1. One or more computer storage media having computer-executable instructions embodied thereon that, when executed, by one or more processors, cause the one or more processors to perform a method for generating event processing language code in development environments using event processing compilers, the method comprising: receiving a query in a development environment, wherein the query comprises event processing language code; compiling the query using an event processing compiler, wherein compiling the query transforms the query from the event processing language code to a development environment script language code based at least in part on event processing attributes that are aligned in syntax and semantic between the event processing language code and the development environment script language code, and wherein based on compiling the query, development environment assistance functionality in the development environment of the development environment script language code operates to validate the event processing language code through the development environment script language code; and executing the query as the development environment script language code using sample data, wherein executing the query generates output comprising results data based on the sample data.
