SQL CHEAT SHEET — Save This Post!
Most Asked Queries in Tech Interviews!
====================================
SQL is asked in 90% of tech interviews —
TCS, Infosys, Amazon, even AI roles need it!
Master these queries TODAY!
====================================
BASIC QUERIES
SELECT * FROM employees;
-> Get all data from table
SELECT name, salary FROM employees
WHERE salary > 50000;
-> Filter rows with condition
SELECT * FROM employees
ORDER BY salary DESC LIMIT 5;
-> Top 5 highest paid employees
====================================
AGGREGATE FUNCTIONS
SELECT COUNT(*) FROM employees;
-> Total number of rows
SELECT AVG(salary) FROM employees;
-> Average salary
SELECT department, COUNT(*) FROM employees
GROUP BY department;
-> Count employees per department
SELECT department, AVG(salary) FROM employees
GROUP BY department
HAVING AVG(salary) > 60000;
-> Departments with avg salary > 60k
====================================
JOINS — Most Asked in Interviews!
INNER JOIN -> Only matching rows in both tables
SELECT e.name, d.dept_name
FROM employees e
INNER JOIN departments d
ON e.dept_id = d.id;
LEFT JOIN -> All rows from left + matching right
SELECT e.name, d.dept_name
FROM employees e
LEFT JOIN departments d
ON e.dept_id = d.id;
SELF JOIN -> Table joined with itself
SELECT e1.name, e2.name AS manager
FROM employees e1
JOIN employees e2
ON e1.manager_id = e2.id;
====================================
SUBQUERIES — Asked in Advanced Rounds!
Find employees earning more than average:
SELECT name FROM employees
WHERE salary > (
SELECT AVG(salary) FROM employees
);
Find 2nd highest salary (Classic Question!):
SELECT MAX(salary) FROM employees
WHERE salary < (
SELECT MAX(salary) FROM employees
);
====================================
WINDOW FUNCTIONS — Modern SQL!
Rank employees by salary:
SELECT name, salary,
RANK() OVER (ORDER BY salary DESC) as rnk
FROM employees;
Running total of salaries:
SELECT name, salary,
SUM(salary) OVER (ORDER BY id) as running_total
FROM employees;
====================================
MUST-KNOW CONCEPTS:
Primary Key -> Unique identifier for each row
Foreign Key -> Links 2 tables together
Index -> Speeds up search queries
Normalization -> Reduce data redundancy
Transaction -> ACID properties (all or nothing)

SQL CHEAT SHEET - Save This!
Most Asked SQL in Tech Interviews!
====================================
SQL is tested in 90% of tech interviews!
TCS, Infosys, Amazon, Flipkart, Data Analyst
roles ALL require strong SQL. Master this!
====================================
BASIC QUERIES
SELECT * FROM employees;
-> Get all rows from table
SELECT name, salary FROM employees
WHERE salary > 50000;
-> Filter rows with condition
SELECT * FROM employees
ORDER BY salary DESC LIMIT 5;
-> Top 5 highest paid employees
SELECT DISTINCT department FROM employees;
-> Get unique departments only
====================================
AGGREGATE FUNCTIONS
SELECT COUNT(*) FROM employees;
-> Total number of rows
SELECT AVG(salary) FROM employees;
-> Average salary
SELECT MAX(salary), MIN(salary) FROM employees;
-> Highest and lowest salary
SELECT department, COUNT(*) as emp_count
FROM employees
GROUP BY department
HAVING COUNT(*) > 5;
-> Departments with more than 5 employees
====================================
JOINS - Most Asked in Interviews!
INNER JOIN - Only matching rows in both tables:
SELECT e.name, d.dept_name
FROM employees e
INNER JOIN departments d ON e.dept_id = d.id;
LEFT JOIN - All from left + matching right:
SELECT e.name, d.dept_name
FROM employees e
LEFT JOIN departments d ON e.dept_id = d.id;
SELF JOIN - Table joined with itself:
SELECT e1.name, e2.name AS manager
FROM employees e1
JOIN employees e2 ON e1.manager_id = e2.id;
====================================
SUBQUERIES - Asked in Advanced Rounds!
Employees earning more than average:
SELECT name FROM employees
WHERE salary > (SELECT AVG(salary) FROM employees);
2nd highest salary (Classic Question!):
SELECT MAX(salary) FROM employees
WHERE salary < (SELECT MAX(salary) FROM employees);
Nth highest salary using LIMIT:
SELECT salary FROM employees
ORDER BY salary DESC LIMIT 1 OFFSET N-1;
====================================
WINDOW FUNCTIONS - Modern SQL!
Rank employees by salary:
SELECT name, salary,
RANK() OVER (ORDER BY salary DESC) as rnk
FROM employees;
Row number within each department:
SELECT name, department,
ROW_NUMBER() OVER
(PARTITION BY department ORDER BY salary DESC)
FROM employees;
====================================
TOP 5 SQL INTERVIEW QUESTIONS:
1. Find duplicate records in a table
2. Find employees with no manager (NULL)
3. Find departments with zero employees
4. Find Nth highest salary
5. Difference between WHERE and HAVING?
