Which of the following do not help you execute multiple PL/SQL programs simultaneously?

  1. Oracle Advanced Queuing

  2. DBMS_JOB

  3. DBMS_SQL

  4. Pipelined Functions
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

DBMS_SQL is a package for dynamic SQL operations within a single session - it parses and executes SQL statements sequentially. Oracle Advanced Queuing, DBMS_JOB, and Pipelined Functions all support concurrent/parallel execution of multiple programs through queuing, job scheduling, and parallel query pipelining respectively.

AI explanation

To answer this question, you need to understand the features and capabilities of different PL/SQL execution methods. Let's go through each option to understand why it does or does not help in executing multiple PL/SQL programs simultaneously.

Option A) Oracle Advanced Queuing - This option is incorrect because Oracle Advanced Queuing allows you to enqueue and dequeue messages, which can be used to execute PL/SQL programs asynchronously and in parallel. This feature enables multiple PL/SQL programs to be executed simultaneously.

Option B) DBMS_JOB - This option is incorrect because the DBMS_JOB package allows you to schedule and run PL/SQL programs as jobs. These jobs can be run concurrently, allowing for the execution of multiple PL/SQL programs simultaneously.

Option C) DBMS_SQL - This option is correct because the DBMS_SQL package is used for dynamic SQL execution. While it provides a way to execute SQL statements dynamically, it does not provide a direct mechanism for executing multiple PL/SQL programs simultaneously.

Option D) Pipelined Functions - This option is incorrect because pipelined functions allow you to process data in a streaming manner, which can be beneficial for executing multiple PL/SQL programs simultaneously. Pipelined functions enable the processing of data in parallel and can be used to execute multiple PL/SQL programs concurrently.

The correct answer is Option C) DBMS_SQL. This option does not help in executing multiple PL/SQL programs simultaneously because it is primarily used for dynamic SQL execution and does not provide a direct mechanism for concurrent execution of PL/SQL programs.
