I recently upgraded from SQL Server 2017 Express to SQL Server 2019 Express and installed Microsoft SQL Server ODBC Driver 18. However, a sqlcmd script to back up all databases, using Ola Hallengren's maintenance solution, still wants to use Microsoft ODBC Driver 17. I uninstalled Microsoft ODBC Driver 17 for SQL Server. Now I am getting the below error when I run the script in a .cmd file via the Windows Task Manager.

Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : Data source name not found and no default driver specified.

How can I get sqlcmd to use the Microsoft SQL Server ODBC Driver 18?

    Did you install the 64 bit version, 32 bit version, or both? Looks like one is missing.

  • If you opens a cmd with administrator rights, th sqlcmd runs?

  • Yes, but it throws the error listed above if Microsoft ODBC Driver 17 for SQL Server is not installed. I want it to run with Microsoft ODBC Driver 18 for SQL Server.

  • SQLCMD requires the driver version mentioned in the error message (Microsoft ODBC Driver 17). As @SeanGallardy mentioned, make sure 32 and 64 bit versions are installed.

The sqlcmd script absolutely will not run Microsoft ODBC Driver 18 for SQL Server. So I am sticking with Microsoft ODBC Driver 17 for SQL Server. So be it.

This is the documentation that specifies the sqlcmd requirements:

sqlcmd utility

This component requires both the built-in Windows Installer 5 and the Microsoft ODBC Driver 17 for SQL Server.
