How to make an ArcGIS Pro one-to-many table join?

Question

From what I have been able to find in the ArcGIS Pro documentation via Google search for one-to-many table joins the only method other than using python (which I am not great at) would be the Query Table tool.

When I use the Query Table tool the output generates a temporary polygon feature class but whenever I try and view the attribute table it ends up with a spinning circle of doom and never loads. There is no error code associated so I'm not sure how to hunt down the problem.

Does anyone know how I might trouble-shoot this issue or if there is another way to do a one-to-many join in ArcGIS Pro?

Answer 1

I'm not sure why the Query Table never seemed to work for me. It seemingly never went beyond a 2% completion even after I cleaned up the data to reduce the number of columns and/or rows. What I was able to find, however, was a round-about method which appears to work even though in the onset it doesn't (weird, right?).

Here is the link to that round-about method I used

While the above link seemingly solved my problem it didn't utilize the known ArcGIS Pro one-to-many options, so, to keep with the spirit of the original question, if anyone else could answer on it, that would be wonderful.
