How to create a multiple table join view in SQL?

The basic syntax for creating a multi-table join view is as follows:

Create a view named view_name that selects column1, column2, and other columns from table1, joining with table2 and table3 based on specified conditions, and filtering the results based on condition3.

In this case, view_name is the name of the view, column1, column2, … are the names of the columns to display, table1, table2, … are the names of the tables to join, condition1, condition2, … are the conditions for joining the tables, and condition3 is the condition for filtering the data.

Here is an example demonstrating how to create a multi-table join view.

Create a personalized view called “customer_orders” that includes the customer’s name, order ID, and order date by joining the customers and orders tables on the customer ID.

In the above example, the name of the view is customer_orders, the columns to be displayed are customer_name, order_id, and order_date, customers and orders are the table names to be joined, and the condition to join the tables is c.customer_id = o.customer_id.

After creating a multi-table join view, you can query the view just like you would query a table, for example:

Retrieve all data from the customer_orders view.
