Preface

This reference contains a complete description of the Oracle Continuous Query Language (Oracle CQL), a query language based on SQL with added constructs that support streaming data. Using Oracle CQL, you can express queries on data streams to perform event processing using Oracle Event Processing. Oracle CQL is a new technology but it is based on a subset of SQL99.

Audience

This document is intended for all users of Oracle CQL.
