Subject [jira] [Updated] (CASSANDRA-3068) Fix count()
Date Wed, 07 Sep 2011 14:12:10 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-3068?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Ellis updated CASSANDRA-3068:
--------------------------------------

    Attachment: 3068-v2.txt

v2 attached to fix above problems.

I also noticed that SQL count(expression) is defined as "the number of input rows for which
the value of expression is not null," with count(*) special cased as "the number of input
rows."

I don't think we want to try to support count(expression) for now, can we restrict the grammar
to count(*), and possibly count(1) since that is also frequently used by Oracle veterans?
