Hello, I know this question has been sent a long time ago lol but I can give an answer that will be useful for all generations !!! In the QueryDesigner of iReports, choose "PLSQL" as Query Language. Then write your call to procedure/function like this : SELECT My_Function_Name($P{My_Parametre_1}, ..., $P{My_Parametre_N}) or CALL My_Procedure_Name($P{My_Parametre_1}, ..., $P{My_Parametre_N}) I've already tried it and it's OK. Hopefully it will help someone... Post Edited by jcvlad at 01/25/2011 15:47
