Subject Re: Calcite Question for you
Date Thu, 25 Jun 2020 02:10:30 GMT
Hi Ted, 
That probably would solve the issue for the user. However what's happening is that certain
JDBC DBs (Oracle) are returning data types that Drill does not support and the queries are
failing with a validation error.  IMHO, there should be some way to either tell Drill that
this weird field is a specific datatype or something so that the user can access the data.
It seemed as if Vova proposed a solution to Calcite but it was never adopted.  I'm wondering
if there's some way that we can either extend that class, or somehow catch the exception which
is being thrown and fix the issue. 
Best,
