Keeping an Imported Table up to date

Question

Hi Everyone,
I'm reasonably new to SQL, and I'm hoping someone can help me.
I have an Oracle data view that I've imported in to a database on my SQL Server 2012 server. I'd like to setup a way to ensure that the data remains accurate on the SQL Server by checking regularly for changes on the oracle server or by re-importing the
data on say an hourly basis.
Is this possible and if so where do I need to start looking. I'm guessing it's either a maintenance job or a Data Collection job, but if someone could point me in the right direction, I'd be really grateful.
Many thanks in advance
Neil

Hi Guys,
Still having issues, I'm afraid. So that anyone reading this can get an idea of where I'm hitting issues here's what I've done so far:
1) I created a database which I then imported a table to, from an Oracle Server, this worked without fault all rows imported without issue.
2) I created (as advised above) a linked server using the following code:
USE [master]
GO
EXEC master.dbo.sp_addlinkedserver
@server = 'OracleDBs'
,@srvproduct = 'Oracle'
,@provider = 'MSDASQL'
,@datasrc = ''
GO
EXEC master.dbo.sp_addlinkedsrvlogin
@rmtsrvname = 'OracleDBs'
,@useself = 'False'
,@locallogin = NULL
,@rmtuser = ''
,@rmtpassword = ''
GO
To clarify I did enter the data source server name and the rmt username and password. To check the server I expanded the Linked Server, expanded the Catalogs, the default database and the Tables folder and found all of expected data.
3) I opened a new query which I opened against my database from number 1 in this list. In that query I entered the following T-SQL:
TRUNCATE TABLE Table_1
INSERT INTO Table_1 SELECT * FROM OracleDBs.default.<SCHEMA>.Table_1
When I enter this the query recognises both the table to truncate and the table to insert in to (which are both the same table) but all I get is a red underline to the linked server details which upon hover states that it is an invalid object name.
Any help here would be great.

Hi Neil,
According to your description, I do a test about truncating a table to insert the target table in SQL Server 2012, even if it has a red underline to the linked server which states an invalid object name, you can still run well. We need to verify if you can
execute successfully or there will some errors. If failed, please post the error message for analysis.
When you creating Linked Server in MS SQL that points to Oracle. You have to install Oracle Client there on the MS SQL host. If you insert data from Oracle to SQL Server, you can use the following statement.
truncate target_table;  
insert into target_table select * from oracle_linked_server.schema.table;
There is more detail about setting up linked servers for SQL Server and Oracle 64 bit client.
