Hello everybody,
What is the reason for the self-join in the table without making any changes to the physical model in the repository in Oracle BI?
Could you help me?
Thank you,
The resulting model is as follows.
Well, It didn't create itself so probably you did this yourself by accident. You can just delete it
In addition to Martin's point (which is definitely a +10000 : keep your RPD clean), if you are asking more from a "will this be an issue" point of view the answer is not: physical joins aren't used if you don't have something in the business model using the physical objects and requiring to go through that join to connect to something else.
If you imported the physical objects including foreign keys etc. your self-join can probably come from there and so it's more something used by the DB itself to keep data quality (by allowing only data matching the foreign key, for example an "employees" table with a column being "manager ID" and the manager is an employee as well).
After upgrading from version 11.1.1.7 to 11.1.1.9 in Oracle BI, some of our models have changed in this way. There have been some warnings in the RPD. The problem can be solved if I can fix the warnings :S
Why didn't you tell you did an upgrade when you first posted this? That is obviously important information. Also the warnings may provide valid information we need to be able to help.
You may have hit a bug, See: I suggest you follow Ian's Advice on this .
If there's only a few joins that have changed you can probably fix your problems by recreating the original joins and the warnings will likely be gone.
I forgot to share this information, you are right. Thank you so much for the redirect.

What is wrong with this code
Am I missing something or is there no way to search through previous posts to make sure I don't duplicate a question? All I see on the filter options are tags or status… a general search for a word or phrase would be helpful.
We were under the impression that when exporting a visualization in DV to CSV format hidden columns would be include from the grammar panel. This is not happening. See below for a screenshot showing 3 hidden columns that do not appear when exporting the pivot table to CSV. This seems to have worked a month or so back but…
