wepnop Posted June 5, 2011 Share Posted June 5, 2011 I need to get the max of the field called ID, from the table ordenador. This is my actual code: $cons = "SELECT MAX(ID) FROM `ordenador`"; $maxrow = consultar_bd($cons); $id_contiene = $maxrow['ID']; consultar_bd is a function that executes a sql query and returns a fetched result as a array.

wepnop Posted June 5, 2011 Author Share Posted June 5, 2011 Sorry maybe its that my english is bad, but i think i asked it: What i need is to get the max of the ID value in the ordenador table using php + mysql. Thats the code i was using but it dont works, when i try to get the ID it says that index dont exist. I need some way to know and store in a php variable what is the higest ID value.

lordshoa Posted June 5, 2011 Share Posted June 5, 2011 I sort of under stand can you do a orderby desc and the pick the first id so you get the highest number ? Do you have a feild ID in the ordenador table or is it id $cons = "SELECT `id` FROM `ordenador` ORDERBY DESC LIMIT =1"; Link to comment https://forums.phpfreaks.com/topic/238477-geting-max-of-a-mysql-field/#findComment-1225461 Share on other sites More sharing options...
