Why are my subqueries slow?

This is why.

Note to self: Only use subqueries ( SELECT * FROM `table1` WHERE `id` IN (SELECT `id` FROM `table2`) ) when it is impossible to achieve the same result using joins.

About

Hello! Welcome to my website! My name is Isabel Nyo and on this website, you will find career resources for professionals in tech. I’ve got almost 20 years of experience in the tech industry, with startups to Fortune 500 tech companies. I started this website in 2005 and for a decade, the main focus was web development. I rebranded my website in 2016 as a career resources portal for professionals in tech.

Want to chat with me for an opportunity, an idea or a speaking engagement? The best way to reach me is via a social media platform. I am on Twitter, LinkedIn, Facebook, Pinterest and Medium.

If you are a woman in technology or an advocate for women in technology, head over to my store for chic, bold, fun and inspirational prints, phone cases, bags, T-shirts, mugs and other accessories that aim to empower and support women in technology.

For my website, I use these resources (and tools).
