[jira] [Commented] (CALCITE-2353) Allow user to override SqlSetOption in alterStatementParserMethods

    [ https://issues.apache.org/jira/browse/CALCITE-2353?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16502690#comment-16502690 ] 

Shuyi Chen commented on CALCITE-2353:
-------------------------------------

By swapping the order, the parser will match the user DDL rule first, so you can implement your own SET operation, is that what you intend to do?

I am not an expert in the parser logic, but it sounds fine to me.

> If alterStatementParserMethods are added before SqlSetOption then the user can replace SqlSetOption. This change matches how statementParserMethods are added at the top level.
