cqlsh complains when you try to do UPDATE with counter columns
--------------------------------------------------------------
Key: CASSANDRA-3493
URL: https://issues.apache.org/jira/browse/CASSANDRA-3493
Project: Cassandra
Issue Type: Bug
Components: Tools
Reporter: paul cannon
Assignee: paul cannon
Priority: Minor
trying to do a counter column UPDATE in cqlsh causes an "Invalid syntax" error:
{noformat}
cqlsh:foo> update brongo SET boo = boo+1 where key='hi';
Invalid syntax at line 1, char 28
update brongo SET boo = boo+1 where key='hi';
^
{noformat}
This is cause cqlsh's lexer doesn't know that + and - are valid operators in
CQL. Don't worry, I'm not trying to make cqlsh be able to parse all CQL with
exactness- it tries, in order to provide the best tab completion, but when it
fails to parse it can still pass on CQL text to the server. This case is
different because it's the lexer that can't understand the operators, before we
even get to the parser. We do need a working and correct lexer, along with at
least minimal parsing capability, in order to reliably split up statements,
tell when the user is changing the keyspace, or SELECTing on a columnfamily
with ASSUMEd types.
Also, the parser should be tweaked in a manner similar to CASSANDRA-3418.
