In which PROC would you push processing into an Oracle database?

The choice of PROC FEDSQL is correct for pushing processing into an Oracle database because it is specifically designed to execute SQL queries directly against databases, including Oracle, while leveraging the capabilities of those databases for processing. This procedure allows users to write SQL queries that can be executed on remote database systems, which minimizes the amount of data transferred and enhances performance by executing the logic directly on the server.

In contrast, PROC SQL also allows interfacing with databases and executing SQL queries, but it generally operates within the SAS environment itself. Although you can perform operations like connecting to a database and running queries, PROC SQL may not fully utilize the performance advantages that come from executing processing within the Oracle environment.

PROC IMPORT and PROC EXPORT are used for data transfer operations—importing data from an external source into a SAS dataset and exporting a SAS dataset to an external format, respectively. These procedures do not focus on executing queries or pushing processing to a database, making them unsuitable for the specific need to push processing into an Oracle database.
