linked server compares between Oracle and SQL Server - sql-server

We are doing a migration from Oracle 10g to SQL Server 2014. Once I set up the linked Server connection in SQL Server to the Oracle DB will I be able to run a statement like the following:
select * from linkedservername...schema.table
except
select * from Servername.database.schema.table
Not all queries will be this easy as I'll have to do some data manipulation on the oracle side. Will I need to use Oracle syntax for that or once I have the linked server set up will everything be in T-SQL for querying purposes?
Thanks

How can I move data from SQL Server to Oracle?

I have created my database and tables in a SQL Server Express database. And now I migrated the database tables to Oracle with Entity Framework. But my tables are empty in Oracle. How can I move my data to Oracle?
Use SSIS interface from MS-SQL (Sql Server Integration Service).
I have used to move content from MSSQL to MySQL you should use the correct odbc driver.
For express edition, You can use Linked Servers to establish connection between SQL Server and Oracle. In this way, you should insert the records by creating queries for per table.

How to connect remotely to server using sql studio

I am new to SQL but this is what i would like to do.

hostname: hostname.com
port: 1523
SID: oracledb
Username: username
Password: password
I would like to connect remotely to this server to retrieve data using MSSQL studio. Can you please explain to me how to do it. thank you
You cannot directly connect to and query an Oracle database using SQL Server Management Studio. You can, however, create a SQL Server linked server to your Oracle instance and query remotely through that. You would connect to your SQL Server using SSMS like normal, but query your linked server using the linked server name in 4-part naming fashion, e.g: select * from [MyOracleServer]..MyDatabase.MyTable.
Here is a SQLMag tutorial on doing this: Connecting SQL Server and Oracle Using Linked Servers.

Also in order to migrate an Oracle database to SQL Server, we can use
SSMA (SQL Server Migration Assistant for Oracle)
There is a migration assistant available for Oracle to SQL Server

Connecting Oracle to Microsoft SQL Server on 2 different servers

I am trying to make a connection between Oracle and SQL Server to insert some values from Oracle into SQL Server. I have 2 questions which i was hoping you can help.
There is a stored procedure created in Oracle 11g database. It joins a few tables together and pushes the values into a table called my_table in SQL Server.
The issue/question I have: I've tried to make a connection between Oracle and SQL Server using this link: Making a Connection from Oracle to SQL Server - Page 2 — DatabaseJournal.com
The instruction is however for when Oracle and SQL Server are on a same server.
As is my case Oracle is on one server and SQL Server is on another, I am struggling to understand the concept of setting up Listener and tbs.
Do I have to do any configuration on SQL Server? Do I need to create the DNS on SQL Server?
When I create a DNS in Oracle server, the connection to SQL Server is successful (port 1433) but I'm not sure how to alter my Listener and TNS for that.
My Oracle knowledge is not advanced but so far I've managed to get to this point. Hope you can help me resolve the last bit of the puzzle.

Linked Server as Database

I successfully created a linked postgresql server in SQL Server 2008. I can also query results using
SELECT * FROM OPENQUERY(POSTGRES32,'SELECT * FROM public.categories')
Is there a way to treat that linked server (Postgresql) as a SQL Server database?
