Which statement is valid when removing procedures?

  1. Use a drop procedure statement to drop a standalone procedure.

  2. Use a drop procedure statement to drop a procedure that is part of a package. Then recompile the package specification.

  3. Use a drop procedure statement to drop a procedure that is part of a package. Then recompile the package body.

  4. For faster removal and re-creation, do not use a drop procedure statement. Instead, recompile the procedure using the alter procedure statement with the REUSE SETTINGS clause.


Correct Option: A

AI Explanation

To answer this question, you need to understand the process of removing procedures in a database. Let's go through each option to understand why it is correct or incorrect:

Option A) Use a drop procedure statement to drop a standalone procedure. This option is correct. When you want to remove a standalone procedure, you can use the "DROP PROCEDURE" statement to delete it from the database.

Option B) Use a drop procedure statement to drop a procedure that is part of a package. Then recompile the package specification. This option is incorrect. If a procedure is part of a package, you need to drop the entire package using the "DROP PACKAGE" statement, not just the procedure. Recompiling the package specification alone will not remove the procedure from the database.

Option C) Use a drop procedure statement to drop a procedure that is part of a package. Then recompile the package body. This option is incorrect. Similar to option B, if a procedure is part of a package, you need to drop the entire package using the "DROP PACKAGE" statement, not just the procedure. Recompiling the package body alone will not remove the procedure from the database.

Option D) For faster removal and re-creation, do not use a drop procedure statement. Instead, recompile the procedure using the alter procedure statement with the REUSE SETTINGS clause. This option is incorrect. While recompiling a procedure using the "ALTER PROCEDURE" statement with the "REUSE SETTINGS" clause can be faster, it does not remove the existing procedure from the database. It only updates the definition of the procedure without dropping and recreating it.

The correct answer is A) Use a drop procedure statement to drop a standalone procedure. This option is correct because when removing a standalone procedure, you can use the "DROP PROCEDURE" statement to delete it from the database.
