Unhandled Exception adding SQL to Input Tool



I am having problems with a Windows 10 installation of Alteryx Designer.

I have a workflow that runs perfectly well on a Windows 7 machine but not on Windows 10.


The problem appears to be with the Input Tool.

I have a reasonably long piece of SQL code which has never caused issues before, but whenever I put it into the windows 10 system I get an unhandled exception error.


If I randomly cut out about half of the code it stops giving the error, but I obviously can't do that as the SQL would make no sense.


I have found an error log which has the following:

Is there some limit imposed somewhere on the length of code and how do I get round this please.


My DB connection is 32bit Oracle OCI

Alteryx version on both machines


Thank you...

I would submit this to Alteryx Support so it can be investigated as a bug.


There is a workaround that I am currently using, and that is to NOT use a database alias at present. Instead I just use a 32bit OCI connection and that seems to be working.

Thank you...
