A CALL statement inside the trigger body enables you to call ______.
-
A package.
-
A stored function.
-
A stored procedure.
-
Another database trigger.
Within a trigger body, the CALL statement is used to invoke a stored procedure. Triggers can call stored procedures to execute complex business logic or perform operations that cannot be done directly in trigger SQL. You cannot CALL packages, functions (use direct invocation), or other triggers from within a trigger.
To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) A package - This option is incorrect because a CALL statement inside a trigger body is not used to call a package. Packages are typically used to group related functions, procedures, and variables together.
Option B) A stored function - This option is incorrect because a CALL statement inside a trigger body is not used to call a stored function. Stored functions are typically used to perform a specific task and return a value.
Option C) A stored procedure - This option is correct. A CALL statement inside a trigger body enables you to call a stored procedure. Stored procedures are blocks of code that can be executed with specific input parameters and can perform various tasks in a database.
Option D) Another database trigger - This option is incorrect because a CALL statement inside a trigger body is not used to call another database trigger. Triggers are automatically executed in response to specific events and are not typically called directly by other triggers.
The correct answer is C) A stored procedure. This option is correct because a CALL statement inside a trigger body can be used to call a stored procedure and execute the code within it.
