AnInner Joinsupports temporal conditions in SAP HANA calculation views. Temporal conditions involve filtering data based on time-based attributes, such as effective dates or validity periods. Inner joins are capable of including such conditions directly in the join logic to ensure that only matching records based on the temporal criteria are included in the results.

CREATE VIRTUAL TABLE on the remote source (B):This privilege allows the creation of virtual tables that reference remote tables in the target schema.

CREATE ANY on the target schema (C):This privilege ensures that virtual tables can be created in the specified target schema.

Option A (SELECT on the source object) and D (ALTER on the remote source) are not sufficient or required for creating a virtual table.

To view data for the United States when querying aCUBE calculation view, the user must have:

SELECT privilege on the CUBE calculation view: To execute queries on the view.

Analytic Privilege (Country United States) on the DIMENSION calculation view: This restricts access based on the country dimension to only "United States" data.

Analytic privileges must be defined appropriately on both views to enforce the required data access.

To expose a hierarchy to SQL, the following conditions must be met:

B. The hierarchy must be a shared hierarchy: This ensures the hierarchy is reusable and can be consumed in other scenarios.

D. The hierarchy must be exposed by a CUBE calculation view with a star join: Only a cube view with a star join supports SQL exposure for hierarchies.

Local hierarchies and those defined in non-cube calculation views are not SQL-exposed.

Partition large tables (B):Partitioning tables allows for parallel processing of data subsets, significantly improving query execution times.

Limit the number of stacked calculation views (C):Reducing layers of calculation views minimizes complexity and execution overhead, leading to better performance.

Options A and D are incorrect or less effective. Union pruning should be enabled to improve performance, and while aggregating data early can sometimes be beneficial, it is not universally optimal for performance tuning.

When creating a calculation view that accesses a table in an external schema:

A. Synonym: Synonyms act as aliases to access external schema objects. They are required to integrate external tables into the calculation view.

D. Authorization: You need appropriate schema authorizations to access the external table through the synonym.

A remote source (B) is used for accessing remote systems, and an SQL view (C) is not necessary for this scenario.

To identify companies that sold products in both January and February, anIntersect Nodeis optimal. It compares two datasets and retrieves only the records that exist in both. In this scenario, the intersect node ensures that only companies with sales in both months are included in the output.

Aleft outer join nodebetween table A and table B is used to identify products that appear only in table A. The left outer join retrieves all records from table A and matches them with table B, including records that have no corresponding match in table B. By filtering out the rows where table B columns are not null, you effectively isolate products exclusive to table A.

A restricted measure in SAP HANA is a measure that is filtered based on specific attribute values. This allows for focused analytics by calculating measures only for particular segments of data. For example, sales figures for a specific region or product category can be defined as restricted measures, enabling precise analysis within predefined data scopes.

Table functions in SAP HANA are used for read-only operations and cannot includeDML (Data Manipulation Language)statements such asDELETE,INSERT, orUPDATE.

C. Your table function includes a DELETE statement: This is the reason for the deployment failure, as DML operations are not allowed in table functions.

Input parameters (A), table types (B), and references to scalar functions (D) do not cause deployment issues unless they are incorrectly defined, which is not the case here.
