[jira] [Commented] (IGNITE-7664) SQL: throw sane exception on unsupported SQL statements

    [ https://issues.apache.org/jira/browse/IGNITE-7664?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16769390#comment-16769390 ] 

Vladimir Ozerov commented on IGNITE-7664:
-----------------------------------------

What we need is to investigate H2 syntax of SELECT and DML statements, and list unsupported features (e.g. recursive WITH). Once the list is ready, we need to make sure that proper error messages are thrown during parsing.
