Accessing Denodo Views through Alteryx

I am trying accessing denodo views through Alteryx. I did setup ODBC connection. I could see the views, but the columns under each view are not getting displayed. Is this a known issue or any setting issue. Thanks in advance.

Hi @pkotapati,

 

This is not one of the currently supported Alteryx data sources (https://www.alteryx.com/techspecs) .  This means that the Alteryx team has not tested and validated the product with their odbc driver.

 

If you would like to request support for Denodo in a future release please head over to our ideas page

I am having issues connecting to Denodo using ODBC connection. Need your support with in an error.

 

Right now, I am able to connect to denodo source and can see the views. However all the views don't have any columns under it. Its all showing as empty.

@pkotapati I am not sure why you aren't able to see the views from Denodo. I just created a sample crm view and I am able to see it using the odbc connection. This could be a permissions issue. I do agree with @JessicaS that this is not one of the currently supported Alteryx data sources (https://www.alteryx.com/techspecs). See below, hope this helps.Alteryx ViewAlteryx View

Create the following empty materialized table in the Denodo vdb that you're connecting to:

 

CREATE OR REPLACE MATERIALIZED TABLE pg_type (
oid:int,
typname:text
);

Back then there's an issue with connection. It is resolved. Thanks.

I am using Alteryx 2019.1

 

Trying to Connect Denodo 7.0

 

Getting the error:

 

could not connect to the server.Connection timed out.

is the server running on host <ip address>  and accepting TCP/IP connections on port 9996?

 

 

Please help if anyone have any idea how to resolve this. The <ip address> can be pinged fine from the Alteryx server.  And  <ip address> is  a unix box hosting Denodo 7.0 server.

Thank you for the suggestion @dzavorotny, I gave it a shot, but I'm still unable to pull any camelCase columns.  The one thing I did notice is that I can see the camelCase columns in Alteryx; however, I am still unable to utilize any of the columns.  When I use the checkbox to select "oId" or "typName" for example I get "No Columns Returned".  Is the expectation that if a materialized view exists in a VDB then it will allow for Alteryx to pull camelCase columns?  How are you using Alteryx to pull camelCase columns?  Does it matter if the view is also in camelCase?  The only workaround we've found so far is to use the SQL Editor and placing double quotes around the field names.  This can get pretty monotonous with some of our bigger views!  Thanks again!

 

@pkotapati - did you ever find a workaround for camelCase columns?
