To answer this question, you need to understand triggers and their capabilities.
Triggers are database objects that are automatically executed in response to specific events, such as changes to data in a table. They can be used to enforce business rules, perform auditing, or automatically update related data.
When a trigger is fired, it can execute SQL statements or call other database objects. In this case, the CALL statement is used to call a stored procedure. Therefore, the correct answer is C) Stored procedure.
Let's go through each option to understand why it is correct or incorrect:
Option A) Package - A CALL statement inside a trigger body cannot directly call a package. However, a stored procedure or function within the package can be called using the CALL statement.
Option B) Stored function - A CALL statement inside a trigger body can call a stored function. This is a valid option, but it is not the correct answer given in the question.
Option C) Stored procedure - A CALL statement inside a trigger body can call a stored procedure. This is the correct answer, as stated in the question.
Option D) Another DB trigger - A CALL statement inside a trigger body can call another trigger. However, it is generally not recommended to have triggers calling other triggers directly, as it can lead to complex and difficult-to-maintain code.
Therefore, the correct answer is C) Stored procedure. This option is correct because a CALL statement inside a trigger body enables the calling of a stored procedure.
