宏变量不能用单引号解析.您还缺少 FROM 子句，并且宏参数是作为位置提供的(而不是名称=值对).请尝试以下操作:

Macro variables will not resolve in single quotes. You are also missing the FROM clause, and the macro parameter was being provided as positional (instead of name=value pair). Try the following:

%macro refreshments(beverage_type=);
  proc sql;
  select * 
    from YOURTABLE
    where drink_type = "&beverage_type";
%mend;

%refreshments(beverage_type=Sprite);
