Here, EmployeeId is the common column that is available in all the tables and based on this column we are going to perform the Left Outer Join Operations. To understand Left Outer Join, we are going to use the following Employee, Address, and Projects tables. Let us understand how to implement Left Outer Join in Oracle with Examples. In that case, the non-matching rows will take a null value. If you want to retrieve all the matching rows from both the tables involved in the join as well as all the non-matching rows from the left side table in the result set then you need to use Left Join in Oracle. When do we need to use Left JOIN in Oracle? That means if you use the LEFT JOIN keyword, then also it is going to perform Left Outer JOIN Operation. As you can see in the below image, we can use either the LEFT OUTER JOIN or the LEFT JOIN keyword to perform the Left Join operation in Oracle. The following images show how to use Left Outer Join in Oracle. How to implement Left Outer Join in Oracle? The following diagram shows the pictorial representation of Left Outer Join. The question that should come to your mind is which is the left table and which is the right table? The answer is, the table which is mentioned to the left of the LEFT OUTER JOIN keyword is the left table, and the table which is mentioned to the right of the LEFT OUTER JOIN keyword is the right table. The LEFT OUTER JOIN or LEFT JOIN keyword is used to perform the left join in Oracle. In that case, the non-matching data will take a null value. The Left Outer Join in Oracle is used to retrieve all the matching records from both the tables as well as non-matching records from the left side table.
