000-349 · Question #22

Which one of the following statements is correct with regards to cross referencing information in a database?

The correct answer is C. To return the results of the query in the same format as a query specified for a map input card. When cross-referencing a database in a map rule, the query results are returned in the same format as a query defined for a map input card, ensuring consistent type alignment.

Why each option

When cross-referencing a database in a map rule, the query results are returned in the same format as a query defined for a map input card, ensuring consistent type alignment.

ATo execute any SQL statement supported by your database management system in a component

Executing any SQL statement within a component describes component-level database calls and does not characterize the result format behavior that defines cross-referencing.

BTo execute any SQL statement supported by your database management system in a map rule,

While map rules can execute SQL statements, this choice does not accurately describe the defining characteristic of cross-reference query output formatting.

CTo return the results of the query in the same format as a query specified for a map input card,Correct

When using database cross-referencing functions in a map rule, the results are returned in the same format as a query specified for a map input card, ensuring the output structure aligns with the type tree and field mappings already defined for standard map input. This consistent return format allows the map to process the query results without requiring a separate type definition. This behavior distinguishes cross-referencing from other SQL execution methods available in the tool.

DTo execute a SELECT statement when the database table name varies, DBQUERY must be

DBQUERY is used specifically when the database table name varies dynamically, which is a separate feature unrelated to how cross-reference query results are formatted.
