Introduction to CQL commands 

Shows the CQL command syntax and rules, and provides instruction on using CQL shell (cqlsh).

CQL is the primary language for managing database resources, such as keyspaces, tables, functions, aggregates, user defined types, roles, and access permissions, and insert, update, and query tables, run DSE Search commands, plus much more. You can run CQL commands in DataStax Studio, see Creating a table [in DSE Studio] using CQL.

For production, DataStax supplies a number of drivers so that CQL statements and search commands can be passed from client to cluster and back. Other administrative tasks can be accomplished using OpsCenter.
