To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) If errors occur during the compilation of a trigger, the trigger is still created.
This option is correct. In Oracle, even if errors occur during the compilation of a trigger, the trigger is still created. However, it may not function correctly if there are compilation errors.
Option B) If errors occur during the compilation of a trigger, you can go into SQL *Plus and query the USER_TRIGGERS data dictionary view to see the compilation errors.
This option is incorrect. The USER_TRIGGERS data dictionary view does not provide information about compilation errors. It provides information about triggers, such as their names, types, and status, but not the compilation errors.
Option C) If errors occur during the compilation of a trigger, you can use the SHOW ERRORS command within iSQL *Plus to see the compilation errors.
This option is correct. In Oracle, you can use the SHOW ERRORS command within iSQL *Plus to see the compilation errors for triggers. This command displays the error messages and line numbers associated with the compilation errors.
Option D) If errors occur during the compilation of a trigger, you can go into SQL *Plus and query the USER_ERRORS data dictionary view to see compilation errors.
This option is correct. In Oracle, you can query the USER_ERRORS data dictionary view in SQL *Plus to see the compilation errors for triggers. This view contains information about the errors, including the line numbers and error messages.
The false statement is Option B. The USER_TRIGGERS data dictionary view does not provide information about compilation errors.
