How to use SQL Analyzer with the Oracle Provider for OLE DB and SQL Server 2000 
  The purpose of this document is to show the steps needed to use the Microsoft SQL Analyzer query tool, which comes with Microsoft SQL Server, with the Oracle Provider for OLE DB. This will enable the user to use the 4 part query naming convention in SQL Analyzer.   
  This note is intended for all audiences that have some knowledge of SQL Analyzer, Oracle Provider for OLE and Microsoft SQL Server.   How to use Microsoft SQL Analyzer with the Oracle Provider for OLE DB
  Microsoft SQL Server 2000 SP 1 or 2
  Microsoft Windows 2000 Server SP 2
  Oracle Provider for OLE DB
  Oracle Client
  Oracle Database
  Instructions to Setup the Linked Server Connection:
  1. Open SQL Server Enterprise Manager 
  2. Click on the + to expand the tree for the database server.  
      You will need to expand it three times.    
      Note: If the SQL Server does not appear here, you will need to right click and go through the Wizard  for SQL Server Registration.  
               - The first level of the tree is called Microsoft Sql Server,
                 The second level of the tree is called SQL Server Group,
                 and the third level of the tree is your SQL Server Database.
                 For these instructions we will call our SQL Server Database,     'Scott'. 
  3. Under the Scott Database, click on the + to expand the tree control     for 'Security' 
  4. Under Security, right click on Linked Servers and select     "New Linked Server" 
  5. In the Linked Server Properties do the following: 
    a. Type in a Linked Server Name, for this example we will call it   'Tiger' 
    b. Under Server Type select Other data source 
       - For the provider name select Oracle Provider for OLE DB. 
    c. In the Data Source field, type in the Oracle Service name (SQL Net Alias) 
    d. Leave the Product Name and Provider String blank.   
    e. Click on the Provider Options button.
       - Check the check boxes for "Dynamic 
         Parameters" and "Allow InProcess"   
    f. Click Apply & then click OK. - The Provider Options dialog closes. 
  6. Go to the "Security" tab in the Linked Server Properties.   
    a. Select the radio button "Be made using this security context" at the bottom of the box.   
    b. Type in the User ID (your Oracle login), ie. Scott in the   "Remote login" field and your Password, ie. Tiger in the       "With Password" field. 
  7. Go to the "Server Options" tab in the Linked Server Properties.   
    a. While leaving the default selections selected, also check the checkbox for "Collation Compatible".   
    b. Click OK This will create your Linked Server named Tiger. 
  Test the Linked Connection 
  To test the Linked Server, open up Microsoft Query Analyzer   (It is found under the Microsoft SQL Server menu option). 
  1. Select your SQL Server in the Connect to SQL Server box.   
    a. Since we have the SQL Server installed on the same machine, we select (local).   
    b. Select the appropriate Connect using option. This is determined when you     
      Installed/Created your SQL Server database. For our example here we use     
      Windows Authentication. And click on the Ok button. 
  2. In the Query screen you can type a query.
      The query will follow this format:
        SELECT * FROM ...   
  3. If you have the default scott/tiger schema installed in your Oracle database you can use the following query:          SELECT * FROM TIGER..SCOTT.EMP 
  4. Type it into the Query box. 
  5. Click on the Green Arrow to run the query. 
  6. You should see the contents of the Emp table in the Grid.
