Dashboard cursor cache query statement

Question

hi,
i would like to ask if there is a way to get the query statement that was executed in getting the dashboard result. i'm thinking if it is possible to get this programmatically, like using a session variable.
basically, i would like to replicate the data in the dashboard, and i would like to use the query statement (by another application) to be executed via obiee web service.
thanks.

I think you are addressing a common problem in datawarehouses... there are staging tables, some times empty, some times with millions of rows... so, maybe the statistics are not reallistic... What is the result of the following query:
select num_rows, last_analyzed from dba_tables where table_name = '<your_table>';
If this is the problem, you should to consider one of the following strategies:
1) Analize the table when is "full" and assure that never runs an analize table (or a gather_schema_stats) over this table. This strategy works fine if all days the table is populated with similar data... but maybe you need to change a gather_schema_stats job schedule... you should be aware of when and how the statistics are updated
2) Populate the table, then run a gather_table_stats over the table, wait for the completion of the gathertable_stats_, and finally trigger the 6am process... maybe you need to schedule the process before 6am because the statistics gather process
I hope this helps
