I'm using Toad for Oracle v12.0.0.61 with admin module.
the database i'm interested in has 61 "views"
I selected all views, right clicked and chosen ER Diagram
Toad created small UML diagram for each table listing the table name and all their columns, but there are no indication of their primary keys or foreign keys and the relationships between them.
Even if I choose one specific table (main one), and right click on it and choose ER diagram, choosing say 5 level of details, it creates one diagram only for one table without all the other information.
Am I missing any step here or is this related to the level of access I have been given?
Thank you
Views don't have keys. Views are just canned SQL queries.
Best of luck.

I am trying to change a selection table within our packing list menu in our SAP system, but I do not know how to do this. My colleague, who is out indefinitely, has created a table of packing materials for our warehouse staff. This table is now to be extended by two further entries. The selection table is in the packing list table DLN7. I have also shown this in the picture attached.
So far I have checked all custom tables and custom windows. However, the table displayed is not there. Does anyone know where in SAP I have to look?
I would be very happy to receive further hints on this.
Thank you very much in advance.
Context:
I am creating a dashboard in Excel based on the data model I am building in Power Pivot. The source data in the data model is based on various other excel tables I am regularly receiving and copy-pasting into my workbook (their incoming structure is out of my control). My goal is to perform all data processing within Power Pivot/DAX rather than manipulating the data in the worksheets before loading into the model.
Problem:
In my model, I have a table (tabCases) which includes status updates on all cases from a management system. This table has a column named case-ID (not unique). I need to create a lookup-table with unique case-id's where I can create new columns with various KPIs for each case.
How can I do this in Power Pivot?
I found two suggestions in this article but none of them work for me (opt. 1 because it requires a manual creation of the unique ID list and opt. 2 because I don't have a database access).
In my mind there should be something really simple I could do, such as i.e.:
Add new table to data model
Set first column to be equal to DISTINCT(tabCases[caseID])
Is there such a way?
A Linkback Table might help you. Please see the link below:

I have a doctrine data model with a table Person, however my Symfony application is only part of a bigger web application, which is build in Joomla. For a module, I need to add a number of fields from a view, which spans 8 tables with the person table. The view is already established for the Joomla part of things.
Short of creating a schema for all the tables involved, is there a way to arbitrarily join the view in my tableMethod? As another shortcut I am thinking of creating a minimal schema.yml table to just represent the field of the view that I need.
another solution would be to use native sql with doctrine
In Visual Studio 2010 do you have the ability to compare the data of a database between 2 databases. I wanted to use this to copy data from one database to another. These databases have the exact same structure. But when I do a compare I see only 65 tables showing up in de DataCompare view in VS2010 but I have 66 tables in the database.
The next step was to find out which table not was showing up. The name of this table is 'CMS_PluginInstanceRouteParams'. This table is also present in both databases which I also have checked. The structure of this table is:
The FK is a relation to the PK of the CMS_PluginInstance table. The CMS_PluginInstance does show up in the Data Comparison window and the data is also compared and copied.
I also couldn't find a dialog or option where I can enter some table names to ignore.
Does anyone of you know why this table is not showing up in the list of tables in the Data Comparison window and why the data of this table not is compared.
I found the solution on http://social.msdn.microsoft.com/Forums/en-US/vstsdb/thread/d84a758e-79ea-4170-8807-7f8bdec98de1/:
Tables and views must meet two criteria to appear in the listing:
First, the schemas of the objects must match between the source and target database.
Second, only tables and views that have a primary key or a unique key appear in the list.
The DataCompare tool of VS2010 only compares tables that have unique keys. It is most likely that this missing table does not have a unique key. As for transferring data the best bet would be to use SQL Server Management Studios Import and Export tools. You should have no trouble finding guides online.

There are multiple tasks if you want to do this completely. The world at large has not gone this way and so there are not many tools (if any) for this. But basically here are the main ideas.
1) You want a "data dictionary", a collection of meta-data that tells you what the types and sizes of each column are, and the primary and foreign keys are.
2) For your example of "knowing" that a field should be a drop-down, this almost always means that column value is a foreign key to another table. Your code detects this and builds a listbox out of the values in the parent table.
3) You can go so far as to create a complete form generator for simple tables, where all of the HTML is generated, but you always need a way to override this for the more complex forms. If you do this, your data dictionary should also have column descriptions or captions.
There are many many more ideas, but this is the starting point for what you describe.
