Not all relations are allowed in a query. For instance, non-equal relations (where @IN@ is considered as an equal relation) on a partition key is only supported if the partitioner for the keyspace is an ordered one. Moreover, for a given partition key, the clustering keys induce an ordering of rows and relations on them is restricted to the relations that allow to select a *contiguous* (for the ordering) set of rows. For instance, given

The @ORDER BY@ option allows to select the order of the returned results. It takes as argument a list of column names along with the order for the column (@ASC@ for ascendant and @DESC@ for descendant, omitting the order being equivalent to @ASC@). Currently the possible orderings are limited (which depends on the table "@CLUSTERING ORDER@":#createTableOptions):
