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;

返回错误错误 386-185：需要算术表达式。

错误 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。

你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;

谢谢你，维尚。它可以工作，但在我的实际情况下，宏变量是自动生成的，但不是直接分配的。以前的汤姆的解决方案可以帮助我。 :)
@Greatvia- 如果您可以在问题中提及与您的要求相同的内容，那就太好了，就像在您的问题中您要求解决错误一样。今后请牢记这一点。

【解决方案2】：

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

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

如果您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，那么请使用 QUOTE() 函数确保任何嵌入的引号都正确加倍，以便生成的字符串是有效的字符串文字。

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