Subject [jira] [Commented] (CASSANDRA-2474) CQL support for compound columns
Date Sun, 04 Sep 2011 18:11:10 GMT


Rick Shaw commented on CASSANDRA-2474:

The keyword "AS" may be a bit confusing to SQL users. It is a optional keyword that signifies
that that the following word is to be taken has an alias for the first word. In CQL context
it would more appropriately be used for giving a text label to a numeric (or whatever) column
name. I readily admit I do not really understand how this feature works. Even if it is used,
it would seem you would declare it in the reverse order? Like:

SELECT column_name AS alias FROM CF;

Could "WITH" be a substitute for "AS" in this compound context?

> For the most part, this boils down to supporting the specification of compound column
names (the CQL syntax is colon-delimted terms), and then teaching the decoders (drivers) to
create structures from the results.
