No idea. But, what will you do with query once you extract it from RDF file?

When you said 'read query from rdf file at runtime' did you mean 'read the parameters that were used when running the report'?

When you said 'need to buffer the data of specified reports' do you, again, mean 'buffer the parameters that were used when running the report'?

For me:
Query=SQL, data=result lines

Agreed?

Why wouldn't you (instead of such an unusual operation of extracting a query from a report and doing something with it in a form) simply schedule a job which would create a report?

@ djmartin

Agreed

@littlefoot

what can i say, it is the requirement from my boss......

basically the problem is that, sometime the connection is lost at the plant ( ERP for a cement company) and the work is interupted . So i order to avoid the interuption in work i need to buffer some data in excel file , so that data can be used and work not interrupted even if connection is lost.

Regards

You said "need to buffer the data of specified reports after lets say every 20 minutes into an excel file". Do you mean KEEP the last 20 minutes worth of data in an excel file?

Another idea: how about creating a materialized view in the plant database which would refresh periodically and enable you to view data, nevertheless the connection to the remote database is established or not?

How are you running this report?

Have you considered have a 'dbms_job' which runs a PL/SQL deck every 5 minutes and creates a new copy of a '.csv' file?

Does it mean that there are several reports involved (so you'd extract a different query every time) or that report's query is being changed frequently (so you have to extract its new copy every time)? Because, a simple one-time "copy-paste" technique would work, right? But that's obviously too simple.

Okay, change all the reports so that they first write the output to the Excel file and then use that file to create the paper copy. Alternatively, as the paper reports are working, add a 'pre-report' report that produces the Excel file. That way, if the link fails during the second part of the process (writing the existing paper report) then the local Excel copy is available already.

No idea. Never used it. I was thinking of writing a script that produces a 'csv' file and running it before the current report is called.

Search this forum for 'rpt2xls'. There are a few interesting threads.

Then write the output as a flat file using 'text_io'. Why does Excel have to be used?

There would be a flat file per reprot and if you wish to you could keep hyperlinks to them in an Excel file.
