Once we implemented the above command, we will get the below result.
SELECT L_ID, luxury_car_names, S_ID, sports_car_names In the below example, we will use the Create command to create a Luxury_cars table. Here, we will be creating and inserting the two different tables where we perform actions on several types of joins: Let us see some examples of different types of PostgreSQL joins: The below image displays most importantly used PostgreSQL joins, which we are going to explain in this section of the PostgreSQL tutorial. In PostgreSQL, we have various types of joins which are as follows:
Usually, the standard columns of the first table are primary key columns and the second table columns are foreign key columns. It is used to merge columns from one or more tables according to the data of the standard columns between connected tables. Whenever we want to get records from two or more tables, we will execute the joins commands. And we can merge the Select and Joins statements together into a single command. PostgreSQL JOINS are used with SELECT command, which helps us to retrieve data from various tables. In this section, we are going to understand the working of several types of PostgreSQL joins, such as Inner join, Left join, Right join, and Full Outer join in brief.
