Large procedures are an anti-pattern in procedural programming languages; we need to understand why SQL is different. Large SQL statements create several risks and opportunities; we must be aware of the consequences of parsing, optimizer transformations, resource consumption, context switches, and parallelism. Finally, we need to learn how to read and debug large SQL statements.
