["Robert Stupp (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-7461?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Robert Stupp resolved CASSANDRA-7461.
-------------------------------------
    Resolution: Won't Fix

Closing as "won't fix" as this would make CQL a "whole" programming language.

>                 Key: CASSANDRA-7461
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7461
>             Project: Cassandra
>          Issue Type: New Feature
>          Components: CQL
>            Reporter: Robert Stupp
>              Labels: cql
>
> Intention: Allow operators in CQL
> Operators could be decimal arithmetics {{+ - * /}} or boolen arithmetics {{| & !}} or string 'arithmetics' {{+}}
> {{SELECT tab.label + ' = ' + tab.value FROM foo.tab}}
> {{SELECT * FROM tab WHERE tab.label + ' = ' + tab.value = 'foo = bar'}}
> as well as
> {{CREATE INDEX idx ON tab ( tab.tabel + '=' + tab.value )}}
> or
> {{CREATE INDEX idx ON tab (label) WHERE contains(tab.tabel, 'very-important-key')}}
> Operators could be mapped to UDFs like this:
> {{+}} mapped to UDF {{cstarstd::oper_plus(...)}}
> {{-}} mapped to UDF {{cstarstd::oper_minus(...)}}
> or handled directly via {{Cql.g}} in 'special' code
