No doubt about it.
However, flyerr的问题是" data step v.s. Proc sql in creating new
variables".
Such as:

Which VAR statement successfully completes

A.

发帖数: 188 | 5 There are few different methods to put multigraphs on one page. The idea is
to generate the graphs first and then use PROC GREPLAY. Below is a simple
sample code to do this. I ever used another more flexible way to generate
graphs, but could not find the code, and also forgot how to do so ...

do i=1 to 100;
x = rannor(10);

z = rannor(3)+2;

发帖数: 493 | 10 我猜1。Proc SQL的第一步是判断有没有equijoin，如果不是才会用step loop形成
Cartesian product。所以normalize database才这么重要。
可以看下面这个例子里面log的执行方案，2比1复杂的多。
data a b;
set sashelp.class;
rename name = id;
run;
proc sql _method;
select a.* from a, b
where a. id =b.id;
quit;
proc sql _method;
select a.* from a, b
where a.id in
(select distinct id from b);
quit; |

发帖数: 772 | 11 试试这个办法
1. 通过sashelp.vcolumn 这个view， 找出你的data里面所有 format 不为空的数值变量的
变量名和format，然后分别把他们存为 macro variable
2.读你的data， 对每个macro里面的variable，用 put转换为对应的format后看是不是
'NA' |
