What are the differences between SQL Joins and Subqueries?

What are the differences between SQL Joins and Subqueries?

SQL Joins combine rows from two or more tables based on a related column, while Subqueries are nested queries within another query.

Can you give me an example of a Join?

Sure! A simple example is an INNER JOIN that retrieves records from two tables where there is a match. For instance: SELECT * FROM Orders INNER JOIN Customers ON Orders.CustomerID = Customers.CustomerID.

And what about a Subquery?

A Subquery example could be: SELECT * FROM Customers WHERE CustomerID IN (SELECT CustomerID FROM Orders WHERE OrderAmount > 100).

When should I use Joins instead of Subqueries?

Use Joins for better performance and readability when combining data from multiple tables, and Subqueries for filtering results based on another query.
