Master the core SQL statementsโthey are the building blocks of every powerful query you'll write.
-> SELECT retrieves data efficiently and accurately. Remember, clarity starts with understanding the result set you need.
-> WHERE filters data to show only the insights that matter. Precision is key.
-> CREATE, INSERT, UPDATE, DELETE allow you to mold your database like an artistโdesign it, fill it, improve it, or even clean it up.
In a world where everyone wants to take, give knowledge back.
Become an alchemist of your life. Learn, share, and build solutions.
Always follow best practices in SQL to avoid mistakes like missing WHERE in an UPDATE or DELETE. These oversights can cause chaos!
Without WHERE, you risk updating or deleting entire datasets unintentionally. That's a costly mistake.
But with proper syntax and habits, your databases will be secure, efficient, and insightful.
SQL is not just a skillโit's a mindset of precision, logic, and innovation.

Getting started with SQL comparison operators.
If you're new to SQL, understanding comparison operators is one of the first things you'll need to learn.
Theyโre really important for filtering and analyzing your data. Letโs break them down with some simple examples.
Comparison operators let you compare values in SQL queries. Here are the basics:
1. = (Equal To): Checks if two values are the same.
Example: SELECT * FROM Employees WHERE Age = 30; (This will find all employees who are exactly 30 years old).
2. <> or != (Not Equal To): Checks if two values are different.
Example: SELECT * FROM Employees WHERE Age <> 30; (This will find all employees who are not 30 years old).
3. > (Greater Than): Checks if a value is larger.
Example: SELECT * FROM Employees WHERE Salary > 50000; (This will list all employees earning more than 50,000).
4. < (Less Than): Checks if a value is smaller.
Example: SELECT * FROM Employees WHERE Salary < 50000; (This will show all employees earning less than 50,000).
5. >= (Greater Than or Equal To): Checks if a value is larger or equal.
Example: SELECT * FROM Employees WHERE Age >= 25; (This will find all employees who are 25 years old or older).
6. <= (Less Than or Equal To): Checks if a value is smaller or equal.
Example: SELECT * FROM Employees WHERE Age <= 30; (This will find all employees who are 30 years old or younger).
These simple operators can help you get more accurate results in your SQL queries.
Keep practicing and youโll be great at SQL in no time.

SQL is one of the core languages used in data science, powering everything from quick data retrieval to complex deep dive analysis. Whether you're a seasoned data scientist or just starting out, mastering SQL can boost your ability to analyze data, create robust pipelines, and deliver actionable insights.
Letโs dive into a comprehensive guide on SQL for Data Science!
I have broken it down into three key sections to help you:
๐ญ. ๐ฆ๐ค๐ ๐๐ผ๐ป๐ฐ๐ฒ๐ฝ๐๐:
Get a handle on the essentials -> SELECT statements, filtering, aggregations, joins, window functions, and more.
๐ฎ. ๐ฆ๐ค๐ ๐ถ๐ป ๐๐ฎ๐-๐๐ผ-๐๐ฎ๐ ๐๐ฎ๐๐ฎ ๐ฆ๐ฐ๐ถ๐ฒ๐ป๐ฐ๐ฒ:
See how SQL fits into the daily data science workflow. From quick data queries and deep-dive analysis to building pipelines and dashboards, SQL is really useful for data scientists, especially for product data scientists.
๐ฏ. ๐๐ฎ๐๐ฎ ๐ฆ๐ฐ๐ถ๐ฒ๐ป๐ฐ๐ฒ ๐ฆ๐ค๐ ๐๐ป๐๐ฒ๐ฟ๐๐ถ๐ฒ๐๐:
Learn what interviewers look for in terms of technical skills, design and engineering expertise, communication abilities, and the importance of speed and accuracy.
