Question

%macro example     
%let begdate = ’01Nov2004’d;
     %let enddate = ’30Nov2004’d;
    proc sort data=test out=test2;
    where date between &begdate and &enddate;
    by date;
    run;
%mend example;

此代码给出了错误：ERROR: Syntax error while parsing WHERE clause. 但是，当我简单地用相应的值替换＆amp; begdate和＆amp; enddate时，它就可以工作。

Answer 1

我通常这样经营：

%macro example     
%let begdate = 01Nov2004;
     %let enddate = 30Nov2004;
    proc sort data=test out=test2;
    where date between "&begdate"d and "&enddate"d;
    by date;
    run;
%mend example;

我只是删除了日期格式的任何假设，并将代码中的宏变量称为字符串。希望这会有所帮助!!
