	DECLARE
  v_HIREDATE DATE := '2000-SEP-28';
  v_empid EMPLOYEES.EMPLOYEE_ID%TYPE;
  v_empfirstname EMPLOYEES.FIRST_NAME%TYPE;
  v_emplastname EMPLOYEES.LAST_NAME%TYPE;
  v_emphiredate EMPLOYEES.HIRE_DATE%TYPE;
  
  	CURSOR C_DATE_CUR(v_HIREDATE DATE) IS
    SELECT  EMPLOYEE_ID, FIRST_NAME, LAST_NAME, HIRE_DATE FROM EMPLOYEES;
  BEGIN
	  OPEN C_DATE_CUR();
    FETCH C_DATE_CUR INTO v_empid, v_empfirstname, v_emplastname, v_emphiredate;
    WHILE C_DATE_CUR%FOUND LOOP
      IF v_emphiredate>v_HIREDATE THEN
      dbms_output.put_line(v_empid||','||v_empfirstname||','||v_emplastname||','||v_emphiredate);
      END IF;
      FETCH C_DATE_CUR INTO v_empid, v_empfirstname, v_emplastname, v_emphiredate;
      END LOOP;
    CLOSE C_DATE_CUR; 
  END;
That is my code and it has error on line 11
this is the error:


Error report -
ORA-06550: line 11, column 9:
PLS-00306: wrong number or types of arguments in call to 'C_DATE_CUR'

You've declared a parameter for that cursor.
So you need to pass a parameter to it when you open ii - in the brackets after the cursor name.

... and as the parameter is not used in the cursor, you don't need it in the declaration.

Note that you can use it in a WHERE condition of the cursor and omit the IF test in the code.

You could also use a cursor loop and let Oracle manage the OPEN, FETCH and CLOSE parts.

And another thing Smile

You might be better off writing your own code rather than copying someone else's bugs. Was what you have posted copied from here?

Help you do what exactly?

Did you copy the code from that 10 year old thread?
If so - why? It states in the thread it doesn't work.
In the post after the one you copied from Barbara goes into some detail as to what is wrong with it. Did you read and understand that post?

Write an anonymous PL / SQL block that defines the C_DATE_CUR cursor. Set a parameter from the DATA data type to the cursor and display the details (number, surname and date of entry) for all employees who arrived after the date entered. Test for 28-SEP-00 and 07-FEB-01.

That is my task

It is amazing what pops up if you just copy/paste posted code into Google Smile
OP must be working on college homework questions, doing a course which is using quite old material, I think it may be based on the Oracle Uni pl/sql 11g basics course. Nothing wrong with that, I don't think the pl/sql basics haven't changed, but there are lot of new features in the last 10 years.

Hmm. I never would have thought to paste in whole code for a google search. Now that I've learned something new, I'd normally ask if I can go home now. But of course, we all are already at home ..... Smile
