SELECT a.*
FROM OPENROWSET(N'OraOLEDB.Oracle', N'Data Source=Myip:Port/dbname';'User Id=user';'Password=pass;',
'select * FROM view WHERE value = ''102030'' ') AS a;
sql return below error:

I used Linked Server for fetch data but oracle table not small and it takes a long time to execute.

SQLNCLI syntax when using OPENROWSET
We have been using this syntax when using OpenRowset to collect data from other SQL Server instances.
SELECT a.* FROM OPENROWSET('SQLNCLI', 'Server=MyServer;Database=Tasks; User Id=sa;Password=myPassword;','SELECT * FROM Patients') As a;

How to return Oracle XML type via linked server?
OLEDB driver complains as the data type is not supported.
However when you convert the xml to string, it should work.
select * from openquery(oracle_ls,

Calling an Oracle function from SQL Server Linked Server
EXECUTE (Query, Parameters) AT LinkedServerName
I am trying to connect Oracle 9i database using SQL Management studio 2008.
I tried this but it doesn't work
EXEC sp_addlinkedserver 'OracleLinkedServer','Oracle','OraOLEDB.Oracle','TestDB';
EXEC sp_addlinkedsrvlogin 'OracleLinkedServer','false','SA','TestUsername','TestPassword';
I am able to create the linked server and it test correctly,
But when I execute this statement:
SELECT sysdate FROM OracleLinkedServer...dual;
...it gives an error:
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "OraOLEDB.Oracle" for linked server "OracleLinkedServer" reported an error. Provider caused a server fault in an external process.
Msg 7311, Level 16, State 2, Line 1
Cannot obtain the schema rowset "DBSCHEMA_TABLES" for OLE DB provider "OraOLEDB.Oracle" for linked server "OracleLinkedServer". The provider supports the interface, but returns a failure code when it is used.
You should UNCHECKED the Allow inprocess in OraOLEDB.Oracle provider under the Linked Servers node.
