Subject [jira] [Commented] (CASSANDRA-4776) Don't require quotes for true and false
Date Thu, 25 Oct 2012 03:38:15 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4776?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13483863#comment-13483863
] 

John Sanda commented on CASSANDRA-4776:
---------------------------------------

Where/how can I access the latest CQL3 docs? I just ran ant generate-cql-html from trunk where
my HEAD is a commit from 10/17. I am not sure how different that is from the doc I cited in
the description.

> The docs at http://cassandra.apache.org/doc/cql3/CQL.html#identifiers describe using
double quotes for an identifier that is a reserved word. The following works as expected,
> cqlsh:test> select "columnfamily" from system.schema_columnfamilies;
> I have a table with a boolean column. In order to insert a boolean value, I have to enclose
it in single quotes. The table looks like,
> CREATE TABLE bool_test (
>   id int PRIMARY KEY,
>   val boolean
> );
> Here is what happens when I try using double quotes,
> cqlsh:rhq> insert into bool_test (id, val) values (4, "false");
> Bad Request: line 1:43 no viable alternative at input 'false'
> The use of single quotes here seems inconsistent with what is described in the docs,
and makes things a bit confusing. It would be nice if single or double quotes could be used
for identifiers that are reserved words. I also think it is a bit counter-intuitive to require
quotes for true and false which are literal values.
