Hello, >>will all users be able to access the all objects. [CJ] I think so, although you can use any of your application {CJ] tables with 100-500 rows instead of ALL_OBJECTS. >>my user wants to query for certain range of month who are on-vacation? >>example: user enter starting date 10/2004 ending date: 02/2005 [CJ] Add this date range condition as predicate to the original query. SELECT id, TO_CHAR(mnth, 'MM/YYYY') FROM tmp a, (select trunc(add_months(sysdate, - rownum + 1), 'MM') mnth from all_objects union all select trunc(add_months(sysdate, rownum), 'MM') mnth from all_objects) b WHERE b.mnth > a.startdate and a.mnth <= enddate AND a.startdate <= :stdt AND a.enddate => :enddt Regards, Charu. ********************************************************* Disclaimer: This message (including any attachments) contains confidential information intended for a specific individual and purpose, and is protected by law.
