Oracle与SQL Server的数据库连接

Software:

SQL Server 2005 (win 2003) Oracle 10gR2 (Redhat AS 4 update 2) 1. isntall 10201_client_win32.zip under D:\oracle if the D: drive is NTFS you have to give ALL rights to the user 2. listener.ora and tnsnames.ora $ e /u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora ...... ...... ...... ...... ...... ...... ......

DB_Link in SQL ServerIn General Tab

Link_ Name: Other Data Source Link: Microsoft OLE DB Provider for Oracle Product name: Oracle Data_ Source: the Name in ODBC Link_Ora (step 3) User ID=username;Password=userpasswd or UID=username;PWD=userpasswd (the username / password in Oracle)

In Security Tab:

Select the last option: enter the username / password in Oracle

Or to use SQL:

ADD: EXEC sp_addlinkedserver 'Link_Ora', 'Oracle', 'Link_Ora ', 'Server name or IP' EXEC sp_addlinkedserver 'Link_Ora', 'Oracle', 'Link_Ora ', 'ETMCDB' EXEC sp_addlinkedsrvlogin @rmtsrvname='Link_Ora',@useself='false',@locallogin='sa',@rmtuser='sys',@rmtpassword='oracle'or 'Link_Ora','false',null,'rmtuser','rmtpassword' DEL: IF EXISTS (SELECT srvname FROM master.dbo.sysservers srv WHERE srvid != 0 AND srvname = N'DB_Link_Name') EXEC master.dbo.sp_dropserver @server=N'DB_Link_Name', @droplogins='droplogins'

Testing:

SELECT * FROM Link_Ora .ERP.BAS_ITEM_CLASS SELECT * FROM openquery(OraTest,'SELECT * FROM OraTest.ERP.BAS_ITEM_CLASS ')
