To answer this question, you need to understand the concept of server-side procedures. Let's go through each option to understand why it is correct or incorrect:
Option A) When the procedure contains no SQL statements.
This option is incorrect because server-side procedures often contain SQL statements to interact with the database.
Option B) When the procedure contains no PL/SQL commands.
This option is incorrect because PL/SQL is a programming language used for writing server-side procedures. Therefore, a server-side procedure would typically contain PL/SQL commands.
Option C) When the procedure needs to be used by many client applications accessing several remote databases.
This option is incorrect because the situation described here relates to a distributed database environment, where multiple remote databases are accessed by client applications. In this case, you would create a distributed database architecture, not necessarily a server-side procedure.
Option D) When the procedure needs to be used by many users accessing the same schema objects on a local database.
This option is correct because a server-side procedure is typically created when multiple users need to access the same schema objects on a local database. In this scenario, a server-side procedure provides a centralized and efficient way to manage and execute common tasks or operations.
The correct answer is Option D. This option is correct because it accurately describes the situation where you would create a server-side procedure.
