You don't need to use a START WITH, CONNECT BY clause. The table NBI_DIM_OBS_FLAT does all that work for you.This table gives you all descendants of the PARENT_OBS_UNIT_ID value (including a record for the parent itself), so by joining to this table and having that field as a required parameter, you will always get every project associate to that node or any descendant.here's some sample code, its for 8.1, for 7.5.3 - replace INV_INVESTMENTS and INV_PROJECTS with SRM_P.. and PRJ_P.. SELECT II.CODE AS PROJECT_ID ,II.NAME AS PROJECT_NAMEFROM INV_INVESTMENTS IIINNER JOIN INV_PROJECTS IPON II.ID = IP.PRIDINNER JOIN PRJ_OBS_ASSOCIATIONS POAON II.ID = POA.RECORD_IDAND POA.TABLE_NAME = 'SRM_PROJECTS'INNER JOIN NBI_DIM_OBS_FLAT NDOFON POA.UNIT_ID = NDOF.CHILD_OBS_UNIT_ID WHERE NDOF.PARENT_OBS_UNIT_ID = 5002097; Message Edited by DeclanKenny on 09-15-2008 02:20 PM [left]
