> QueryRecord hits a run time exception when using double quotes
> ---------------------------------------------------------------

> Key: NIFI-4047
> URL: https://issues.apache.org/jira/browse/NIFI-4047
> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Joseph Percivall
> Attachments: NIFI-4047.xml

>
> To reproduce:
> Attempt to run the below query. "first" is a reserved word so it needs to be
> surrounded it in quotes.
> SELECT "first" AS first_seen
> FROM FLOWFILE
> In doing so, the processor successfully validates and is ready to run. When
> run, it hits the following RunTimeException:
> 16:16:31 EDT ERROR 82ec3eda-015c-1000-5f5e-3dbf6d4b3145
> QueryRecord[id=82ec3eda-015c-1000-5f5e-3dbf6d4b3145] Unable to query
> StandardFlowFileRecord[uuid=cd8d94cb-96b4-4daf-96a5-454d4d4640d9,claim=StandardContentClaim
> [resourceClaim=StandardResourceClaim[id=1496946569360-1, container=default,
> section=1], offset=6721, length=167],offset=0,name=22416107244401,size=167]
> due to java.lang.RuntimeException: parse failed: Encountered "\"" at line 1,
> column 8.
> Was expecting one of:
> "UNION" ...
> "INTERSECT" ...
> (where it continues to list all the expected values)
> I think the double quote is somehow getting mis-translated when being parsed
> by the Calcite backend.
