🗂️ Table Structure for Practice:
Table: Employees
| id | name | department | salary | join_date |
|---|---|---|---|---|
| 1 | Alice | Sales | 50000 | 2021-01-01 |
| 2 | Bob | Marketing | 45000 | 2020-03-15 |

| 4 | David | Sales | 52000 | 2019-09-20 |
| 5 | Eva | HR | 40000 | 2021-11-05 |
🔹 Basic SQL Queries for Beginners
- Select all records from a table
SELECT * FROM Employees;
- Retrieve specific columns
SELECT name, salary FROM Employees;
- Filter with WHERE clause
SELECT * FROM Employees WHERE department = 'Sales';
- Order results
SELECT * FROM Employees ORDER BY salary DESC;
- Limit number of results
sqlCopyEditSELECT * FROM Employees LIMIT 3;
🔹 Intermediate Practice Queries
- Count number of employees
SELECT COUNT(*) FROM Employees;
- Find highest salary
SELECT MAX(salary) FROM Employees;
- Group by department
SELECT department, COUNT(*) FROM Employees GROUP BY department;
- Average salary per department
SELECT department, AVG(salary) FROM Employees GROUP BY department;
- Employees who joined after 2020
SELECT * FROM Employees WHERE join_date > '2020-01-01';
🔹 JOINs and Subqueries for Beginners
If you have another table like Departments, you can try:
SELECT e.name, d.dept_name
FROM Employees e
JOIN Departments d ON e.department = d.id;
Or try a subquery:
SELECT name FROM Employees
WHERE salary > (SELECT AVG(salary) FROM Employees);
💬 Tips to Practice SQL Queries Effectively
🔹 Don’t just copy-paste—write manually
🔹 Modify queries to test different scenarios
🔹 Try to predict the output before running
🔹 Break down complex queries into parts
🔹 Document what each clause (WHERE, GROUP BY, etc.) does
