You must create User-defined functions (UDFs) by embedding the logic in Java. Cassandra does not support a native procedural extension like relational databases. You do not have sequences in Cassandra because they’re not a good fit for a distributed architecture.
You use the USE command to connect to the keyspace or database, like you would in MySQL. Here’s my script that creates Cassandra keyspace, which is more or less a database.

To configure the bound address, use the rpc_address parameter in cassandra.yaml. The cassandra node should be bound to the IP address of your server's network card - it shouldn't be 127.0.0.1 or localhost which is the loopback interface's IP, binding to this will prevent direct remote access. In Cassandra 2.1, which uses the Datastax python driver, the default cqlsh listen port is 9042.
In Cassandra 2.1, the cqlsh utility uses the native protocol. By default, Cassandra 2.0.x and earlier enables Thrift by configuring start_rpc to true in the cassandra.yaml file. In Cassandra 2.0.x, the default cqlsh listen port is 9160 which is defined in cassandra.yaml by the rpc_port parameter. Remote access to Cassandra is via its thrift port for Cassandra 2.0.
