Extracting SQL statement from a Webi document's data provider using SDK.

Question

Hi all,
Is it possible to extract the SQL statement from an existing Webi document's data provider using BO SDK?  I've searched through the class library but haven't found any information on this yet.  If you have done it, could you provide some guidance.  Many thanks.

I found the following Java code that might be of some help to you. I realize you are using .NET but this might push you down the right path.
The trick here is to use the Report Engine SDK to get the DataProvider of the DocumentInstance. Then, look at the SQLDataProvider to get your SQLContainer.
My apologies for the poor formatting. This didn't copy and paste over to the forums very well. I've cleaned up as much as I could.
