TIBCO BusinessEvents® Event Stream Processing Query Developer's Guide

Software Release 5.3

May 2016

• Important Information
  
• TIBCO Documentation and Support Services
  
• Query Features Overview
  The query language enables you to make queries using an SQL-like language. Queries are executed in query agents. You can query cache content (requires Cache OM), and you can also query events (event stream processing).
• Query Language Components
  The text of a query uses a structure similar to the structure of a SELECT statement in SQL, and it has parallels with the structure of a TIBCO BusinessEvents rule, too. The query text is provided as an argument to the Query.create() function.
• The Query Language Usage
  The query language can be used to create and execute queries, and use results returned by a query.
• Continuous Queries
  A continuous query returns results throughout its lifetime, as changes occur. When nothing changes, the query waits.
• Event Stream Processing (ESP) Queries
  You can configure a query agent to process events arriving through a channel, using continuous queries.
• Query Language Reference
  The syntax diagrams shows the structure of a query and of each clause in a query. Operators and other items are also used in the syntax diagrams to add more clarity to the clauses.
