用引号将SAS宏变量赋值给数据步骤var

Question

如何使以下语句有效？

%let qccomment= /n ORACLE execute error: ORA-20001: User xyxlll 
     does not have acccess to the gva BA_DEV ORA-06512: at 
     "M_UTIL", line 51 ORA-06512: at line 1. /nTable XY_XY does not exist 
     (Oracle extract data failed); 

%put &qccomment; 
data null; 
    i ="&qccomment"; 
    put i; 
run; 

它错误返回 ERROR 386-185：期待的算术表达式。

错误200-322：该符号不被识别，将被忽略。

错误76-322：语法错误，语句将被忽略。

Answer 1

可以使用SYMGET（）函数来检索值的宏变量，而不必担心任何宏观引用（至少在进行检索的步骤中）。

data _null_; 
    i = symget('qcomment'); 
    put i= ; 
run; 

如果你真的需要引用宏变量的值，并用它来生成一个带引号的字符串然后使用引号（）函数，以确保所有嵌入式引号正确一倍，这样生成的字符串是有效的字符串字面量。

data _null_; 
    put %sysfunc(quote(&qcomment)); 
run; 

Answer 2

您需要使用宏引用函数来解决这个问题，

/* Using %BQUOTE in let statement to quote the string */ 
%let qccomment= %bquote(/n ORACLE execute error: ORA-20001: User xyxlll 
    does not have acccess to the gva BA_DEV ORA-06512: at 
    "M_UTIL", line 51 ORA-06512: at line 1. /nTable XY_XY does not exist 
    (Oracle extract data failed)); 

%put &qccomment; 
data null; 
    i ="&qccomment"; 
    put i; 
run;
