difference between joins and subquery

Comment

SQL Joins and Subqueries. An SQL Join statement is used to combine data or rows from two or more tables based on a common field between them. A subquery is a query that is nested inside a SELECT , INSERT , UPDATE , or DELETE statement, or inside another subquery.

SELECT Customers.customer_id, Customers.first_name, Orders.amount
FROM Customers
INNER JOIN Orders
ON Customers.customer_id = Orders.customer
WHERE Orders.amount >= 500;


SELECT column_name
 FROM table_name1
WHERE VALUE IN 
(SELECT column_name
FROM table_name2 
WHERE condition)
