Question

我想写一个运行追加10个查询结果的宏，我用SAS宏代码生成。

%MACRO APPENDTEST;
    PROC SQL;
        %DO I = 1 %TO 12
            CREATE TABLE WORK.APPENDTEST AS
            SELECT t1.OrderID, t2.Name, t3.Product, t1.Date, t1.Units
            FROM DVJAYESH.CANDY_SALES_HISTORY t1, 
                 DVJAYESH.CANDY_PRODUCTS t3, 
                 DVJAYESH.CANDY_CUSTOMERS t2
            WHERE (t1.ProdID = t3.ProdID AND t1.Customer = t2.CustID)
            AND t1.Date BETWEEN CATS('01', %PUT(CATS(&I), $MTH_NAME.), '2003')D AND 
                            CATS('31', %PUT(CATS(&I), $MTH_NAME.), '2003')D
            ORDER BY t1.Date, t2.Name, t3.Product;
        %END;
    QUIT;
%MEND APPENDTEST;

%APPENDTEST;

我收到多个错误。第一个是 - A character operand was found in the %EVAL function or %IF condition where a numeric operand is required.

请解释并纠正。

仅供参考：我是SAS编程的新手。我使用SAS ENTERPRISE GUIDE

你的宏将创建work.appendtest 12次。每次都写过以前的副本。您可以尝试在do循环之前放置create语句。我更喜欢略有不同的方法。

%Macro apendtest;

  delete data = appendtest; /* you will get a warning if it doesn't exist;*/
  %do i = 1 %to 12;
     proc sql;
          create table temp as
             select ......
             from...........
             where ..........
     quit;
     proc append base = appendtest data = temp; run;
  %end;

%Mend appendtest;

如果你想看每个临时表使用temp＆amp; i

使用％put和cats编写带有SAS MACRO代码的SQL语句
