Is it an intended feature to force the installation of only one version of the msodbcsql package on the system?

Hi erbenfr

This issue originated when support for RHEL7 was discontinued in the driver and we moved the RedHat build to RHEL8. RHEL 7's rpmbuild was more lenient about directory ownership conflicts - it allowed multiple packages to claim ownership of the same directory as long as permissions matched. Our team is actively working on a solution, which is scheduled to be included in the next release planned for February 2026. For a workaround, see: https://github.com/microsoft/linux-package-repositories/issues/299#issuecomment-3750325264

Hi DavidEngelMS ,
Hope you are doing fine!.

I would like to know more about the installation of Security Update for the Microsoft ODBC Driver for SQL Server.

Let us say, I need to install the KB (KB5037571) and I am using Microsoft catalog for downloading the binaries. However, I see many binaries for this KB, as shown in the image below, and I am unsure whether I need to install all of them or just one of them. Any help would be welcome.

Thanks.

Our application breaks using the newest driver. See bug report here:
https://developercommunity.visualstudio.com/t/BCP-Problem-since-MSODBCDriver-18611/11020857

Unfortunately some of our customers are using windows auto updates for those drivers, and it broke some production environments.. just days before the holidays...

  I see the repro is for Windows. 18.6.1.1 wasn't released to Microsoft Update, so there shouldn't have been any auto-update mechanism on Windows in play there, unless it's something the customers initiated themselves. Regardless, though, if there is a bug there, we'll need to fix it. Thanks for the heads up.
