SQL Tutorial for Beginners
Вставка
- Опубліковано 6 чер 2024
- In this step-by-step tutorial, learn how you can write your own SQL queries. You don't need any prior knowledge and we're going to use all free tools. By the end of this video, you'll know how to retrieve data from databases. At the end, I'll show you a neat trick to write some of the most complex queries with very little effort.
SQL stands for structured query language. It's a language that you can use to talk to your database. You can also use it to retrieve, filter, sort, combine, add, update, and delete data in a database. It's basically a language you can use to interact with the database. The great thing is that anyone can learn how to write SQL queries. You definitely don't need a degree in computer science. And once you know it, you'll have another superpower that you can use at work.

Hi Kevin. I'm a retired software architect with lots of experience of SQL, and only watched the video to see what you were presenting to newbies. I wanted to let you know that it's an excellent introduction to something many might be hesitant about. Great job!
Thanks for the note, Simon!
He's right, as a newbie, I'm quite hesitant! Lol thanks for the video Kevin
Hi Simon Dobson, is it Ok to pick your brain on something related to Software development?
software architect?? pfffft. Im a software god/oracle PHD.
@@Adam_Bosscoe hmmm.
This is 2 of my university courses summarized in a 45 minute video. So impressive and so helpful! Thanks, Kevin
University?😭 im watching this for my grade 9 term two end of term assesment
@@heynotizzy7493 good for you, man! This isn't something that was covered by my school back then, so you're getting really ahead of us oldies lmao
@@shayanzaidi2836 i wish i was at the level of you oldies because i currently have a C in computer science
@@shayanzaidi2836 oh wow - I was just watching to gain a skill for work purposes - now feels like a daunting task haha.
Currently unemployed but have experienced in HR and HRIS systems - hopefully learning this will help me land a new HRIS job!
@@heynotizzy7493 how did it go???
You have a gift for making complex subjects look very simple. As a software specialist, I’m sure this video took quite a few hours to put together. You started with baby steps but by the end, there was some quite advanced material being covered and I learned a few things that I didn’t previously know. Something for everybody - thank-you!
Indeed, I learned so much from you Kevin. Thank you so much.
16:08 If you're getting an error like I did, do the following:
1) Right click KCC and select properties
2) Select Files
3) On the row of "Owner:" select the "..." at the end
4) Browse -> check [sa] -> OK
Now you should be good!
Thank you, This really helped!
Thanks bro. saved me a headache.
THANK YOU SM
Hero!
comment saved me, thanks
Kelvin, I never thought one day I'd ever think about SQL. I always knew it's for the IT guys!!! Everyone can learn it? I can only Believe this because I trust you!!! You present complex matters into a plan language. Thanks
I watched this 4 times already and I am going to watch at least 10 more to memorize all the queries listed in this video! Thanks so much Kevin for the awesome video and can't wait to learn more about SQL in your next videos!
Out of all the tutorials available, this one is the most straightforward and user-friendly. Kevin, I appreciate you for generously sharing your expertise.
I’m a stay at home mom looking to learn some new skills and enter the work place. It’s been incredibly daunting and all the other SQL lessons I’ve taken skim over important information and don’t describe things clearly. This was SOOO helpful!!! Thank you so much!
how was it helpful can you explain? we work in Excel files not bak formats. The link he provided for file is not even working. What did you accomplish from this video Exactly?
yeah it did work. did you download the batch file or the flat file? Also did you store it in the correct file path where the server looks?@@sunnysingh347
That’s awesome that this video helped ! Did you find a coding job using SQL?
hey are u currently working a position related to SQL? how has the job been?
OMG, from my work place I thought SQL looked too difficult so I abandoned trying to use it to find certain data. I had no idea that there was a query wizard that is actually easier to use than MS Access. This changes everything. THANK YOU KEVIN ! And yes, SQL training would be great.
This tutoral is straight to the point. Everything was explained perfectly - not too short which becomes confusing and not too long which becomes boring - just perfect! Thanks!
For those who are following along and could not open the database diagram: Right-click "KCC" in the Object Explorer, then select "Properties". Under "Select a page", select "Files". Enter "sa" in the owner field and click "OK". The problem should be solved!
I made a typo in my comment a year ago, where "sa" was "as" due to autocorrect. However, that comment has since helped a lot of you with opening the diagram. UA-cam wouldn't let me edit my comment cause it returned error. Kevin, if you see this feel free to re-pin this comment. Thanks!
Thank you, sir! that fixed it.
How do i double like this? Thank you so much!
Thank you!
It works if I type "sa", but if I type "as" it says that it cannot find the princial "as", because it does not exist or you do not have permission, Error 15151
this comment should definitely be pinned! thank u so much, I really appreciate your help and clear instructions
I literally became comfortable with knowing how I will be using SQL & I’ve only watched 30mins of it. Clear & precise instructions & explanations of shortcuts! Highly recommend this video to any beginner!
Kevin, I LOVE writing SQL. I did it for 17 years and now I'm making videos using MS Access. I wouldn't do a beginner's video using SQL Server but you nailed it. Great job, cheers!
Hi, I need help on my bet project on excel
Kevin, please, please, please make more SQL content? I work in the database but there is so much more to learn. I just love your approach when it comes to learning new skills and your videos are so easy to follow. My goal is to become certified by the end of this year. Thank you so much for this!
yes kevin plz come up with complete series
Hello Chantel, Please don't be offended by my question, please i can one get entry job as DBA? I will appreciate you feedback.
Did you become certified after all?
Hey did you commit or nah @chantelruss6063
I’m wondering too. Are certified yet ? In SQL ? Or database? Or Data analytics? And is it enough?
Learning this for a job interview this week, thank you! It's a SQL heavy job, but I didn't put anthing SQL related on my resume and they still called me back so knowing the basics to mention in the interview will be a big help!
Kevin, THANK YOU!!! I have been trying for the last couple of months to learn SQL. I understand putting in the steps, but I need the "why" . Tonight you made it click. You have no idea how thrilled I am. Thank you so so much for your fantastic explanation. I wIsh I were paying you for a course instead of what I'm taking. You're very patient and explain it all so it makes sense.
This explained the join process easier in 5 minutes than 2 full days of class in college.
Nicely done.
Thanks Kevin, your attention to detail and delivery in all your videos is first class, very professional and as always so informative and easy to follow, your efforts make all our lives so much easier.
I'm an old, mostly self taught DBA/Database-Developer that started working with SQL Server in 1998. I'm also a former Navy Instructor that wrote and taught a 200 hour course on microprocessors and how to program them way back in 1977 and have been teaching a whole lot of different things, including a lot of things about SQL Server and T-SQL. With that, I'll also say that I'm not easily impressed. And, with that being said....
You probably hear this all the time but now I have to say it. This is an absolutely brilliant introduction to SQL and SSMS and the order of revelation is perfect. Having put together presentations on the subject, I also have a deep understanding of, even with the best of tools, how long it takes to put to craft, crop, and publish a video of such incredible content.
Very, VERY well done, good Sir.
Kevin ,
It was a great session for a very beginners like me who is zero in coding .
Wherever I stuck somewhere you helped me a lot eg. I stuck in macros - seen many videos which i couldn't able to understand but your explanation is extraordinary. As like that SQL learnt new many constraints and shortcuts too
Thank you so much 🙏
I've watched a lot SQL introduction for beginners and no doubt this is the best one, hopefully we can get some more videos on SQL, thanks Kevin!
As a new student to SQL you've made things way too easy bro 😊 best training ❤
I'm just starting a Data Science bootcamp in the UK , London and wanted to get some basic understanding of SQL as I will be studying it. This video is very simple whilst a good amount of knowledge and benefits in it. Genuinely appreciate it. Thanks
SQL is used extensively in all business, even if you want to build WordPress sites SQL is behind all wordpress software and controls all of the content in your sites, being able to write queries is truly a 'superpower' and this video is among the better ones to introduce the rudiments
This is wonderful, I learned more in this video then I have in a week of trying to learn from other sources. I would love more SQL videos!
EXCELLENT EXCELLENT EXCELLENT tutorial with all necessary details needed for a beginner like me...I'm taking a SQL course on Udemy but this is easier to understand. THANK YOU SO MUCH!
Coursera's is so murky I filed a BUG REPORT.
I am just starting to learn SQL and I have to say - that is the best course that I’ve ever seen covering what most view as a complex thing to learn!!! You gained a new follower!!
Oh man, couldn't help but subscribe, I came here looking for one solution but walked away with multiple solutions. Thank you so much!
You read my mind! I was asking a friend if he can help me learn SQL just today! Thanks Kevin.
Kevin you removed the obstacle of learning code with this amazing tutotial. SQL is no longer a mystery for me. Thanks for coaching us.
I have to say, I'm loving the pace of this video. Ive bewn putting off leaening database for so long that, I decided to motivate myself by putting on a long tutorial video and just passively absorbing, and I am surprised by how much I'm able to follow along without having to pause and tinker with things myself yet.
I'm nearly a graduated computer science major who missed taking Database and ran out of credits. So i guess I'm on my own for learning database. So here I am.
Kevin I just stoped watching the vid in the middle of the vid just to write this , you are awesome Kevin you are unique you explain in detail and at the same time not boring details , your tone your steps everything is awesome please keep making those vids about sql don't keep up waiting for long please
Kevin, you're the best! I've been watching your videos from powerBI, Python, teams etc. I'm currently taking a bootcamp and have been struggling in writing the JOINs. I understood the concept but struggled with the placements. Thank you! I would love to see you do videos on java as that is my next stack.
Amazing! Thank you for Crystal clear instructions and explanations on SQL tutorial. I plan on downloading the two software you mentioned and start writing SQL tomorrow. Thank you Kevin!
I would love to see this become a series. I stumbled across your channel after being assigned a SQL project at work and it has been well over 10 years since I last used this program for data analysis. Thank you for such a great introductory video.
Thank you, Kevin. I love watching your tutorials. You are so detailed and attention grabbing fro someone like me with a short attention span and I appreciate it so much.
To those who can not locate the KCC file when trying to add it in the Database. Copy paste or Move the File to the Backup folder which is located in Microsoft SQL server ---> MSSQL16.MSSQLSERVER ---> MSSQL. These files are located where you originally downloaded the whole software probably in Local disk C ---> Program Files. This will then automatically show the KCC file when you try to select it to add it in the Database like Kevin told in the video. Hope this helps.
Thanks! This worked perfectly for me :D
Thank you ! This helped :)
Thanks!
thank you so much!! :D
THANK YOU!
I am barely in and love your video already-1) assuming no knowledge 2) using free tools so continuous learning is an option. Many thanks!
Hello Kevin, there is no waste on your video. I am a little bit new to SQL Server, but your video just open up wide my mind. I appreciate for you making this video.
Hi Kevin, Thank you for your time. This video is very informative and clearly explained compared to most of the other videos out there. keep up the good work and don't change your format this video is very clear and doesn't just speed by skipping over basic concepts that can help bring the audience up to speed while they obtain a solid foundation. Thanks again Kevin You Rock!!!
Awesome Kevin! For me this tutorial is "SQL" (Super Quality Learning)! Thank you so much! 😊👍
Normally, I dont comment on tutorials, but yours is an exception. Was a little scared learning and working with MS SQL, but your tutorial helped me a lot. Subscribed.
My database class has turned into a DIY class so I'm really grateful for videos like this!
Based on my limited knowledge in SQL (I only learned it before so I could creates simple queries on our Access database), I'd say the Query Editors are quite similar but MS SQL is more complex and powerful. I'm looking forward to your tutorials and hopefully you'll cover more functions or at least the most commonly used ones. Thank you, Kevin! ;)
Thank you so much for this the Way you write it down and explain it is so amazing and easy
Man there is soooo much work that comes into these videos. This guy is awesome!
I like how the fact that you're practical and down to Earth really gives meaning to the subject alltogether
I wanted to learn how to code in SQL for job opportunities because that's what 90% of applications require for what I am planning to go into. This video is unbelievably helpful, I just learned how to do decently complex tasks in 45 minutes with (albeit some struggle with the .bak file but otherwise) no experience. Thank you for what you do!
Im in the same boat. Any idea how you will tell them you will write on your resume that you know SQL? As we won't have a certificate or anything
Hi Kevin, I don't have any background in IT but, your videos are really helpful for beginners like me to understand the basic concept of SQL. Once again thank you so much for this awesome video. I am waiting for more videos based on SQL please and thank you.
Thanks for such a superb, easy to understand video. I'm new to SQL and never knew it was so beginner-friendly; your content was most helpful. Just 2 points I'd like to add for others who may be interested in checking this out too. 1. If you have trouble finding the KCC.bak file using Database restore, Goto SQL config manager and change the "Log On as" setting of the SQL Server to "Local System". 2. For some reason my Database Diagrams folder would not expand, couldn't figure out a fix, however the query design editor will show the tables & primary keys anyways. Thanks again!
you answered my query for not able to KCC file! Thanks @sajikr3438
Thank you for this! Saved me tons of time researching why I couldn't find the .bak file.
Me neither, I cant expand database diagrams folder
2. For some reason my Database Diagrams folder would not expand, couldn't figure out a fix, however the query design editor will show the tables & primary keys anyways
I did this and the KCC.bak file still doesn't show up in the directory.
Best comment so far, This is exactly what I needed to do. Thank you so much!
i was trying to learn the sql from a platform but i didn't understand them what were they talking, because i'm completely new to sql, so i quit that online program and searched on youtube and found your channel which was already subscribed by me for some other purpose, and i lovvvvvvvvvveeee this i get each and every point you teach. thank you so much Kevin
I have worked in technology for a while now but never got around to learning SQL. This is awesome, thank you!!
This is an amazing introductory training to SQL!!!!
Well done sir. Clear, carefully explained, insightful, and a wonderful introduction. I constantly refer students as an example while teaching logic. Your handle on and way of explaining the basics of sentential is commendable to say the least. Thank you.
Been out of work for the past year looking after my Son and this video gave me a great refresher on everything having not used SQL in that time. I feel much better going back to work now. Unlike C# I find my SQL knowledge gets worse of I don't use it because it's so different to use.
Bro you are a godsend. I am getting back into sql after taking 2 years off and this was perfect to jog my memory. I appreciate your effort man
Please do more SQL content!? Databases, everything. Something I'm trying to learn along with web development this year.
I totally agree with you! I love working with databases.
Indeed. More of this please! :) Appreciated all your trips and tricks on all of your vids.
Yes, I second this comment. Would love to see more SQL, and databases content too.
@@brand1974 I just posted a video on how I created a stored procedure on my channel. Check it out.
Yes, please! More SQL content :)
On a job hunt as a result of the massive tech layoffs sweeping the country right now and this just made me so much more comfortable applying to jobs that demand SQL knowledge.
Totally agree. I just had an interview where the main function for the IS role was SQL and well.. This helps to feel comfortable if they call me for a second interview.
太好了，45分钟，只看一遍，做点笔记就ok了。谢谢谢谢，开门见山，没有废话👍
Thanks Kevin for this great video. As I was looking around to get an into to SQL, I immediately thought of your video, knowing that it was going to be easy to follow and logical - as usual you did not disappoint!
I definitely appreciate this and would like to see more about SQL!
Thank you so much Kevin.
Once again top of the line.
If I could afford you I would hire you to lecture my students.
I will suffice with using your tutorials to enhance my own courses.
Now I only need a few about Sharepoint Spaces.
Hi Kevin, I'm a beginner in the field of data analysis. I love watching your videos because you teaching method is interesting and very easy to follow. More power to your elbow.💪💪💪
Hello Kevin - I just wanted to learn SQL and your presentation is so easy to understand SQL. Your detailed instructions took away my fear of learning SQL, I'm hooked! THANK YOU!
Wow, so fantastic SQL Server course! I have been looking forward on this from you for a long time! You are a super star!
I loved the way you explained it. Very intensive. Loved and Subscribed. ❤️🤗
Wow. I like how you have simplified SQL and made it more palatable to understand. Thanks
Amazing. You made it very understandable and I used it to complete my SQL project for CIS/SW engineering class.
Thank you!
Thank you so much Kevin for this amazing video. This is like you read my mind . Waiting for more videos . You make everything looks so so simple and interesting.
Thank you so much for creating these videos for us!
"Free tools" are my favourite kind of tools. Thank you for this, Kevin.
Kevin .. first of all you are a master of simplicity!!! man, you are a lifesaver!!! Before watching your video I had zaro % knowledge of WTH is SQL. But now. I am very confident that I can learn this dam thing. especially the design query by editor it solves the whole thing!!! I will watch this vid again and again to master it but wanted to THANK YOU from the bottom of my heart
Appreciate the quality of your presentation and material, always no-nonsense, clear and easy to follow.
This one was a great primer for databases plus SQL queries... Squeezed a lot into the time.
MS products seem great for pros but there are others out there especially FOSS, for people wanting to use .db on their pc.
Amazing please kindly upload videos related to Windows Server Administration and troubleshooting, Office 365 Administration and troubleshooting as it will be very very helpful
Nice Job Kevin. I've been developing reports, queries, & apps on MS-SQL for more than 20 years. Next up vote for PowerBI.
This is truly an amazing tutorial for someone starting SQL.
Hi Kevin, I have been having trouble importing data from excel or any other source. It keeps telling me operation could not be completed
Hello, I know this might be a silly question, but I save your KCC data in my desktop but can't seem to find it when I click on restore databases. Is it because it is not stored in the backup file? Do you have a quick video on that? Thank you very much!
I'm having the same problem. Did you find the way out?
I really appreciate how you break down and explain what everything is. Thank you!
just got a new job and I told people i knew sql, you are a savior
For those getting backend database error when trying to load the database diagram, download the preview version for SSMS 19 and not the latest release of 18.12. If you already installed 18.12, uninstall it before installing the preview version 19. I guess the latest version of SQL is incompatible with the latest release of SSMS? Seems like a major oversight.
Thank you. This worked for me. Had already fixed the first issue of not being able to expand Database Diagrams then ran into this lol.
Kevin this is me Neil! I am trying this out but am facing a problem. I downloaded your database and can view the tables but when I expand the database diagram menu it shows an error.
It says: Cannot execute as the database principal because the principal "dbo" does not exist, this type of principal cannot be impersonated, or you do not have permission.
Please help Sir.... your tutorial is great but I cannot continue :(
To solve, I went in to Properties of the database - Then under "Select Page" click on "Files". Under database name the "Owner" was blank. Click on the 3 ellipse to open the "Database Owner" window. Click on browse next to "Enter the object names to select (examples)". Scroll down to where the object is [sa] and click "ok". Click "ok" on the next window and finally click on "ok". as this will have the owner in the once blank box. This worked for me, I hope it will work for you as well.
@@dk81535TA Thank you so much! I had the same problem and it worked for me! :)
@@dk81535TA Thank You that worked for me as well :)
@@dk81535TA Thank you. This worked for me.
Thanks for the informative tutorial teacher Kevin! A little bit struggle at the first part until after 4:05; then things got clear to me so much. This gave me a better picture on my major, and also subjects we required to learn in college (such as statistics, econometrics - which also shares some terms similar like in SQL language). This introduction to SQL beginner was so good, that when I came back to W3S to continue the lesson I managed to understand different commands and usage of different functions. The diagrams and keys were notable too, it helped me figure out the primary keys connecting to different columns. Anw, thanks for the informative guide, proud to be your new subscriber!
Hey man, I’m learning about SQL and database concepts for the first time and I gotta say, this video was very easy to follow. I tend to get distracted when watching tutorials, but the way you made this video made it easy for me to focus! Thank you!
Best video I have ever seen on SQL. Thank you for sharing your knowledge and making life easier for the world 😃
Hi Kevin. I'm having an issue following along when trying to recover the sample database. In your video, the sample database file is already there ready to add. However, when I try to find my sample file I cannot find the file using any file path or manually trying to retrieve it.
I'm having the same issue; did you ever recover the file?
@@lukeloeffler8032 no, I was lucky enough to take a SQL class at work.
all other SQL - window functions, etc.
Dude. Your videos are an absolutely incredible resource. You have supercharged my career jumping into a brand new role. Thank you.
I literally have an exam tomorrow about this and I know nothing. This video helped me SO much, its so well explained and easy to understand. Thank you Kevin!

when I was at university I totally blew up learning sql, and my teacher (very wise woman) told me - "you're barely passed your test but YOU HAVE TO know sql anyways". Back then I answered that I don't need it because of specifics of my work, but my ignorance finally kicked me in the butt 15 years later. And now I've finally nailed it. Thanks so much for this video!
I am getting back to University after 10 years came to refresh what I had learned. Very good recap. Thank you for the great job
I'm about to get into an interview for a job that requires basic SQL knowledge, and this was really helpful
Fantastic! Everything was so easy to comprehend. I thought sql was so difficult until I watched this video. Thanks.
Hi Kevin, I wanted to thank you so much for this fantastic video. You explain so well. I have just started a QA Course and know nothing about it , but was told we'll be learning SQL , so popped in to see what it's all about. WOW , you make it look so easy, hope it will be ... carry on doing these great videos as you are helping so many. THANK YOU
So far, best introduction to SQL I've come across. Looking forward to more content.😊
This is the best video for any beginer hoping to learn SQL.
One of the most informative tutorials on Sql that I have seen in a long time thanks and keep on making more.
In your last segment, Query Designer, reminded me a lot about MS Access. It alone, for me, makes your outstanding tutorial much easier to wrap my head around. Thank you.
This has helped me so much for my college database systems class, and I always appreciate a video with good captions
