To improve the performance of joins in aCUBE calculation view, the following approaches are recommended:

A. Specify the join cardinality: Defining the cardinality helps the optimizer understand the data relationships and execute the join efficiently.

B. Limit the number of joined columns: Reducing the number of columns involved in the join minimizes data processing overhead, improving query performance.

Using afull outer join(C) or avoiding inner joins (D) are less performance-optimized in most scenarios.

To fine-tune performance (B):Implementing SQL in calculation views can help optimize performance by leveraging advanced SQL features and minimizing unnecessary data movement.

To define dynamic analytic privileges (D):SQL enables the implementation of conditions for dynamic analytic privileges, ensuring fine-grained and context-sensitive data access.

Options A and C are less relevant as SQL is not primarily for expanding consumption possibilities or implementing functions, which are handled by other mechanisms in SAP HANA.

In dynamic SQL analytic privileges, aprocedurereturns the data access condition as an SQL expression. This approach allows for dynamic evaluation of access conditions based on runtime criteria, such as user roles or specific query parameters.
