sql查询结果如何作为变量存储在数据集中？

shiyiming

我用循环查询了work.lag数据集中z1,z2,...z10,共十个变量，并分别求和作为sum1,sum2,...sum10;
但是不知道如何存储这10个求和结果，即把它们放到一个数据集中。多谢高手指点！
%macro cov;

proc sql;
%do i=0 %to 10;
select sum(z&i) as sum&i from work.lag;
%end;
quit;

%mend;
%cov;

这样：
select sum(z&i) as sum&i into :sum&i from work.lag;

shiyiming

data tblNew;
set lag end = last;
retain sum1-sum10 0;
array z{*} z1-z10;
array sumAry{*} sum1-sum10;
do i=1 to 10;
    sumAry{i} = sum(sumAry{i},z{i});
end;
if last then output;
keep sum1-sum10;
run;

仔细看看proc sql的reference..
[code:355mao3g]proc sql ;
%do i=0 %to 10;
insert into yourdata  
select sum(z&i) as sum&i from work.lag;
%end;
;
quit;
