> cqlsh complains when you try to do UPDATE with counter columns
> --------------------------------------------------------------

> Key: CASSANDRA-3493

> 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.
