如何读取 SAS 数据集中的变量名称? [英] How to read variable names in a SAS data set?

问题描述

是否有任何语句\函数能够获取变量的名称?最好将它们放入另一个数据集的列、文本字段或宏变量中.

Are there any statements\functions capable of get the name of variables? Preferrably putting them into a column of another data set, a text field or a macro variable.

例如

- 数据集 1

Name age sex

    Jk   14   F
    FH   34   M

• 预期数据集

  • Expected data set

    Var_name_of_dataset1

    Name
    age
    sex
    

  PS:我知道一个语句:select into，它做某事相关它可以使用自定义分隔符将列的值读入字段，因此希望有类似的方法将列名读入字段或列.

  PS: I know a statement: select into, which does sth relevantly It can read the value of a column into a field with customized separetors, and therefore wish there are similar ways of reading column names into a field or a column.

  谢谢

  推荐答案

  PROC CONTENTS 将是在数据集中获取该信息的最快方法.列名称可以在列名称中找到.

  PROC CONTENTS would be the quickest way to get that information in a dataset. Column names can be found in the column NAME.

  proc contents data=sashelp.class out=contents noprint;
  run;
