Subject [jira] Commented: (HIVE-972) support views
Date Wed, 23 Dec 2009 03:05:29 GMT

    [ https://issues.apache.org/jira/browse/HIVE-972?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12793908#action_12793908

John Sichi commented on HIVE-972:
---------------------------------

Namit, alter view <viewname> compile is a good solution to the select * problem, since
assuming we save the original view definition untouched (in addition to the expanded one),
we can re-expand the *'s at that time.  So a user will only have to recompile a view by name
to see the new columns (without having to know its definition).

Regarding error messages, I'll think about what can be done.  In general, AST rewrites make
reporting parse positions difficult, but maybe we can do it with respect to the view subtree
and provide that SQL in the error message as context.
