Using Oracle Heterogenous services to access sql server database table

Question

I have created a dblink 'POC_HS' from oracle to sql (implemented heterogeneous services) and I am able to successfully pull out data from the default database that the DSN(for sql server) is connected to.
So this 'select * from Test@POC_HS' is working perfectly fine on the Oracle database as 'Test' table resides in the default database (which the System DSN is connected to).
But when I do 'select * Abc.Test@POC_HS' where Test table resides in 'ABC' database which is not the default database throws an error as follows:
ORA-00942: table or view does not exist [Generic Connectivity Using ODBC][Microsoft][ODBC SQL Server Driver][SQL Server]Invalid object name 'Abc.Test'.[Microsoft][ODBC SQL Server Driver][SQL Server]Statement(s) could not be prepared. (SQL State: S0002; SQL Code: 208)
I have also tried this 'select * from Abc.dbo.Test@POC_HS' but oracle throws this exception "ORA-00933: SQL command not properly ended".
The dblink user and System DSN account has access to the 'Abc' database.
Thoughts?

Thanks for the info.
But suppose if we have DB link 'POC_HS' where POC_HS is a DBlink between oracle servers, I can do the following -
1. select * Abc.Test@POC_HS
2. select * Def.Test@POC_HS
where Abc,Def are the schemas which the Dblink user has access to. I can execute the above perfectly fine.
I wanted the achieve the same functionality from Oracle to Sql where database keep on changing dynamically . So according to you that's not possible right?
We will have to keep on changing the ODBC connection to a different database or create a new odbc/listener/tnsentry each time query uses a different database right?
