Scenario: A developer is designing a complex reporting system in DB2 and needs to perform custom calculations on the data. How can user-defined functions assist in this scenario?
- User-defined functions can automatically optimize SQL queries, reducing execution time.
- User-defined functions can encapsulate complex calculations, making them reusable across queries.
- User-defined functions can only be used within stored procedures, limiting their usefulness in this scenario.
- User-defined functions can replace built-in functions, improving performance and scalability.
User-defined functions in DB2 enable developers to encapsulate complex calculations into reusable components. This promotes code reuse, simplifies maintenance, and enhances readability. These functions can be easily integrated into SQL queries, allowing developers to perform custom calculations efficiently within the reporting system.
