FAQ

Q: Why use saspy instead of using ssh tunnels?

A: Although we can use ssh tunnels to transfer data and execute SAS commands, there are many restrictions: it only supports ssh connection. Using saspy, the official Python interface to SAS, we can enable all connection types, without reinventing the wheel, e.g. we can also connect to a local SAS installation with the same syntax, or connect to a remote SAS Viya through http. In addition, SAS sessions in saspy will not end until you terminate it (or encounter net work issues), it will be nice to execute multiple SAS code one by one, not necessarily putting them in one script and execute the whole script at once. Also, with the update of saspy over time, sasr will be easily extensible, to include functionalities other than transferring data and executing SAS code.
