[jira] Commented: (CASSANDRA-1706) CQL deletes (aka DELETE)

["Jonathan Ellis (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-1706?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12929125#action_12929125 ] 

Jonathan Ellis commented on CASSANDRA-1706:
-------------------------------------------

I think that we should support deleting columns as well as entire rows:

{code:SQL}DELETE <CDL>? FROM <CF> [USING CONSISTENCY.<LVL>] WHERE KEY=<X>|KEY IN <Y>{code}

> CQL specification and implementation for data removal.
> This corresponds to the following RPC methods:
> * remove()
> * batch_mutate() (deleting, not updating)
> * truncate() (?)
> My thoughts on the syntax are that it can probably closely mirror a subset of `SELECT':
> {code:SQL}
> DELETE (FROM)? <CF> [USING CONSISTENCY.<LVL>] WHERE <EXPRESSION>
> {code}
> Optionally, you could support a form that makes the `WHERE' clause optional, statements without the clause would be interpreted as a column family truncation.
