Subject [jira] [Commented] (CASSANDRA-8492) Support "IF NOT EXISTS" for "ALTER TABLE ADD COLUMN"
Date Wed, 20 May 2015 10:18:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8492?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14552096#comment-14552096

Aleksey Yeschenko commented on CASSANDRA-8492:
----------------------------------------------

I'm a bit wary of adding this. It's not crucial, it's not present in Postgres or MySQL, and
it's not mirrored by a matching {{ALTER TABLE DROP COLUMN IF EXISTS}}.
