps somone cause I spent a lot of time trying to drop a table.
When downloading/installing mySQL shell/command line client, always choose the latest one available, not the version used in the video; because you will get errors otherwise. Hope this saves you some time and effort!
I was about to go with the server version he used, but then when adding the shell I couldn't find the old versions. thankfully came across this comment before proceeding with the install.
This guy is a legend at breaking down complex ideas into their simplest forms and understands how to pace the concepts and the importance of repetition and/or redundancy when learning something new; a great teacher
This is one of the best learning videos I've come across so far. I have been watching all the videos on this course on this channel for some weeks. I loved the course all through. I always looked forward to continue watching and practicing. Mike made a complicated language really simple and easy to learn. Only a great and amazing teacher can do that. Thank you so much, Mike.
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!
Of course, a lot of comments have heaped praised upon this video and it completely deserves it. It has condensed the database course I took in university into a 4 hour course that is really easy to follow along. Mike makes it quite engaging with his style of delivery. As a couple of others have also pointed out, Mike used the data from the Office to populate the different tables in the database, which was a nice touch. Thanks a lot for this course, I'm glad I found it and could use it to refresh my knowledge of the concepts.
@@mukhammed_kaldybai the of course at the start of the first sentence was likely misleading, thanks for pointing it out. But it also seems as though you've gotten used to reading negative comments on RUclips. I know where you're coming from 😂
I've just finished this course. I wanted to revise what I've learned in a previous semester in my campus because I have a module on 'Advanced Data Management' coming up next semester. I learned many SQL codes which I didn't know before and learned how to convert a set of requirements into a database schema step by step. Thanks so much Mike for creating this valuable content!
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.
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.
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
Bro, I took upper-level database classes. He's covered more in 40 minutes than we covered in 2 weeks. College IS a rip-off, but I didn't start interviewing for 6-figure positions until I could check off that "has a 4 year degree" box. It sucks. Only 40k in debt, thankfully.
I totally love it! I have had no programming classes or any other close-to-SQL-excersices and I was able to understand everything. Thanks for this material!
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.
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 🙏
Thank you very much for this. I had to learn SQL in a short time using MySQL and you have saved my life! I searched for something like this for a long time and there is NOTHING out there like you; easy to understand for beginners, clear and proper examples and actual coding instead of adding another program to just click around (which most importantly is what I was required to do for my assignment). Keep up the phenomenal work! I recommended you to other students like me, who were struggling with no proper help from learned lecturers.
@@saumyamaheshwari2317 ya, I tried contacting the developers of popsql but they didn't respond to it. so I am using "mysql workbench" it is as effective as popsql u can try.
Just a small correction. The employee table in the picture has column 'birth_date' whereas if you copy the SQL code from the given PDF, the column name is 'birth_day'. So while you are running some of the example queries, you might bump into an error. Just change the column name and the query will work! 👍
@@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.
This is my first day of learning SQL and I can confidently say you make it seems easy to me. Still on 40 minutes in and I’m understanding the concept. I’m trying to teach myself. Thank you man.
Hi my query from (wildcards) employee table ”SELECT * FROM employee where birth_date Like’%____ -10%’; did not retrive data from the table although status :Success and bring me empty table😔i have data in employee table.Can someone help me please
@@Piar2004 LIKE '____-10%' u should be using this , '_' this replaces a character where as % is for any number of characters ,, u used both of them along (’%__ -10%’) .
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.
FOR THE REAL BEGINNERS: Two things to you will want to check if you install beyond what is used in the tutorial is to have Python and Microsoft Visual Studio. My circumstance will also require Python and some other things. Make sure that you have the space and power for them. If you need to get an external hard drive to store the programs, there is a hack and work around for running programs from an external hard drive. Secondly, the possible additional software needed will require extra TIME that you will want to factor in for this tutorial. As seen below, this is a quality video. But, I had to pause for a good while to get just these 2 requirements installed before I could complete the MySQL installation. HTH to all the self-taught people pulling themselves up.
Thanks so much Mike! This was my introduction to SQL and what a fantastic one at that. The explanations were lucid and not one word felt wasted. Many thanks!

Trust me, if you want to start with basics, this is the best tutorial available on the internet, which clears your concepts without wasting much of your time.

What is another resource if I finished this video?
Thank you. I knew nothing at all about databases or SQL. This video was the best. This guy is very good at introducing a new concept. The best SQL introduction on the internet.
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

I was just gonna comment this but you already did it
The fact that you ended with ER diagrams that was exactly the tables created during the tutorial is legendary. Best SQL course I have followed.
4h20m without ads! Humanity still exists.

and he explained much better than my teachers, it's like this lad is sent by God to help with the exams
What’s wrong with the ads can’t you see them they will at least give some money to them. He randomly didn’t put it
I honestly don't think by putting Ads he will be hurting anyone. He can put ads in the end . He put little effort here , so he deserve little.

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. With you learning is fun and progress can be measured.Keep up the good work. I cannot thank you enough for making learning a pleasant task.

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?
best lecture on dbms. This guy has whole computer database hidden in him.Lots of love❤❤
I went through a few tutorials for beginner SQL and this is by far the best (and last) one I will need to watch. Thank you so much for sharing your knowledge with us...and loved the Office reference too lol
I totally agree with you! But one thing I'm unsure about is that are the "codes" of SQL same for both MySQL and Oracle's ? Or will it be differ at some point ?
@@rosjja differ a little
I write this to save somebody time. If your like me and you made a table wrong, try to delete it, but cant because it has a foreign key to another table here the solution. SHOW CREATE TABLE table_name; to get the constraint name for that key. Then use ALTER TABLE table_name DROP CONSTRAINT constraint_name. Hope this helps somone cause I spent a lot of time trying to drop a table.
When downloading/installing mySQL shell/command line client, always choose the latest one available, not the version used in the video; because you will get errors otherwise.
Hope this saves you some time and effort!
I was about to go with the server version he used, but then when adding the shell I couldn't find the old versions. thankfully came across this comment before proceeding with the install.
thanks

Good job for pointing it out, thank you
maybe that's the reason why i'm getting this "permission denied for schema public" error.. will update mine.. followed his version..

The way you demystify things is truly amazing. You're a great teacher
This guy is a legend at breaking down complex ideas into their simplest forms and understands how to pace the concepts and the importance of repetition and/or redundancy when learning something new; a great teacher
This is one of the best learning videos I've come across so far. I have been watching all the videos on this course on this channel for some weeks. I loved the course all through. I always looked forward to continue watching and practicing. Mike made a complicated language really simple and easy to learn. Only a great and amazing teacher can do that. Thank you so much, Mike.
Agreed!
You have taught me more programming than my college ever did in those 4 yrs !!
Dude seriously your tutorials are GOLD!Especially for people who are just lost thinking where to start or learn programming from!!THANK YOU!!
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!
Of course, a lot of comments have heaped praised upon this video and it completely deserves it. It has condensed the database course I took in university into a 4 hour course that is really easy to follow along. Mike makes it quite engaging with his style of delivery. As a couple of others have also pointed out, Mike used the data from the Office to populate the different tables in the database, which was a nice touch. Thanks a lot for this course, I'm glad I found it and could use it to refresh my knowledge of the concepts.

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 4 hour 'amateur' tutorial taught me more, and with clarity, what a 36 hour course couldn't... Lower and mid tier college is such a rip-off.
Bro, I took upper-level database classes. He's covered more in 40 minutes than we covered in 2 weeks. College IS a rip-off, but I didn't start interviewing for 6-figure positions until I could check off that "has a 4 year degree" box. It sucks. Only 40k in debt, thankfully.

Neil Heckman yeah nothing is really free ever. Someone is paying for it. I should have said this is way way way cheaper then going to college

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.

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 🙏
Using data from "The Office" made the course waaaaaay more fun, thank you :p
Thank you very much for this. I had to learn SQL in a short time using MySQL and you have saved my life! I searched for something like this for a long time and there is NOTHING out there like you; easy to understand for beginners, clear and proper examples and actual coding instead of adding another program to just click around (which most importantly is what I was required to do for my assignment). Keep up the phenomenal work! I recommended you to other students like me, who were struggling with no proper help from learned lecturers.

You're more informative and effective than any of my college professors who taught this. Thanks for the free knowledge
FOR THE REAL BEGINNERS: Two things to you will want to check if you install beyond what is used in the tutorial is to have Python and Microsoft Visual Studio. My circumstance will also require Python and some other things. Make sure that you have the space and power for them. If you need to get an external hard drive to store the programs, there is a hack and work around for running programs from an external hard drive. Secondly, the possible additional software needed will require extra TIME that you will want to factor in for this tutorial. As seen below, this is a quality video. But, I had to pause for a good while to get just these 2 requirements installed before I could complete the MySQL installation. HTH to all the self-taught people pulling themselves up.
Thanks so much Mike! This was my introduction to SQL and what a fantastic one at that. The explanations were lucid and not one word felt wasted. Many thanks!
