Create Right Join in Pipeline.

Introduction​

The RIGHT JOIN combines data from two or more tables. The RIGHT JOIN clause starts selecting data from the right table and matching it with the rows from the left table. The RIGHT JOIN returns a result set that includes all rows in the right table, whether or not they have matching rows from the left table.

From this document, you will learn how to create the Pipeline, which contains the right join, here the right join connects the multiple tables to make the Pipeline.

Prerequisites​

To Schedule a Pipeline, you need working Parameter Datasets(JDBC) and a list of tables and views.
