Benjamin Lerer commented on CASSANDRA-7461:
-------------------------------------------
It is good that you mentioned it. :-)
I have added support for parenthesis in the patch I am currently working on but
I did not think about testing {{((someType)?).bar}}.
> operator functionality in CQL
> -----------------------------
>
> Key: CASSANDRA-7461
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7461
> Project: Cassandra
> Issue Type: New Feature
> Components: CQL
> Reporter: Robert Stupp
> Assignee: Benjamin Lerer
> 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
