A JOIN clause is used when you need to combine data from two or more tables into one data set. Records from both tables are matched based on a condition (also called a JOIN predicate) you specify in the JOIN clause. If the condition is met, the records are included in the output.

A JOIN clause is used to join rows from two or more tables based on a common column. It’s worth noting that the “CustomerID” column in the “Orders” table corresponds to the “CustomerID” column in the “Customers” dataset.
