标题: 例子：宏变量的拼接和引用
例子：
程序是这样的：
%let zd001=coilno as m_no,
         FAANFA204,
         FAANFA407_1;

%let zd002=coilno as m_no,
         FASLF006;

%let zd003=coilno as m_no,
         MCC1F025;
  中间略……
%let zd009=coilno as m_no,
         MFT1F031_1,
         MFT1F031_2,
         MFT1F031_3,
         MFT1F031_4,
         J;

%macro cre00(i);
%do j=1 %to &i;
proc sql;
create table tch100&j
as select &zd00&j from suipc000&j where coilno in (select coilno from tmp0);
quit;
%end;
%mend;
%cre00(9);

这个程序是错误的，&zd00&j的意思取zd00的值与j的值拼在一起。
SAS出现如下出错信息：
NOTE: Line generated by the invoked macro "CRE00".
1 &zd00&j from ipc_1580.suipc000&j where
-
22
1 ! coilno in (select coilno from tmp0); quit;
ERROR 22-322: Syntax error, expecting one of the following: a name, a quoted string,
a numeric constant, a datetime constant, a missing value, INPUT, PUT, USER.

现在改成这样了，还是错的

%macro cre00(zd,i);
%do j=1 %to &i;
proc sql;
create table tch100&j
as select &zd&j from ipc_1580.suipc000&j where coilno in (select coilno from tmp0);
quit;
%end;
%mend;
%cre00(zd00,9);

出错信息：
ERROR: The following columns were not found in the contributing tables: zd001.
NOTE: The SAS System stopped processing this step because of errors.
NOTE: PROCEDURE SQL used:
   real time          0.01 seconds

解决了！！

%macro cre00(zd,i);
%do j=1 %to &i;
proc sql;
create table tch100&j
as select &&&zd&j from ipc_1580.suipc000&j where coilno in (select coilno from tmp0);
quit;
%end;
%mend;
%cre00(zd00,9);

你们这里解决问题的速度，太慢了！应该有个常驻班主才是呀

我一个人在这里自言自语，真没意思！！
