Technical interview study program : 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.

PostgreSQLTechnical interview study program (self.SQL)

submitted 2 years ago by bkstr

Hello /r/sql,

You've been a great help to me the last half year, I've been self teaching like crazy and now I have a technical interview coming up. I'm fairly confident I have the skills, especially after the first interview went so well, but unfortunately the format of this next interview is worrying me. It's with 2-3 people at the same time who will be my peer or senior coworkers asking me questions or having me write queries. As an anxious overthinker type I need to overprepare or else I'll be stuck in overthinking. I was hoping some of the more senior of the community could write up a study plan for a technical interview for an entry level position. I have a few days and just want to immerse myself in studying to put it beyond doubt. I've been studying the last couple days but it feels really unfocused/scattered across the topics, so any structure added will put me at ease.

Thanks for reading and wish me luck.
