r/SQL

Be polite and civil

/r/SQL is a community of professionals and hobbyists who are united in a love of data, analytics, and the like.

Let's embrace the things that we have in common. Don't be rude or unpleasant. Do not harass others. Don't resort to value judgments. Don't resort to personal attacks.

Do not post links to basic SQL tutorials

/r/SQL does not allow links to basic tutorials to be posted. You should post these to /r/learnsql instead.

Please see this discussion to understand why the community made this decision.

Tell us what DBMS / SQL variant you are using

When requesting help or asking questions, please flair your post with the DBMS (database management system) / SQL variant that you are using.

If you include any of the following in your title, your post will receive the appropriate flair automatically: MySQL, Oracle, MS SQL, PostgreSQL, SQLite, DB2, MariaDB

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.

Provide as much context/background info as possible

If you are a student or just looking for help on your code, please do not just post your questions and expect the community to do all the work for you. We will gladly help where we can as long as you post the work you have already done or show that you have attempted to figure it out on your own.

Additionally, providing your current query (even if it is not functioning as intended), table columns, example data, and so forth will all make it easier for the community to assist you.

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.

To format your code using reddit's built in code formatting, put 4 spaces at the start of each line.

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.

No photos of lengthy code

Please see rule #3 - copy/paste lengthy code (and output, error messages, etc.) and format them.

Photographs of computer screens with code on them are inconvenient; they are difficult to read and mean others can't copy/paste to help you with solutions.

Make it easy for people to help you! Don't paste photos of screens.

No solicitation for others to do your homework

Do not post seeking assistance with homework questions of any kind (including take home interview content) without a demonstrable good faith attempt to find solutions on your own
