How to use SQL Select query?

The SELECT query is used to retrieve data from one or more tables in a database. Here is a basic example of a SELECT query in SQL:

[PHP]
SELECT name, email
FROM customers
WHERE city = ‘London’;
[/PHP]

It’s also possible to join multiple tables and retrieve data from them using the SELECT query. Here’s an example:

SELECT orders.order_id, customers.name, products.product_name
FROM orders
JOIN customers ON orders.customer_id = customers.customer_id
JOIN products ON orders.product_id = products.product_id;

This query retrieves the order ID, customer name, and product name for all orders by joining the orders, customers, and products tables on their respective IDs.
