Save this clip for your next interview prep session.

Stop tripping up on these 6 database concepts in your technical interviews. 👇

Most candidates stumble on the subtle differences between pairs that SOUND identical but work completely differently under the hood like WHERE vs. HAVING or TRUNCATE vs. DELETE.

In this video, I’m breaking down the 6 most commonly confused SQL & database pairs so you can explain them with complete confidence and instantly stand out from the rest:

1️⃣ INNER JOIN vs. LEFT JOIN
2️⃣ WHERE vs. HAVING
3️⃣ UNION vs. UNION ALL
4️⃣ NULL vs. EMPTY STRING
5️⃣ TRUNCATE vs. DELETE
6️⃣ PRIMARY KEY vs. FOREIGN KEY

Save this clip for your next interview prep session, and drop a comment below on which pair always confuses you.

Part 2 on indexing, warehousing, and storage is coming up next.

@datagirlanth Really insightful

Most people finish a bootcamp with three tutorials and no portfolio.

Same output as everyone else, sitting in a repo nobody opens.

Here’s the system I give every grad who asks what next.
