Determine the order of CCL project elements based on clause and statement syntax definitions and limitations.
Define CCL elements that are referenced by other statements or clauses before using those statements and clauses. Failure to do so causes compilation errors.
For example, define a schema using a CREATE SCHEMA statement before a CCL CREATE STREAM statement references that schema by name. Similarly, declare parameters and variables in a declare block before any CCL statements or clauses reference those parameters or variables.
You cannot reorder subclause elements within CCL statements or clauses.
