Using CCL

More About Sybase CEP Components
A closer look at Sybase CEP components including time, data streams, windows, schemas, datatypes, adapters and query modules. You will need a basic understanding of these components to begin working with CCL queries.
CCL Queries
The Sybase CEP Continuous Computation Language (CCL) is a language based on the ANSI SQL Standard (1998). It is used to manipulate, analyze and process data within the Sybase CEP Engine.
Using Windows
This chapter teaches you how to create basic CCL windows and use them in queries. Windows permit you to maintain the state of rows that have been previously processed from a stream.
Joining Data Sources
A query may use data from multiple data sources, though it must always publish data to a single data source. Using multiple data sources in a single query is handled by an operation called a join.
Controlling Output Timing
Use ouput clauses to delay or regulate the processing of output from a query.
Finding Patterns In Data
Continuous Computational Language (CCL) queries can use a special pattern matching syntax that enables a query to detect the occurrence of certain patterns of events.
Accessing External Databases
Sybase CEP Engine can communicate with external data sources via input and output adapters.
