I've been analyzing your table Arda. To create the query just to fill the column POSITION in function of RANKING can be easily done; however I'd like to know why would you want to use the UPDATE query (shown in you document file) to change POSITION manually, this would alter the right order that you desire and POSITION wouldn't be in function of RANKING anymore. By the way, I'm Peruvian so I can speak Spanish too. Thanks

Okay, here you go: UPDATE `mtotal`.`ARDA` target JOIN ( SELECT `ID_ART`, (@rownumber := @rownumber + 1) AS rownum FROM `mtotal`.`ARDA` CROSS JOIN (SELECT @rownumber := 0) r ORDER BY `RANKING` DESC ) source ON target.`ID_ART` = source.`ID_ART` SET `POSITION` = rownum; The idea is to update the target table by joining the table with generated row numbers.
