So my ideal query (not-working) would look like Webcreate function wm_concat_clob (... in your db in the sys-schema first. They should be based on code like provided by the answer from Dart XKey (maybe copied from asktom/Tom Kyte) create public synonym wm_concat for sys.wm_concat_32767 (I would generally let the wm_concat point to the likely faster wm_concat_32767 rather than wm_concat_clob) http://dba-oracle.com/t_wm_concat_sql_function.htm simple truth distilled water
