在 var 名称中有空格的 sas7bdat [英] sas7bdat with spaces in var names

问题描述

我收到了几个扩展名为 .sas7bdat 的 SAS 数据集文件.我在 Windows 上使用 SAS 9.3，这些文件的创建者显然使用了不同的环境和/或软件.许多文件的 var 名称包含空格和其他无效字符.即使运行 proc contents 也会引发这样的错误:

I've received several SAS dataset files with the .sas7bdat extension. I'm using SAS 9.3 on windows, and the creator of these files was evidently using a different environment and/or software. Many of the files have var names that include spaces and other invalid characters. Even running a proc contents raises an error like this:

ERROR: The value Person ID is not a valid SAS name.

奇怪的是，SAS Enterprise Guide 打开并显示文件没有任何抱怨.

Oddly, SAS Enterprise Guide opens and displays the file without complaining.

如何有效地重命名所有错误的 var 名称，以便我可以开始使用这些文件运行实际程序?

How do I efficiently re-name all my bad var names so that I can start running actual programs with these files?

推荐答案

除了 option validvarname=ANY; 你还需要引用变量名作为名称文字:'Person ID'n(单引号或双引号都可以).

In addition to option validvarname=ANY; you also need to reference the variable names as name literals: 'Person ID'n (either single or double quotes are fine).

如果你想有效地重命名所有这些，你可以这样做:

If you want to efficiently rename all of them, you can do something like this:

options validvarname=any;
data have;
'Hello Var'n = 1;
'Another Var'n = 2;
x=3;
run;

data badvarnames;
set sashelp.vcolumn;
where libname='WORK' and memname='HAVE' and not nvalid(name,'v7');
validname = translate(trim(name),'_',' ');
name = cats("'",name,"'n");
run;

proc sql;
select catx(' ','rename',name,'=',validname,';') into :renamelist
separated by ' ' from badvarnames;
quit;

proc datasets lib=work;
modify have;
&renamelist;
quit;

proc contents data=have;
run;

根据其他细节(例如这可能会导致变量名称重叠)，您可能需要针对这些问题调整代码.

Depending on other details (such as the possibility that this might create overlapping variable names), you might need to adjust the code for those concerns.
