Try someting like

Oracle:

Load A,B,C

where Date=Date(Today())

if noOfRows('Oracle') =0 Then

Load A,B,C

from Excel

ELSE

//do nothing

END IF

Hi Tim,

Thanks for ur reply.

For the first time reloading it will work. if the data is already there in qvd but not refreshed, in that case noofrows() will not be '0'. How to do in this case?

Thanks

Then you want to load * from QVD right?

Oracle:

Load A,B,C

where Date=Date(Today())

if noOfRows('Oracle') =0 Then

Load A,B,C

from Excel

ELSE

//data not refreshed

Load * from QVD

END IF

you can check QVD file created time

Let vQVDPath = 'lib://Desktop/DSNVMG.qvd';

Let v_last_load_time =date(QvdCreateTime('$(vQVDPath)'),'YYYY/MM/DD') ;

if v_last_load_time < date(today(),'YYYY/MM/DD') then
  //load Excel
Else
  //Load QVD 
end if;

Assumption QVD file refresh one time a day and Main app reload same day with QVD file

Hi Tim,

Excel is having updated data.Qvd was not updated due to server down of Oracle.

What I want is If the Qvd is not updated then need to load from excel.

Thanks
