I mean for example this my customer and who was referred by each and every customer . I want to display up to five level up and down referral using one query .but without using joint . For example : Let us consider cust_id 17 is prakash . prakash was refered by mahul (cust_id :13) mahul was refered by mohan(cust_id:9) mohan was refered by ram(cust_id:6) Three level up (it may be increase in future ) prakash refered one person raman (cust_id:24) raman refered one person somu (cust_id:25) some refered one person usha(cust_id :29) -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
