some cases it can be handy if you can query a database from one database server to the other and copy data and tables. Now the fun part is, we can use this on different databases as well, like Oracle, MySql e.g. how cool is that! Let's set up a linked server to Oracle. If you don't have oracle available, you can download and install the Oracle Express edition, which we can get for free from the Oracle site.

After you have succesfully installed Oracle server, fire up MSSQL. First we are going to create a new database for this Linked Server Project, let's call it the ‘FunFactory' a http://www.thebuttonfactory.nl/?p=1047 great program from the '80. Insert some tables and rows and we're done! Now we open the Server Objects in the Object Explorer and right click ‘add new linked server': Now it's very important to fill in the right credentials: You need to connect Oracle on it's TNS name, for example, Oracle Express the default is XE, now press ‘script from', to see the script that will execute when you press ok. Ok, enought with the boring GUI, we are going to create another linked server, but this time we script it: DECLARE @vcLinkedServer VARCHAR(255)

When Creating a Linked Server in SQL Server CA400WIN; OLEDB; server; SQL Technote (troubleshooting) Problem(Abstract) This document describes a resolution to an "Error 7302 Could not create an instance of OLE DB provider http://www-01.ibm.com/support/docview.wss?uid=nas8N1014412 IBMDASQL" being received when attempting to create a linked server in SQL Server. Resolving the problem This document describes a resolution to an "Error 7302 Could not create an instance of OLE DB provider IBMDASQL" being received when attempting to create a linked server in SQL Server. Resolution When using Microsoft SQL Server and distributed queries with the IBM OLE DB Providers supplied with iSeries Access for Windows, the AllowInProcess option must be enabled. ms sql This option is required because SQL Server passes the proper authentication across the remote procedure call only when the OLE DB Provider is configured for AllowInProcess (Microsoft Corporation 2007). Allow InProcess SQL Server allows the OLE DB provider to be instantiated as an in-process server. The default behavior is to instantiate the OLE DB provider outside the SQL Server process. Instantiating the provider outside the SQL Server process protects the SQL Server process from errors ms sql error in the OLE DB provider. SQL Server requires an in-process server for handling specific types of data including long columns, text, and image data. The OLE DB Provider for DB2 does not currently support the DB2 Large Object (LOB) types. This option may be enabled or disabled for the OLE DB Provider for DB2; however, this option is normally unnecessary when using SQL Server 2000." (Microsoft Corporation 2007) Setting the Allow InProcess Provider Option SQL Server 2000 When creating a new linked server (under Microsoft SQL Servers -> SQL Server Group -> [SQL Server Database] -> Security -> Linked Servers -> Right-click on Linked Servers, and select New Linked Server), select the Provider Options button below the OLE DB provider name. Check the Allow InProcess option to enable the property. SQL Server 2005 The Allow InProcess option must be set on the specific provider before the linked server is created. You can add the linked server provider option under [SQL Server Database] -> Server Objects -> Linked Servers -> Providers -> Right-click on a provider, and select Properties. Finally, check the Allow InProcess option to enable the property. References "Distributed Query Support Using the OLE DB Provider for DB2." 2007.
