Connect to PostgreSQL database from SQL Server Linked Server

Updated: 04 Jan 2023


Progress DataDirect’s PostgreSQL ODBC Driver offers a high-performing, secure and reliable connectivity solution, for ODBC applications to access PostgreSQL data. If you want to connect PostgreSQL data from SSLS, Progress DataDirect has you covered. In this tutorial, you will learn how to configure the DataDirect PostgreSQL driver within SSMS (SQL Server Management Studio). These steps can also be used to configure any ODBC connection. 


SQL Server Management Studio is an ideal environment for managing the infrastructure of the SQL Server database and SQL Server itself. With SSMS, you can easily connect to your SQL Server instance, configure and monitor database objects, as well as execute queries. Besides this, there is a possibility to create an ODBC connection to external data from SSMS.


Thus, you can work with other databases and clouds used by your applications.


In this article, we will describe a step-by-step procedure for establishing a connection to PostgreSQL from SSMS using our ODBC Driver for PostgreSQL
