Introduction to CQL

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. Use CQL to insert, update, and query tables, plus much more. You can run CQL commands in DataStax Studio. See Using DataStax Developer Studio for Astra databases.

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