Caleb Rackliffe commented on CASSANDRA-19604:
---------------------------------------------
Was taking a look at this. Is this bit unused in the grammar? (i.e. in
{{Parser.g}})
{noformat}
betweenLiterals returns [Terms.Raw literals]
@init { List<Term.Raw> list = new ArrayList<>(); }
@after { $literals = Terms.Raw.of(list); }
: t1=tupleLiteral { list.add(t1); } K_AND t2=tupleLiteral { list.add(t2); }
;
{noformat}
> Add support for BETWEEN operator
> --------------------------------
>
> Key: CASSANDRA-19604
> URL: https://issues.apache.org/jira/browse/CASSANDRA-19604
> Project: Cassandra
> Issue Type: Improvement
> Components: CQL/Interpreter
> Reporter: Benjamin Lerer
> Assignee: Simon Chess
> Priority: Normal
> Fix For: 5.1
>
> Time Spent: 3h 20m
> Remaining Estimate: 0h
>
> CQL support the {{>=}} and {{<=}} but does not support yet the {{BETWEEN}}
> operator. After CASSANDRA-19341 adding new operators should be much simpler
> and safer than it use to be.
> For the scope of this ticket {{BETWEEN}} support should be added for
> {{WHERE}} clauses of {{SELECT}} and {{DELETE}} queries (for single column and
> multi-column restrictions). NOT BETWEEN should be added and should be
> supported everywhere BETWEEN is.
> +Additional information for newcomers:+
> Parts that will need to be modified:
> * {{Lexer.g}} and {{Parser.g}} to add support for the new keyword and syntax
> * The {{Operator.class}} to add the new {{BETWEEN}} operator
> * Unit tests in {{SelectSingleColumnRelationTest}} and
> {{SelectMultiColumnRelationTest}} classes for the different types of columns
> (partition key, clustering, static and regular).
> * CQLSH auto completion in {{cql3handling.py}} and test for it in
> {{test_cqlsh_completion.py}}
> * Update the documentation
> Of course this is just an overview and some other parts might have to be
> changed as well.
