There are many free resources online for learning SQL. Here are some of them:
Khan Academy has a SQL course:
https://www.khanacademy.org/computing/computer-programming/sql https://www.khanacademy.org/computing/computer-programming/s...
The one in the first link below is interesting in that it then sets you up for the SQL Murder Mystery in the second link:
https://mystery.knightlab.com/walkthrough.html https://mystery.knightlab.com/walkthrough.html
https://mystery.knightlab.com/ https://mystery.knightlab.com/
The "walkthrough" link above mentions that if you want to learn SQL more deeply to try selectstarsql.com, which looks good:
https://selectstarsql.com/ https://selectstarsql.com/
This looks interesting too:
https://sqlzoo.net/wiki/SQL_Tutorial https://sqlzoo.net/wiki/SQL_Tutorial
Most of the above have databases available for you to immediately try out what you're learning, which should be helpful (sqlzoo.net also seems to have some more advanced topics covered too).
There are also a bunch of (multi-hour) courses on YouTube:
https://www.google.com/search?q=site%3Ayoutube.com+sql+course https://www.google.com/search?q=site%3Ayoutube.com+sql+cours...
If you go the video route, there are sites like SqlFiddle.com and freedatabase.com, etc. that let you set up databases so you can practice what you learn from the videos without having to install anything (though you can do that too, of course):
https://www.google.com/search?online+sql+database https://www.google.com/search?online+sql+database
I hope you find at least some of the above to be useful. Good luck with it.
- zbhoy 4y agoThis is amazing! Thank you so much
- qohen 4y agoYou're welcome. :-) Also, there are some (legitimately) free SQL books that might be worth a look: https://www.linuxlinks.com/excellent-free-books-learn-sql/ https://www.linuxlinks.com/excellent-free-books-learn-sql/ Then there's this freebie, which is interesting in that it's compiled from StackOverflow, whose content is licensed under Creative-Commons -- GoalKicker has a bunch of these on various tech topics. Anyway, the SQL one might have some useful tips/tricks: https://books.goalkicker.com/SQLBook/SQLNotesForProfessionals.pdf https://books.goalkicker.com/SQLBook/SQLNotesForProfessional... (It has gotten good ratings and reviews: https://www.goodreads.com/book/show/40730648-sql-notes-for-professionals#other_reviews https://www.goodreads.com/book/show/40730648-sql-notes-for-p... ) They also have such books on specific databases: MySQL, Postgres, SQLServer and Oracle -- see all their books on their main page: https://books.goalkicker.com https://books.goalkicker.com And, once you learn SQL, you might want to check out webpages (and YouTube videos) of SQL tips/tricks to pick up useful tidbits: https://www.google.com/search?q=sql+tips https://www.google.com/search?q=sql+tips https://www.google.com/search?q=sql+tricks https://www.google.com/search?q=sql+tricks
