EnablingDebug Query modein a calculation view allows you to:

Identify data sources that are not accessed by a query: This helps in debugging and optimizing the calculation view by showing which nodes or sources are unnecessary for a specific query.

In a flowgraph, the data source node supports various types of objects for flexibility in data integration:

A. Virtual table: Enables access to remote data sources via Smart Data Access (SDA).

B. Calculation view: Allows using pre-aggregated or calculated data as a source.

D. Synonym: Serves as an alias for database objects, simplifying access to objects across schemas.

Procedures (C) and table functions (E) are not directly used as data sources in flowgraphs.

Acalculation view properties filecontains descriptions of all objects defined in the calculation view, such as attributes, measures, joins, and dependencies. This file serves as metadata documentation for understanding the view structure and dependencies.

Ananonymous blockin SQLScript allows you to test your code without generating a persistent logic container (such as a procedure or function). This is particularly useful for quickly validating or debugging SQLScript logic in a temporary execution context.

When a design-time file of a calculation view is deleted, the corresponding runtime object (thedatabase view) is not automatically removed. To ensure that it is also removed from the database, you mustbuild the projectthat contained the deleted design-time file. This triggers the HDI container to synchronize the runtime objects with the current state of the design-time artifacts.

The block must start with a node that defines a table as a data source (C):Parallelization blocks are designed to work with table-based nodes as starting points for splitting workloads.

Only one block can be defined across a stack of calculation views (D):This restriction ensures consistency and avoids conflicts during parallel execution.

Acalculation view query snapshotis arecord of the query statement executedon a calculation view. It captures the SQL query or execution details for analysis or troubleshooting purposes.

The "Ignore multiple outputs for filters" property in a calculation view ensures that filters are applied consistently and correctly at thelowest node. This setting forces filters to be applied as early as possible in the data flow, ensuring that redundant or incorrect data processing does not occur at higher nodes. This improves performance and maintains the integrity of the filter logic.

Unfolding is a query optimization technique where parts of a calculation view are translated into SQL. Consequences include:

Count-distinct results are incorrect (B):The unfolding process may not preserve distinct counting logic correctly, potentially leading to inaccuracies.

SQL compilation time increases (C):The complexity of unfolded SQL queries can lead to longer compilation times due to the intricate relationships and data structures involved.

Option A is incorrect because unfolding does not relate to static caching, and D is partially correct but not as significant as B and C.

The credentials clause defines TYPE 'PASSWORD' but does not specify a technical user (A):The technical user must be provided when TYPE 'PASSWORD' is used for authentication.

The specified adapter is not registered with your SAP HANA system (D):The adapter must be properly registered and available in the SAP HANA system to establish a remote source connection.

Options B and C are incorrect as network reachability issues are not related to the SQL statement syntax, and the CREATE REMOTE SOURCE privilege must exist on the SAP HANA system, not the remote system.
