问题
I tried to create a Dataflow job using the Dataflow SQL UI. I followed the Using Dataflow SQL Tutorial and the job ran properly. I changed the data source to a BigQuery table. My plan is:
- Query from the BigQuery table
- Save the result back to a BigQuery Table.
When I creating the dataflow job, I got the error message: Error in SQL Launcer
What does the error mean? Thanks for your help!

Dataflow SQL does not yet support the DATE type (there was a bug in the SQL Validator that didn't catch that). Selecting a field with DATE type will cause that NPE error message, and the fix is to only select fields that are supported.
