Rearranging variables in a sas dataset- alphabetical order

问题

I have like 500 columns of dataset, and I want to rearrange all the variables in an alphabetical order. How can I do that in any other way than using retain statement before set statement?

回答1:

You can generate the list of variable names dynamically, and create a new dataset using PROC SQL.

proc sql ;
  select name into :VARLIST separated by ', '
  from dictionary.columns
  where libname = 'SASHELP'
    and memname = 'CLASS' 
  order by name ;
quit ;

proc sql ;
  create table ordered as
  select &VARLIST
  from sashelp.class ;
quit ;
