Creating Oracle Linked Server in SQL Server

I wrote multiple articles on heterogeneous linked server which helped user to connect to Sybase , SQL Server & MySQL RDBMS platforms. However I missed creating Oracle linked server , many users responded to write an article on this so I decided to complete it. As you know when you create a heterogeneous linked server you need proper driver of the destination RDBMS. I have split this into two sections a.) Installing Oracle Driver and configuring tnsnames.ora file b.) Creating Oracle linked server in SQL Server Continue reading Creating Oracle Linked Server in SQL Server

Creating Linked server to SYBASE from SQL Server

In this article we going to look into creating a heterogeneous linked server. i.e. We are going to create a linked server to SYBASE database server from SQL Server environment and then going to query datas from Sybase. First step in heterogeneous linked server is to create a ODBC connection to that RDBMS platform. For creating ODBC connection we need the ODBC drivers for that RDBMS platform. In this case we need Sybase driver in client machine, this is not included in windows so you need to download it from Sybase Website. Lets discuss on this step by step

Creating Linked server to MYSQL from SQL Server

In this article we going to look into creating a heterogeneous linked server. i.e. We are going to create a linked server to MYSQL database server from SQL Server environment and then going to query datas from MYSQL. First step in heterogeneous linked server is to create a ODBC connection to that RDBMS platform. For creating ODBC connection we need the ODBC drivers for that RDBMS platform. In this we need drivers for MYSQL, this is not included in windows you need to download it from MYSQL Website. Lets discuss on this step by step

Linked server is a concept in SQL Server to access external data sources. This external data sources can be Access, Oracle, Excel, SQL Server or almost any other data system that can be accessed by OLE or ODBC.

Where it is used??
A linked server configuration enables SQL Server to execute commands against OLE DB data sources on remote servers, In simple we can say users can retrieve datas from another instance of SQL Server other data sources (Excel, Access, Oracle etc), this may be another named instance or another SQL Server. Linked servers offer the following advantages:
