ABAP SELECT inner join statement to select from two tables at the same time This example ABAP report demonstrates how to implement a basic SELECT INNER JOIN between two tables (i.e. EKPO and EKET). It then displays the output using a very basic objects based ALV grid. Example ABAP Coding See Joins. Results set for outer joins In principle, the outer join creates the same results set as the inner join, with the difference that, for each selected row on the left side, at least one row is created in the results set, even if no rows on the right side fulfill the condition joincond.
A Watch works like a database table just. But it will not occupy storage area. A look at acts very similar to a virtual desk - a desk that does not possess any physical existence. A see is produced by combining the information of one or more tables containing details about an program object. Making use of views, you can represent a subset of the data contained in a desk or you can sign up for multiple desks into a individual virtual desk.
Data related to an application object is certainly dispersed among several tables by making use of data source views. They make use of the internal join situation to sign up for the data of various tables. A servicing view is utilized to screen and change the data stored in an application item. Every upkeep view provides a maintenance status linked with it.
Wé make use of projection see to mask unwanted fields and screen only appropriate fields in a desk. Projection views must end up being described over a single transparent desk. A projection view contains specifically one desk. We can't define selection problems for projection viéws.
