Which Node.js module do you use to run an SQL statement against the SAP HANA database? Please choose the correct answer.
Correct Answer: D
To run an SQL statement against the SAP HANA database from a Node.js application, you need to use the
@sap/hdbext module. This module provides a wrapper for the SAP HANA client for Node.js, which enables you to connect to the SAP HANA database and execute SQL statements. You can use this module to create a database connection pool, execute queries, fetch results, and handle errors. The other options are not correct because:
* A. @sap/hdi: This module provides functions to interact with the SAP HANA Deployment
* Infrastructure (HDI), which enables you to create and manage database artifacts, such as tables, views, procedures, and functions, using the HDI container service. You can use this module to deploy, undeploy, and access HDI containers, but not to run SQL statements against the SAP HANA database.
* B. @sap/xsenv: This module provides functions to load service configuration and credentials from the environment variables of the SAP Cloud Platform or the SAP HANA XS Advanced Model. You can use this module to access the SAP HANA database service information, such as host, port, user, password, and schema, but not to run SQL statements against the SAP HANA database.
* C. @sap/xssec: This module provides functions to handle authentication and authorization for Node.js applications using the User Account and Authentication (UAA) service and the XSUAA service. You can use this module to verify JWT tokens, check scopes, and obtain user information, but not to run SQL statements against the SAP HANA database.
