Answer / aritra

TRY THIS ONE ...

CREATE TABLE FARE_DETAILS
( SOURCE VARCHAR2(100),
DESTINATION VARCHAR2(100),
FARES NUMBER(10,2));

create or replace procedure PROC_TCKT_RESERVATION
(m_source IN VARCHAR2,
m_destination IN VARCHAR2,
m_age IN NUMBER
)
is
v_source FARE_DETAILS.SOURCE%TYPE;
v_destination FARE_DETAILS.DESTINATION%TYPE;
v_fares FARE_DETAILS.FARES%TYPE;
v_fares_out FARE_DETAILS.FARES%TYPE;
begin
IF m_source= m_destination THEN
RAISE_APPLICATION_ERROR(-20001,'SOURCE, DESTINATION
SHOULD NOT BE SAME');
END IF;
SELECT FARES
INTO v_fares
FROM FARE_DETAILS
WHERE SOURCE= m_source
AND DESTINATION= m_destination ;
IF m_age>=60 THEN
v_fares_out:= (v_fares-v_fares*0.3);
DBMS_OUTPUT.PUT_LINE('GIVEN AGE IS FOR SENIOR CITIZEN,
FARE IS '||v_fares_out);
ELSE
v_fares_out:= v_fares;
DBMS_OUTPUT.PUT_LINE(' FARE IS '||v_fares_out);
END IF;

EXCEPTION
WHEN NO_DATA_FOUND THEN
RAISE_APPLICATION_ERROR(-20001,'NO DATA FOUND ..ENTER
COREECT SOURCE/DESTINATION');

CREATE TABLE FARE_DETAILS

BEGIN

IF UPPER(TRIM(I_SOURCE)) = UPPER(TRIM(I_DESTINATION)) THEN

END IF;

SELECT FARES INTO L_FARES FROM FARE_DETAILS

Hi Aritra, Kavitha,
Ur logic is correct, but it's not complete all point, where ur program is identify tickets are available or not then u program should calculate fare and all details.
