What are some best practices for writing SQLScript for use with calculation views?

Best practices for writing SQLScript in calculation views include:

A. Break up large statements by using variables: This makes the script easier to read, maintain, and debug.

D. Choose declarative language instead of imperative language: Declarative SQL is more efficient and optimized for database processing in SAP HANA.

Dynamic SQL (B) and control flow logic (C) are discouraged due to potential performance and maintenance issues.
