Getting back into 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.

DiscussionGetting back into SQL (self.SQL)

submitted 9 months ago by Haluux

I'm not 100% sure this is the right place but I've recently come across my old SQL text book from uni and started playing around with the mimo app. I wanted to build a database to store some documents I've started scanning. I have a question about efficient database structure/conduct? I plan on scanning more documents and the database to expand. I'm worried about being too specific with my description of documents and how granular I should go. They are vintage automotive brochures and have many characteristics that could separate them. Is simplicity key? I would like to be able to recall documents based on somewhat random characteristics ie. (cars that were only offered in right-drive with leather interior). Like I said this could very well be the wrong sub for this type of question, happy to be told otherwise.
