JOINS
Definition
Joins in MySQL allow you to retrieve data from two or more tables based on a related column. They are used to combine rows from multiple tables.
Types of Joins
1. INNER JOIN:
- Returns rows where there is a match in both tables.
- Syntax:
- Example:
2. LEFT JOIN (OUTER JOIN):
- Returns all rows from the left table and matching rows from the right table. Non-matching rows have
- Example:
3. RIGHT JOIN (OUTER JOIN):
- Returns all rows from the right table and matching rows from the left table. Non-matching rows have
- Example:
4. FULL OUTER JOIN:
- Returns all rows from both tables, matching where possible. Not natively supported in MySQL, but can be simulated using
- Example:
5. CROSS JOIN:
- Returns the Cartesian product of both tables.
- Example:
Interview Questions
1. What is the difference between INNER JOIN and OUTER JOIN?

Joins in MySQL allow you to retrieve data from two or more tables based on a related column. They are used to combine rows from multiple tables.
Types of Joins
1. INNER JOIN:
- Returns rows where there is a match in both tables.
- Syntax:
SELECT columns
FROM table1
INNER JOIN table2
ON table1.column = table2.column;
- Example:
SELECT employees.name, departments.name
FROM employees
INNER JOIN departments
ON employees.department_id = departments.id;
2. LEFT JOIN (OUTER JOIN):
- Returns all rows from the left table and matching rows from the right table. Non-matching rows have
NULL.- Example:
SELECT employees.name, departments.name
FROM employees
LEFT JOIN departments
ON employees.department_id = departments.id;
3. RIGHT JOIN (OUTER JOIN):
- Returns all rows from the right table and matching rows from the left table. Non-matching rows have
NULL.- Example:
SELECT employees.name, departments.name
FROM employees
RIGHT JOIN departments
ON employees.department_id = departments.id;
4. FULL OUTER JOIN:
- Returns all rows from both tables, matching where possible. Not natively supported in MySQL, but can be simulated using
UNION.- Example:
SELECT employees.name, departments.name
FROM employees
LEFT JOIN departments
ON employees.department_id = departments.id
UNION
SELECT employees.name, departments.name
FROM employees
RIGHT JOIN departments
ON employees.department_id = departments.id;
5. CROSS JOIN:
- Returns the Cartesian product of both tables.
- Example:
SELECT employees.name, departments.name
FROM employees
CROSS JOIN departments;
Interview Questions
1. What is the difference between INNER JOIN and OUTER JOIN?
- INNER JOIN only includes rows with matches in both tables, while OUTER JOIN includes unmatched rows.
2. How can you simulate a FULL OUTER JOIN in MySQL?
- Use
UNION of LEFT JOIN and RIGHT JOIN.3. What is a Cartesian product, and when does it occur?
- A Cartesian product occurs in a
CROSS JOIN or when no ON condition is specified, resulting in all possible row combinations.โค1
