Andrés de la Peña created CASSANDRA-14205:
---------------------------------------------
Summary: ReservedKeywords class is missing some reserved CQL
keywords
Key: CASSANDRA-14205
URL: https://issues.apache.org/jira/browse/CASSANDRA-14205
Project: Cassandra
Issue Type: Bug
Components: CQL
Reporter: Andrés de la Peña
Assignee: Andrés de la Peña
Fix For: 3.11.x, 4.x
The CQL keywords {{DEFAULT}}, {{UNSET}}, {{MBEAN}} and {{MBEANS}} (introduced
by CASSANDRA-11424 and CASSANDRA-10091) are neither considered [unreserved
keywords|https://github.com/apache/cassandra/blob/trunk/src/antlr/Parser.g#L1788-L1846]
by the ANTLR parser, nor included in the
[{{ReservedKeywords}}|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/cql3/ReservedKeywords.java]
class.
The current parser behaviour is considering them as reserved keywords, in the
sense that they can't be used as keyspace/table/column names, which seems right:
{code:java}
cassandra@cqlsh> CREATE KEYSPACE unset WITH replication = {'class':
'SimpleStrategy', 'replication_factor': 1};
SyntaxException: line 1:16 no viable alternative at input 'unset' (CREATE
KEYSPACE [unset]...)
{code}
I think we should keep considering these keywords as reserved and add them to
{{ReservedKeywords}} class.
