在 SAS 中导入许多文件 .txt

Question

我编写了一个代码来同时将多个数据导入 SAS，但我想改进它，有人有什么建议吗？

filename indata pipe 'dir E:\Desafio_SAS\Dados /B'; 

data  file_list; 
    length arquivos$20.; 
    infile indata truncover ;
    input  arquivos $20.;  
    call symput('num_files',_n_); 
arquivos=compress(arquivos,',.txt');
run; 

CRIANDO UMA MACRO POR PROC SQL PARA GUARDAR O NOME DOS ARQUIVOS

proc sql;
  select arquivos into :lista separated by ' ' from file_list;
quit;
%let &lista;
%macro importar(arquivo=);
filename data "E:\Desafio_SAS\Dados\&arquivo..txt";
    data &arquivo;
    infile data dlm=" " missover dsd firstobs=2;
    input v0 (v1 - v8) ($);
    format v0 F16.;
    run;
%mend importar;
%macro fileout;
%do i=1 %to &num_files;
    %importar(arquivo=df&i);
        data df&i;
        set var_names df&i;
        run;
%end;
%mend fileout;
%fileout;
%macro excluiv0;
%do i=1 %to &num_files;
    data _null_;
    data df&i(drop = v0);
    set df&i;
    run;
%end;
run;
%mend excluiv0;
%excluiv0;

这只是代码的一部分。

Answer 1

您可以在 infile 文件规范中使用通配符。只要满足通配符的所有文件布局相同，就可以使用单一输入读取所有文件。

例子

* create three text files having same fields;

data _null_;
  file '%temp%\1.txt';
  put '1 2 3 abc';
  put '3 4 5 def';

  file '%temp%\2.txt';
  put '6 7 8 ghi';
  put '9 10 11 jkl';

  file '%temp%\3.txt';
  put '12 13 14 xyz';
  put '15 16 17 tuv';
run;

* read all three using wildcard in infile.  Save name of file whence 
* data cometh frometh;

data want;
  length _filename_ $250;
  infile '%temp%\?.txt' filename=_filename_;
  length source $250;
  length a b c 8 s $20;

  source = _filename_;
  input a b c s;
run;

通配符是

• ?, 0 或 1 任意字符
• *，任意数量的任意字符
