SQL Index |¦| Indexes in SQL |¦| Database Index

It's official! The Socratica Python Kickstarter was a success! Thank you to all of our supporters. Because of you, many more Python videos coming soon!! 💜🦉

fantastic video. thank you for sharing.

WOW My jaw is on the floor at how amazing this video is! Quality, tone and speed of voice is on point. Explanations are well thought out and provide all necessary context to comprehend. Video/Audio editing is perfect with just enough to keep it interesting and remove distractions.

Excellent video.

the best explain of index ever...

thank you for this nice work!

perfect

🎯 Key Takeaways for quick navigation:

Indexes in SQL are essential for speeding up queries by allowing the database to quickly locate data based on specified columns.
Without indexes, queries can be slow when dealing with large datasets, as the database must scan all rows to find matches.
Indexes are created using the "CREATE INDEX" command, specifying the table and columns to be indexed.
Indexes significantly improve query performance for the columns they are built on.
Queries that don't involve the indexed columns won't benefit from the index and may still be slow.
The database optimizer selects the most efficient query plan, considering available indexes.
Multi-column indexes can be created, and the order of columns in the index matters for query optimization.
Indexes come at a cost in terms of storage and maintenance, so they should be used judiciously.
Regularly updating and maintaining indexes is important to ensure their effectiveness in improving query performance.

amazing.... she can teach me SQL all the time any time every single time.

I must say, Excellent content! Brilliantly explained. Wel done!

👏🏽👏👏

Straight to the point unlike other tutorials. I only needed the concept really..

i really love your videos !!

Wow, that was quite an impressive explanation. Thanks!

I really enjoyed your video.thank you!!

No words, Amazing Video <3

Thank you, good explanation

This is one of the best computer science videos I've seen in my career (I'm final year 2 at uni) and whole life also, you rock!

I don't think any educational material has been as entertaining as this playlist I just watched... It's mind blowing!... Totally the best investment of my time!

Would be an index beneficial on a column with unique values?

man i love dr evil

Great video! One tip: Adding indexes to a table will speed up select commands but will also slow down other commands like insert/update/delete because the SQL server has to reconsider the indexes if any kind of modifying transaction occurs in the future.

Nice video, great subtitles.

how does the create index function behave for a table that is constantly being updated? are new rows automatically indexed, or do we need to run it each time?

That U for the amazing content about SQL, for now on I know where to find the answers.

its awsome

😄😄😄

i cant believe how you didnt show a representation on how an index looks like, besides that a wounderful video

love you so much mam,thats perfect lecture

That laugh at the end was EPIC! I love your work :)

Wow, this is like watching a thriller movie🍿.

thanks for awsome work, very easy to understand in real examples

Laugh :✔️
Explanation:✔️
New favorite data science channel:✔️

This video made me excited to learn more SQL 🥰

This is quite a goofy video but at the end I learned everything I needed unlike from watching other videos on this topic by different content creators. Thank you for such a great video.

First, I really think these videos do a great job of teaching their lessons. Second, I really appreciate your commitment to the bit.

Awesome channel👍👍 new sub indeed!

100 Billion subscribers, that seems like quite a stretch

amazing.....

she nailed the evil laugh

!!! WARNING !!! The primary key is always automatically indexed and unique. So, beware not to create redundant indexes.

first video on indexes i clicked , amazing!!!!!!!!

I dream about the lessons of neural networks (perceptrons and so on) from Socratica

Super Excellent! Well Done!!! Thanks (y)

LOL This is informative, and pretty entertaining! I like your vids.
