When creating store procedures and functions which construct allows you to transfer values to and from the calling environment?

  1. Local variables.

  2. Arguments.

  3. Boolean variables.

  4. Substitution variables.


Correct Option: B

AI Explanation

To answer this question, you need to understand the concepts of store procedures and functions.

When creating store procedures and functions, the construct that allows you to transfer values to and from the calling environment is known as "arguments".

Option A) Local variables - Local variables are variables that are declared and used within the scope of the procedure or function itself. They do not allow you to transfer values to and from the calling environment.

Option B) Arguments - Arguments are variables that are passed to a procedure or function when it is called. They allow you to transfer values to and from the calling environment. This is the correct option.

Option C) Boolean variables - Boolean variables are variables that can have a value of either true or false. They do not specifically allow you to transfer values to and from the calling environment.

Option D) Substitution variables - Substitution variables are used in SQL*Plus, a command-line interface for Oracle Database. They are used to substitute values at runtime, but they do not specifically allow you to transfer values to and from the calling environment in store procedures and functions.

Therefore, the correct answer is B) Arguments.
