----------------------------------
Summary: Flink SQL does not support block comment before SET command
Key: FLINK-22998
URL:
https://issues.apache.org/jira/browse/FLINK-22998 Project: Flink
Issue Type: Bug
Components: Table SQL / Planner
Affects Versions: 1.14.0
Reporter: Zhiwen Sun
Flink SQL does not support block comment before SET command.
A tiny SQL that produces the bug:
{code:java}
/**
comment
**/
SET sql-client.execution.result-mode=TABLEAU;
SELECT 'hello';{code}
while following SQL works fine:
{code:java}
SET sql-client.execution.result-mode=TABLEAU;
/**
comment
**/
SELECT 'hello';{code}
After I debug Flink source code, I found that EXTENDED_PARSER does not support block comment.
