To solve this question, the user needs to know how to check for the errors in an SQL function.
The correct answer is:
C. SHOW ERRORS
Explanation:
When a function is created with compilation errors, the SHOW ERRORS command can be issued to see the actual error message. This command displays the compilation errors of the last CREATE or REPLACE FUNCTION or PACKAGE statement that was executed in the current session. Using this command can help identify and fix any syntax errors or other issues with the function code.
Option A is incorrect because there is no SHOW FUNCTION_ERROR command in SQL *Plus.
Option B is incorrect because SHOW USER_ERRORS is not a valid command in SQL *Plus.
Option D is incorrect because SHOW ALL_ERRORS is not a valid command in SQL *Plus.
