> I guess you need to clarify the issue first in JIRA. > implementation looks weird before that. Thanks for review. If a sql `insert into emps select * from emps` visited by SqlShuttle, and then `System.out.println(sqlNodeVisited.toString());` it will throw a UnsupportedOperationException,because it has not yet been implemented.We can see the [SqlSyntax#SPECIAL](https://github.com/apache/calcite/blob/bd1fbfe3c062af0879f36ad0e8b53cb0aaec3842/core/src/main/java/org/apache/calcite/sql/SqlSyntax.java#L113) here. There is a case that can be reproduced in [JIRA](https://issues.apache.org/jira/browse/CALCITE-4022), I hope it can be explained clearly. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
