Welcome, everyone to this Youtube tutorial!
Today, I will be showing you ‘How to join two tables in MySQL (Database)’. As you may already know, MySQL is a commonly used structured query language (SQL) that is used to maintain and manage a database.

Before we begin, you should have a basic understanding of how the MySQL database is designed, as well as how to create and manage a database table with the SELECT, INSERT, UPDATE, and DELETE commands. With that out of the way, let’s get started!

First, let’s discuss what exactly a ‘join’ is. A join is a command that allows us to take two or more tables and link them in a way that provides us with information from both tables. It’s a very useful tool, as it can enable us to work with multiple sets of data at the same time.

Now that we know what a join is, let’s have a look at the syntax we’ll need to use to join two tables. The syntax we’ll use is as follows:

SELECT *
FROM table1
JOIN table2

Now, let’s go through each of the components of this syntax. The SELECT statement is used to select the columns you want to view as part of the joined tables. The FROM statement is used to specify the table you want to query; in this case, we’re using two tables, table1 and table2. The JOIN component joins the two tables. Finally, the ON component links the two tables together on a specific column.

So, to recap: Joins are used to link two or more tables together and provide us with data from both tables. The syntax we use has four components, the SELECT statement, the FROM statement, the JOIN component, and the ON component.

For those of you who are already familiar with the syntax, we’ll take a look at a practical example. Let’s say we want to join two tables called ‘customers’ and ‘orders’. Both tables have a unique id field and the query we’d use to join them would be:

SELECT *
FROM customer
JOIN
