Hi:
Depending on whether you want a report or an output dataset, SAS procedures that could give you that type of information is PROC MEANS, PROC TABULATE or PROC REPORT.

It looks like a report with a summary line to me. I would be tempted to use PROC REPORT with an RBREAK statement. See related post and program example here:

MS SQL does not have a built in median function. Even if SAS was going to pass through the function somehow the data would have to come back to your computer /SAS server to be processed by SAS.

Other SQL servers may, I'm not familiar with them.

If you're using SAS you're much better off using a proc tabulate or proc report or Proc Means.

proc sort data=sashelp.prdsale; by region; run;

Proc means data=sashelp.prdsale noprint;
by region;
var actual;
output out=last median(actual)=median_price sum(actual)=sum_sales;
run;
