The ADD_PLAYER, UPD_PLAYER_STAT and UPD_PITCHER_STAT procedures are grouped together in a package. A variable must be shared among only these procedures. Where should you declare this variable?

  1. a) In the package body.

  2. b) In the data base triggers.

  3. c) In the package specification.

  4. d) In the procedures declare section using the exact name in each.


Correct Option: A

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) In the package body - This option is correct because declaring the variable in the package body ensures that it is shared among only the procedures contained within the package. The package body is where the implementation details of the package are defined, and any variables declared in the package body are accessible to all the procedures within the package.

Option B) In the database triggers - This option is incorrect because database triggers are not within the scope of the package. Triggers are separate database objects that are used to automatically execute code in response to specific events, such as insert, update, or delete operations on a table. Variables declared in triggers are not accessible within the package procedures.

Option C) In the package specification - This option is incorrect because the package specification defines the interface of the package, including the public procedures, functions, and types that can be accessed from outside the package. Variables declared in the package specification are accessible to other programs or packages that use the package, but not specifically to the procedures within the package.

Option D) In the procedures declare section using the exact name in each - This option is incorrect because declaring the same variable with the exact name in each procedure would create separate and independent variables within each procedure. These variables would not be shared among the procedures and would not serve the purpose of having a variable shared among only these procedures.

The correct answer is A) In the package body. This option is correct because declaring the variable in the package body ensures that it is shared among only the procedures contained within the package.
