用引號將SAS宏變量賦值給數據步驟var

Question

如何使以下語句有效？

%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; 

它錯誤返回 ERROR 386-185：期待的算術表達式。

錯誤200-322：該符號不被識別，將被忽略。

錯誤76-322：語法錯誤，語句將被忽略。

Answer 1

可以使用SYMGET（）函數來檢索值的宏變量，而不必擔心任何宏觀引用（至少在進行檢索的步驟中）。

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

如果你真的需要引用宏變量的值，並用它來生成一個帶引號的字符串然後使用引號（）函數，以確保所有嵌入式引號正確一倍，這樣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數來解決這個問題，

/* 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;
