🎯 The Only SQL You Actually Need For Your First Data Analytics Job

🚫 Avoid the Learning Trap: 
Watching 100+ tutorials but no hands-on practice.

✅ Reality: 
75% of real SQL work boils down to these essentials:

1️⃣ SELECT, FROM, WHERE
⦁ Pick columns, tables, and filter rows

SELECT name, age FROM customers WHERE age > 30;

2️⃣ JOINs
⦁ Combine related tables (INNER JOIN, LEFT JOIN)

SELECT o.id, c.name FROM orders o JOIN customers c ON o.customer_id = c.id;

3️⃣ GROUP BY
⦁ Aggregate data by groups

SELECT country, COUNT(*) FROM users GROUP BY country;

4️⃣ ORDER BY
⦁ Sort results ascending or descending

SELECT name, score FROM students ORDER BY score DESC;

5️⃣ Aggregation Functions
⦁ COUNT(), SUM(), AVG(), MIN(), MAX()

SELECT AVG(salary) FROM employees;

6️⃣ ROW_NUMBER()
⦁ Rank rows within partitions

SELECT name,
ROW_NUMBER() OVER (PARTITION BY department ORDER BY salary DESC) AS rank
FROM employees;

💡 Final Tip: 
Master these basics well, practice hands-on, and build up confidence!

*🚀 SQL Interview Questions with Answers — Made Easy!*

*1. How to rename a table in SQL?*
Use this command:
ALTER TABLE old_table_name RENAME TO new_table_name;
→ Simple: use ALTER, mention the current name, then RENAME TO and the new name. ✅

*2. How to use LIKE in SQL?*
Use LIKE to match patterns:
SELECT * FROM employees WHERE first_name LIKE 'Steven';
→ It fetches all rows where first_name is exactly “Steven”.

*3. Does dropping a table delete related objects too?*
Yes ✅: Constraints, indexes, columns, and defaults *inside* the table are deleted.
No ❌: Views and stored procedures stay — they exist *outside* the table.

*4. What are SQL Constraints?*
They define rules on table data. Common constraints include:
NOT NULL, CHECK, DEFAULT, UNIQUE, PRIMARY KEY, FOREIGN KEY

Coursera interview experience
Role - ML engineer

It started with his introduction and then mine. Next he gave me one hackerrank link to solve live a medium to hard level leetcode question based on arrays. After completing that, he asked me few ML based questions like type of learning and their explanations and a few examples. Also asked me to classify 2 examples about what ML model might be suitable for that case. Also he asked me a few SQL queries. Then he asked me to choose a project which i did and asked me to explain it and cross questioned about that. At last he gave me a chance to ask a few questions.

🔹 What is the Bandwagon Effect?

The Bandwagon Effect is a psychological bias in which people start doing something simply because everyone else is doing it.

👉 That is, a person doesn't think whether something is right or not, they just follow the crowd.
This is called —

"Everyone is doing it, so I will too."

🔹 Real-life examples 👇

Fashion trends 👗
When a new style or clothing item becomes trendy, people start wearing it,
even if it doesn't suit them — just because everyone else is wearing it.

Social media following 📱
When a celebrity or influencer becomes very popular,
people start following them without any particular reason,
because “everyone is following them.”

Voting in elections 🗳️
Sometimes people vote for a party just because
“it seems like they are going to win.”
That is, they make decisions based on the majority, not thoughtful consideration.

Stock market / Crypto 💰
When people see others investing in a particular stock or cryptocurrency,
they also invest in it —
without knowing whether it's the right choice or not.

🔹 Psychological reason

Humans feel safe in a crowd (herd mentality).

We fear that “if I am different, I might be wrong.”

That's why we do what others are doing.

🔹 Example from India 🇮🇳

In 2021, when cryptocurrencies like “Dogecoin” and “Shiba Inu” were trending,
millions of Indians invested money just because
“everyone was earning.”
But later, when the market crashed,
most people suffered heavy losses —
because they hadn't done their own research.

✅ Simple definition:

Bandwagon Effect means – when a person starts doing something just because everyone else is doing it.

🕉 Even in matters of religion, people follow new rituals. They don't even know their meaning, yet they follow them. Why? Because if everyone is doing it, it can't be wrong.

But I have learned from Acharya Ji that if everyone is doing something, there's a higher chance that it might be wrong. And I am seeing this happening around me.
