Microsoft OLE DB Provider for DB2You sometime have to deal with ODBC Data Source.

You don’t want to, but you have to.

I’m currently finalizing a post about PolyBase, that typical blog post that takes 4 days instead of 4 hours to be over.

And it turns out I have to install an ODBC connector.

This scares me a bit because I was expecting PolyBase to be a replacement for Linked Server while instead Linked Server looks like the scaffolding at the very base of it.

But let’s not procrastinate and see how to set it up.

Download and Install

You need to download and install Microsoft OLE DB Provider for DB2 from the official link.

Once downloaded you can install it as a normal executable.

Setup

Once installed you can search for Data Access Tool on your computer.
