具有逗号的SAS宏变量要转换为带逗号的单引号

Question

有人可以帮助我如何使用单引号更新宏变量。

我从数据集中获取数字作为逗号分隔值，如下所示：

2108008080、2108008081、2108888082、2108858090、213856345 等我必须在 SQL 中传递每条记录，其中条件为 Phone_numbers in (¤t_macro_variable)。为此，我必须在每个值周围添加单引号，因为 Phone_numbers 列是 Oracle DB 的字符字段。

非常感谢任何帮助。我无法从 SAS 社区获得太多帮助。

Answer 1

quote 函数应该可以解决问题。您必须遍历 stringLine 中的所有单词并添加引号。

%let macroVar = %str(2108008080, 2108008081, 2108888082, 2108858090, 213856345);

data _null_;
    n = count("&macroVar",",");
    length 
        quotedword 00.;
    quotedword = "";
    do i = 1 to n+1;
        word = scan("&macroVar",i,",");
        y = quote(compress(word));
        quotedword = strip(quotedword) || "," || strip(y);
    end;
    quotedword = substr(quotedword,2); /* removing first comma from beginning */
    call symputx("macroVarUpdated",quotedword);
run;

%put &macroVar;
%put &macroVarUpdated;

Answer 2

使用 PROC SQL 和 select ... into 语法：

/* Build list of quoted phone numbers separated by a comma */
proc sql ;
  select cats("'",phone_number,"'") into :PHONELIST separated by ',' 
  from phonedata ;
quit ;

/* Then pass it into your Oracle query... */
proc sql ;
  select vars
  from ora.table
  where phone in(&PHONELIST) ;
quit ;

Answer 3

你试过CATQ()功能了吗？使用 1 修饰符生成单引号。使用 a 修饰符来引用所有术语。使用 c 修饰符生成逗号作为输出分隔符。

%let x=2108008080, 2108008081, 2108888082, 2108858090, 213856345;
%put %sysfunc(catq(1ac,&x));

产生：

'2108008080','2108008081','2108888082','2108858090','213856345'
