问题
I'm using SSIS and would like to pull in the public NADAC data from this page using the OData connection: https://data.medicaid.gov/Drug-Pricing-and-Payment/NADAC-National-Average-Drug-Acquisition-Cost-/a4y5-998d.
You can find the OData endpoint on their page by clicking on the ellipse and selecting Access Data via OData. The v4 endpoint is: https://data.medicaid.gov/api/odata/v4/a4y5-998d
In SSIS (Visual Studio 2015, Version 14.0.500.272 targeted at SQL Server 2016), I am able to create an OData Source Connection Manager to the base URL: https://data.medicaid.gov/api/odata/v4/
You can see the test connection succeeded. Note: If I specify the full OData End Point URL here, it does succeed, but then doesn't find any collections to connect to in the next step, which I why I'm not doing that. (The message is "Unable to load collection for the connection OData Source, reason: Cannot open this connection")
Also note, I'm using "Windows Authentication" but this is a public feed and no authentication is required. There doesn't appear to be a "anonymous authentication" option.
The next step is to drag the OData Source onto my data flow and right-click to edit it. When I do this, I first select the OData connection manager I just created. It recognizes the connection and displays a drop-down list of collections I can connect to.
Clearly, I'm doing something right up until this point, since it's recognizing the collections that are available.
However, whether I:
- Select any collection in the list
- Select the collection in the list that I want (a4y5-998d)
- Switch from collection to resource path and paste in the resource path I want (a4y5-998d)
and then click "Preview..." or "Columns" or even "OK" - Visual Studio becomes entirely non-responsive. For 20+ minutes. I have to use Task Manager to crash out and try again. If I let it sit forever, I eventually get a yellow warning message: Pipeline component has returned HRESULT error code 0xC020801F from a method call.
I also haven't had any success with the v2 OData feed endpoint that Medicaid provides (https://data.medicaid.gov/OData.svc/a4y5-998d).
My two questions:
- Am I doing something obviously wrong? Perhaps I'm using the wrong URL, or not setting something correctly?
- Do you experience the same problem or are you able to get it to work using the steps I've tried? To recreate, create a new SSIS package with a Data Flow component and follow my steps.
Note: I am able to bring the data in using Power BI (for example), so I don't think there's anything wrong with the feed. It's just SSIS I'm struggling with.
Thanks in advance for any help.

This was a visual studio bug. I upgraded from SSDT 17.0 to SSDT 17.4 (SSIS version 14.0.1000.169) and the error went away.
