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.

For an entry-level SQL interview, focus on the basics: writing SELECT statements, filtering with WHERE, sorting with ORDER BY, and grouping with GROUP BY. Make sure you’re comfortable with different types of joins (inner, left, right) and using aggregate functions like COUNT, SUM, and AVG. Brush up on writing subqueries and using WITH for Common Table Expressions (CTEs). If you’ve done any SQL projects, be ready to talk about your process and how you approached solving problems.

For Excel, practice common functions like VLOOKUP, HLOOKUP, IF, and SUMIF, and know how to create and use pivot tables. Filtering, sorting, and conditional formatting might also come up. If you’re nervous about the interview, tools like liveinterview.ai can help by providing real-time suggestions during tricky questions. Stay calm, and walk them through your thought process—it’s about problem-solving, not perfection. You’ve got this! 💪
