The exception for "e_no_deptno" is not raised.
If I enter a valid deptno for example 10 - 50 then it prints
"deptno exist in deptt table"
However when I enter a deptno that does not occur in the table no excpeiton is raised, but PL/SQL code is executed successfully. The line
"error number does not exist"
Never gets printed.
Why?
ACCEPT p_number PROMPT 'Please enter department number: '
DECLARE
e_no_deptno EXCEPTION;
v_deptno deptt.deptno%TYPE := TO_NUMBER(&p_number);
CURSOR c_deptno is SELECT DEPTNO FROM DEPTT;
BEGIN
For i IN c_deptno loop
IF i.deptno = v_deptno THEN
DBMS_OUTPUT.PUT_LINE('deptno exist in deptt table');
ELSIF c_deptno%NOTFOUND THEN
RAISE e_no_deptno;
END IF;
END LOOP;
EXCEPTION
WHEN e_no_deptno THEN
DBMS_OUTPUT.PUT_LINE('error number does not exist in deptt table');
END;

Remove %notfound and just check for if-else condition.
ACCEPT p_number PROMPT 'Please enter department number: '
DECLARE
e_no_deptno EXCEPTION;
v_deptno deptt.deptno%TYPE := TO_NUMBER(&p_number);
CURSOR c_deptno is SELECT DEPTNO FROM DEPTT;
BEGIN
For i IN c_deptno loop
IF i.deptno = v_deptno THEN
DBMS_OUTPUT.PUT_LINE('deptno exist in deptt table');
ELSE
RAISE e_no_deptno;
END IF;
END LOOP;
EXCEPTION
WHEN e_no_deptno THEN
DBMS_OUTPUT.PUT_LINE('error number does not exist in deptt table');
END;
