Apache Cassandra 1.1 Documentation
USE¶
Connects the current client session to a keyspace.
Synopsis¶
USE <keyspace_name>;
Description¶
A USE statement tells the current client session and the connected Cassandra instance which keyspace you will be working in. All subsequent operations on column families and indexes are in the context of the named keyspace, unless otherwise specified or until the client connection is terminated or another USE statement is issued.
Example¶
