Hi List, We are trying to use below SQL to obtain the last time at which a package/procedure/function being modified. It seems to be working for procedure and functions, but not for the package. select to_char(LAST_DDL_TIME, 'YYYY MM DD HH:MI:SS') from dba_OBJECTs where OBJECT_NAME = 'MYPACKAGE'; Is there any other way to find out a package's source code was changed? Maybe I should look into the link between package and procedures? Thanks, Roger Xu
