Create Inner Join in Pipeline
Introduction
An INNER JOIN is such type of join that returns all rows from both the participating tables where the key record of one table is equal to the key records of another table. This type of join required a comparison operator to match rows from the participating tables based on a common field or column of both the tables.
From Pipeline Inner join you will learn to create a Pipeline that contains two tables having joined from two or more rows. The inner join selects all the same rows of the tables.
Prerequisites
To Schedule a Pipeline, you need working Parameter Datasets(JDBC) and a list of tables and views.
