Error with Oracle

Start by reproducing the issue with the Oracle Docker image and the linked gist. Inspect FSharp.Data.Sql.SqlDataProvider, SqlTypeProvider, and the reported GetProperties/get_Col failure to identify the Oracle schema that triggers duplicate members. Done means the same simple query compiles without the provided-type exception, with a regression test if the repository has an applicable test location.

Description

When doing simple queries on some oracle tables, the TP raises an exception

Repro steps

1. Use Oracle Docker Image

2. Use the following gist as a project: https://gist.github.com/imetallica/0dff42841a7273c61fd7149ea0e42e8d

Actual behavior

This is the exception it raises
