Abstract
A method, a computer program product and a system are provided. A case expression is analyzed for redundant expressions, patterns equivalent to a built-in function, and specific functions to form a simplified expression, wherein the case expression is written in a language supported by a database management system. The simplified expression is optimized based on a cost benefit evaluation of no optimization, native code generation, hashing inputs, and a results caching algorithm to form an execution plan. The execution plan is utilized in the database management system for the case expression.
