Window functions in FedSQL?

I'm trying to do:

SELECT ROW_NUMBER() OVER(PARTITION BY ID) FROM tableA;

Will FedSQL give me window functions to do this?

No, there are other ways to accomplish this, via a data step or PROC usually.

Not sure about FedSQL, but but in PROC SQL you could mimic some of the window function by letting SQL re-merge statics with original data. That will be forced when there is mismatch between the GROUP BY clause and columns in the SELECT clause that doesn't contain any aggregate function. Also, this method is probably not as efficient a "true" window function performs with an appropriate implementation.

 

Can't tell though how you example should be resolved, a simple have and want sample data would help.

FedSQL does not currently support windowing functions.
