I am working on a project that has synonyms exposed to us for development but when we use them in our EntityObjects/ViewObjects we are getting all the attributes(columns) from the database table as primary key. I tried checking the database tables in the Jdeveloper but its not showing the table constraints but the same is working in Toad.
I am using Jdeveloper - 12c version.

I am a beginner in this. I am working on this ASP.NET Core MVC project where I have two tables: Locations and History. I had created the two tables using Code-First Approach from Visual Studio 2017 Package Manager Console. Due to some reasons, I had to drop the two tables. I deleted the two Models: Locations and History. Then I created a new Migration, following which I updated the database. On checking the Database from SQL Server Management Studio, I see that the tables are not there.
Now, I want to create the same two tables with some changes. When I am trying to add the tables to the database using Code-First Approach where I am typing the command update-database in the NuGet Package Manager Console, I get the following error:
Error Number:3701,State:5,Class:11
Cannot drop the table 'History', because it does not exist or you do not have permission.
However on checking in the database, I am not seeing the table. I even checked for the table by executing the select * from History query which gives results in
Invalid object name 'History'.
I feel that there is a mismatch between the Database and my Project. What to do?
For a given Oracle Database (ODB) 12c table you have the chance to create a CRUD-style API using JDeveloper or SQL Developer by right clicking on it.
Before considering creating a query for several tables that are related to each other with a primary key, I want to know if it is possible to create an API if I create a view for these tables? Particularly the Insert?
The database normalization is very strict from the side of our customer.
The answer is NO, You cannot have a table API from a view with Jdeveloper or SQL Developer by right click on i

You might look into SQL Developer Data Modeler. You should be able to reverse engineer an ER diagram.
i have two sites that sell the same products (same database structure and everything). One of them has recently had all its products updated and we need to take the data from three tables on the updated site and override those same three tables on the out of date site. is there a way to do this is Sql Server MS? ive tried truncating the tables in sql to then do a "insert into db1table select * from db2table" but i just get errors from the foreign keys. Someone showed me a trick a while in visual studio enterprise for comparing data where vs spits out a .sql file you can run to update your table but i only have vs professional 2010 and this doesnt seem to be part of the package.
Assuming you have the same foreign key constraints in both the databases and if foreign key constraints are the only issue -
why don't you just
1) Disable all the foreign keys
2) Load the data
3) Enable all the foreign keys
I come from Oracle background, it should not be very hard to disable/enable all foreign key constraints using a script at one go in SQL Server too.
