I see the error but object cis605 is valid. Any ideas what I am missing?

Using the ORD table create a stored function called custord that will use a customer id (CUSTID) that will return the sum of the specified customer id TOTAL field.
When your function has been stored run the following SQL:
begin
dbms_output.put_line(‘customer 102 total is ‘ || custord(102));
end;

Your output should look like:

Answer 1

Try

SHOW ERRORS FUNCTION custord

Your custord function was created with compilation errors, so there is something wrong with it. This is why you’re getting the object CIS605.CUSTORD is invalid error.
