Q: write inner join statement that generate the output of two tables?

Ans: An INNER JOIN is used to retrieve data from multiple tables based on a related column between them. The basic syntax of an INNER JOIN statement is as follows:

SELECT column_name(s) FROM table1 INNER JOIN table2 ON table1.column_name = table2.column_name;

Here, "table1" and "table2" are the names of the tables you want to join, and "column_name" is the name of the column that links the two tables together.

For example, let's say you have two tables, "customers" and "orders", and they are related by the "customer_id" column. You can use the following INNER JOIN statement to retrieve all the information of customers and their corresponding orders:

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

This query would return all rows where the customer_id in the customers table matches the customer_id in the orders table, along with the selected columns from both tables.

Additionally, you can use * to select all the columns from both tables.

SELECT * FROM customers INNER JOIN orders ON customers.customer_id = orders.customer_id;

It's important to note that the result set will have all the columns from both tables with the same column name from both tables will be repeated.
