![]() ![]() Let us see an example to understand how the PostgreSQL Full Outer join works: To join two tables by using PostgreSQL Full Outer Joinįor this, we will create two tables named Summer_fruits and Winter_fruits table with the help of the CREATE command and insert some values using the INSERT command.įirstly, we are going to create Summer_fruits and Winter_fruits tables by using the CREATE command: And lastly, we will describe the Left table, which is table 1 in the Full Outer Join clause, and write the join condition after the ON keyword.Then, we will specify the Right table, which is table 2 in the FROM clause.Firstly, we will define the column list from both tables, where we want to select data in the SELECT condition.We will follow the below steps to combine the Left and Right tables with the help of the Full Join or Full Outer Join condition: In the above syntax, The Full Outer Join keyword is used with the SELECT command and must be written after the FROM Keyword, and the OUTER keyword is optional. The syntax for Full Outer Join or Full Join is as following: The following Venn diagram displays the PostgreSQL Full Outer Join where we can easily understand that the Full Outer Join returns all the data from both the Left table and Right table: Syntax of PostgreSQL Full Outer Join ![]() The main objective of a Full Outer Join is that it will combine the outcome of PostgreSQL Left Join and PostgreSQL Right Join clauses and returns all similar or unmatched rows from the tables on both sides of the join clause. The PostgreSQL Full Join or Full Outer Join is used to return all records when there is a match in the left table or right table records. What is the PostgreSQL Full Join or Full Outer Join clause? ![]() We also learn how to use table-aliasing, WHERE clause with the help of the PostgreSQL Full Outer join clause. In this section, we are going to understand the working of PostgreSQL Full join, which is used to return all records when there is a match in the left table or right table records. ![]()
