Subject: proc sql or data step
I have to sum up variables in a dataset that has some 30 million observations.
Right now we are using proc sql to do it. But, it is taking a lot of time. How
Can I improve the performance? Can I use data step with retain? Are there any
Any help is greatly appreciated.
