没理解，举个例子

data class;
        set sashelp.class;
run;
proc sql;
        create table class1 as
                select sex,height,
                                sum(height) as h_sum,
                                height/ calculated h_sum as percent format=percent12.2
                        from class
                        group by sex
        ;
quit;
