[arnab maity]

i was working with sored procedures in mysql and i had a problem while trying to initialise the in parameters of the procedures by using something as "default "as we do it in oracle. THIS IS BELOW CODE IS NOT WORKING.

CREATE PROCEDURE SP_GETADJACENT_AIRPORT(IN IP_AIRPORT_CODE VARCHAR(3),
IN IP_DISTANCE INT(10) DEFAULT 50)
BEGIN
SELECT ADA_ADJACENT_AIRPORT_CODE
FROM T_ADJACENT_AIRPORT
WHERE ADA_AIRPORT_CODE=IP_AIRPORT_CODE
AND DISTANCE<=IP_DISTANCE
ORDER BY DISTANCE;
END;
