StreamSQL Guide

StreamSQL is StreamBase's text-based language for writing applications to query streams of data. StreamSQL applications are analogous to graphical EventFlow applications, but are stored in files with an ssql extension.

This guide is primarily a language reference that describes how to use the StreamSQL language elements. For general concepts and primitive operations common to both EventFlow and StreamSQL applications, look for references to appropriate topics in the Authoring Guide.
