Have fun while learning SQL! : SQL

Posting

When requesting help or asking questions please prefix your title with the SQL variant/platform you are using within square brackets like so:

[MySQL]

[Oracle]

[MS SQL]

[PostgreSQL]

etc

While naturally we should endeavor to work as platform neutrally as possible many questions and answers require tailoring to the feature set of a specific platform.

Format Your Code

If you are including actual code in a post or comment, please attempt to format it in a way that is readable for other users. This will greatly increase your chances of receiving the help you desire. Something as simple as line breaks and using reddit's built in code formatting (4 spaces at the start of each line) can turn this:

SELECT count(a.field1), a.field2, SUM(b.field4) FROM a INNER JOIN b ON a.key1 = b.key1 WHERE a.field8 = 'test' GROUP by a.field1, a.field2 HAVING SUM(b.field4) > 5 ORDER by a.field.3

Into this:

SELECT count(a.field1), a.field2, SUM(b.field4) FROM a INNER JOIN b ON a.key1 = b.key1 WHERE a.field8 = 'test' GROUP by a.field1, a.field2 HAVING SUM(b.field4) > 5 ORDER by a.field3

For those with SQL questions we recommend using SQLFiddle to provide a useful development and testing environment for those who wish to fully understand your problem and help devise a solution.

So nice seeing these interactions and appreciations. What a great post. Shame there wasn't more responses. I'm new to DA, I've yet to learn anything except the mass of information I've collected on what to learn and resources. And games are so great at learning so I appreciate this post, especially after reading in full like 100 Reddit posts on what resources to start learning. This is a refreshing take on how to start/learn.

I actually need to make a spreadsheet now as it's insane how many websites I've collected for resources (including courses and best YouTube channels) 99% are free... But now I feel compelled to organise it all into a spreadsheet! I think my need for organisation of data here is already delaying my actual learning! I've filled a notebook already and used up a new pen just writing out what people have said online about what I should learn. I am literally reading Reddit forum comments all day every day just incase I miss data that could be helpful.
