User DSN is stored in the Windows Registry under HKEY_CURRENT_USER.įile DSN is stored in a text file with a. ![]() Hence, only the user who created the User DSN is able to use and connect to the target data source using the User DSN. User DSN is a user-specific DSN that is visible only to the user who created the DSN. System DSN is stored in the Windows Registry under HKEY_LOCAL_MACHINE. System DSN is used throughout the system such that anyone with proper rights may log in to access the DSN, and must be created on the machine where the SQL Server database program is located. There are 3 types of DSN that can be created on the ODBC Data Source applet: It stores the connection details such as the database name, directory, database driver, User ID, password etc. What is a Data Source Name (DSN)?Ī Data Source Name (DSN) is a symbolic name that represents a connection to an ODBC Data Source. On the same machine that is hosting the target SQL Server database (in my case, the Windows Server 2019 VM), I created a DSN for the target data source using ODBC Data Source Administrator applet. Step 1: Create a DSN for the target data source In the setup I'm using for the data pipeline simulation, the Microsoft SQL Server is hosted remotely on a Windows Server 2019 Virtual Machine (VM). Before we can access a database in Microsoft SQL Server, we need to configure a Data Source Name (DSN) for the data source (database/server) with the ODBC driver on the native machine hosting the target SQL Server database. When writing programs that involve interacting with a database, we need to use connection modules or client drivers to establish a database connection in order to send commands and receive responses in the form of a result set.Ĭonnecting to Microsoft SQL Server from a Python program requires the use of ODBC driver as a native data access API.
