Question

如何使以下声明有效？

%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;

它返回错误错误386-185：期待算术表达式。

ERROR 200-322：符号无法识别，将被忽略。

ERROR 76-322：语法错误，语句将被忽略。

Answer 1

您可以使用SYMGET（）函数检索宏变量的值，而不必担心任何宏引用（至少在执行检索的步骤中）。

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

如果确实需要引用宏变量的值并使用它来生成带引号的字符串，那么使用QUOTE（）函数确保任何嵌入的引号都正确加倍，以便生成的字符串有效string literal。

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

Answer 2

您需要使用宏引用功能来解决这个问题，

/* 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;
