Bump... Casey - is this method thread safe? -----Original Message----- From: Brook Davies [mailto:cft...@logiforms.com] Sent: December-13-11 10:15 PM To: cf-talk Subject: RE: <cftransaction isolation="repeatable_read">

If so you only need one query which will still output rows like the first query with OUTPUT. <cfquery name="getEvents"> update t1 set t1.enabled = 0 OUTPUT inserted.ID, inserted.cfc, inserted.runMethod, inserted.arguments, inserted.frequency, inserted.frequencytype from scheduledTasks t1 inner join scheduledTasks t2 on t1.ID = t2.ID where t2.enabled = 1 and t2.nextDate < <cfqueryparam cfsqltype="cf_sql_timestamp" value="#createodbcdatetime(Now())#"> and t2.startDate < <cfqueryparam cfsqltype="cf_sql_timestamp" value="#createodbcdatetime(Now())#"> and t2.endDate > <cfqueryparam cfsqltype="cf_sql_timestamp" value="#createodbcdatetime(Now())#"> </cfquery> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:349127 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
