I don't think you need to use any loops in sql...I believe the following would do the same thing as your code above.... <cfquery name="getAllServices" datasource="#REQUEST.theDatabase#"> UPDATE TPSservices SET priority = priority - 1 WHERE active = '1' AND priority > <cfqueryparam value="#getDeletedPrior.priority#" cfsqltype="cf_sql_integer" /> </cfquery> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Introducing the Fusion Authority Quarterly Update. 80 pages of hard-hitting, up-to-date ColdFusion information by your peers, delivered to your door four times a year. http://www.fusionauthority.com/quarterly Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:258364 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
