Jorge estévez	Thursday 16 July 2009 10:26:04 am I need to do a fetch of nodes, about 5000 scatered over a big tree structure of the site just to display th node´s names. I takes very long just to "fetch" them all, and my PC memory gets exhausted. How can I fetch them not affecting the memory of my PC and speeding up the fetch Any code that iterates and can help me clean memory... Any solutions/tips please! thanks Diseño Web Cuba Web Design Cuba www.elfosdesign.com

Thursday 16 July 2009 1:35:51 pm The best would probaly be to use custom fetch function / template operator (with custom sql). eZ Online Editor 5: http://projects.ez.no/ezoe \|\| eZJSCore (Ajax): http://projects.ez.no/ezjscore \|\| eZ Publish EE http://ez.no/eZPublish/eZ-Publish-Enterprise-Subscription @: http://twitter.com/andrerom
Jorge estévez	Friday 17 July 2009 8:46:04 am Thanks, The operation I am trying to make consumes time, but this operation will not me made often, so time is not a matter at all. Memory is still my main issue (I am developing under windows and the OS tells me that I am consuming memory resources) Can I somehow fetch blocks of nodes and in between clean memory and start over again using offset (within the fetch function)? Any pseudocode I coul use please... I am trying to avoid a custom fetch. thanks, jorge Diseño Web Cuba Web Design Cuba www.elfosdesign.com
