I have looked at proc surveyselect - I am not sure how to specify that the random sample be based on the identifier.    I am trying to take a dataset of 200,000 records all with a unique identifier, and randomly sample 30,000 records based on the identifier. I want to sample the data on identifier, because that is the only variable that contains a random segment, so if I sample on that variable, I can ensure the sample is random.    Please let me know what other specific info you need - I am really at a loss on how to execute this task.  ...

I am looking to take a random sample using an identifier. I already isolated the part of the identifier that is random and created a separate variable, but how do I create a sample of the main data by randomly selecting on the identifier?    Ideally this would be replicable, so I want to be able to say - "SAS, randomly select 100,000 records where the identifier = 123"    Any help would be greatly appreciated.  ...
