 Q: Design any two queries that apply inner join and left join depending on your relational schema.?

Ans: Here are examples of two SQL queries, one using an INNER JOIN and one using a LEFT JOIN:

INNER JOIN:e

SELECT customers.name, orders.total_amount
FROM customers 
INNER JOIN orders 
ON customers.customer_id = orders.customer_id;

This query retrieves the name of customers from the "customers" table and the total amount of orders from the "orders" table by matching the customer_id in both tables. The INNER JOIN clause only returns the rows where the customer_id matches in both tables.

LEFT JOIN:

SELECT products.name, orders.quantity
FROM products
LEFT JOIN orders
ON products.product_id = orders.product_id;

This query retrieves the name of products from the "products" table and the quantity of orders from the "orders" table by matching the product_id in both tables. The LEFT JOIN clause returns all the rows from the left table (products), and the matching rows from the right table (orders). If there is no match, NULL values will be returned for the right table's columns.

Please keep in mind that table names, column names, and the actual query may vary depending on the database structure and naming conventions used. Also, the data that is returned by these queries might be different depending on the data stored in the tables.
