Our journey with SAS's StoredProcessService object continues...

Check out this code:


string newParms = "outdata=WORK.TEST";
Common.SasLanguageService.Async = true;
StoredProcessService sp = Common.SasLanguageService.StoredProcessService;
sp.Repository = storedProcLibrary;
sp.Execute(storedProcedureName, newParms);


Standard stuff when working with the stored process server through VB or C# (or any other means of hitting these dlls).

Funny thing is the SAS log shows that the macro assignment of newParms never takes place. Hence, &outdata is undefined:

SYMBOLGEN: Macro variable OUTDATA resolves to

Commenting out the Async makes this all work:

SYMBOLGEN: Macro variable OUTDATA resolves to WORK.ALAN_20110418_070053

Now, even wiring up the event handlers for SubmitComplete do not fix the issue. Seems like a bug but I'll let the guys in R&D figure it out. If you have to waste a lot of time on it, however, keep in mind the nuances here until SAS R&D dives in.

Well, back out to the far left field where I hang out. Time to work on the business problem.

It seems like you're trying it the hard way using SAS IOM via COM. Did you know that there might be a managed wrapper in your Integration Technologies folder if you have SAS9.2?

Look for a StoredProcessService.dll and the documentation file StoredProcessService.chm in the %programfiles%\SAS\Shared Files\Integration Technologies folder.

BTW: i really like your blog!

Now THAT's what I have been looking for for a long, long time. Playing with the help file now...

More info to come later.

Well, the issue with the .NET component is that it relies on a Stored Process Server already being set up (from what I could tell). Hence, you can't just pass the file locations and the parms and execute. I would love it if this wasn't the case but that is what I gleaned from my short exploration.

I will work on it more once I clear a deadline that I have to meet.

I did not have much time to investigate the .NET component either. I discovered it by accident :P (like all nice SAS stuff it is hidden very good) and only used it in a simple demo, but as far as i understand it, the stored process has to be already registered in the metadata server.
If you just want to execute some SAS code from a file location (which is not registered in the metadata) you should use a workspace server, right?

Well good luck on meeting your deadline. It would be very nice if you could share your experience with the managed assembly. I guess there are only very few people like us who use SAS/ Integration Technologies in combination with Microsoft technology.

It works ok for me if I set Common.SasLanguageService.Async = false under C#.

Async = false is the default which is why including it works or commenting out the line works.
