If you’re using versions of Cassandra prior v1.0 beta one of the above links may be more appropriate as little things may have changed here and there. The official doc is on Gitub in textile markup here https://github.com/apache/cassandra/blob/trunk/doc/cql/CQL.textile

Cassandra Query Language (CQL) v1.0.0 (UPDATED)


NOTE: CQL V2 reference is available here http://crlog.info/2011/09/17/cassandra-query-language-cql-v2-0-reference/

Cassandra Query Language (CQL) v1.0.0

This is an update to my previous post documenting the Cassandra query language CQL. A few changes have been made in CQL, the biggest change being the addition of the INSERT keyword. Previously the UPDATE statement would perform an insert if a value did not already exists, the INSERT statement now explicitly does this inserting. BATCH and ALTER TABLE are also now included in the mix, see the official doc here : https://github.com/apache/cassandra/blob/trunk/doc/cql/CQL.textile.
