Displaying messages in procedure

Question

I have a procedure which displays the total count of students from college.
CREATE OR REPLACE FUNCTION count_stu
RETURN number
AS
temp NUMBER(4);
BEGIN
SELECT count (distinct ID) INTO temp FROM registration;
RETURN temp;
END;
If i want to display a message like:
The total no.of students are:
then the total count
is it possible?

Answer 1

I have a procedure but you gave function code
try this...
select 'The total no.of students are:' || count_stu from dual; (or)
CREATE OR REPLACE FUNCTION count_stu RETURN varchar2 AS
temp varchar2(100);
BEGIN
SELECT 'The total no.of students are:' || count (distinct ID) INTO temp FROM registration;
RETURN temp;
END;
select count_stu from dual;
